Androgenetic Alopecia: A Complete Dermatology Guide

Androgenetic alopecia is the most common cause of hair loss in men and women, and it's also one of the most mismanaged. Not because the treatments don't work. They do. But most people either start the wrong thing, quit too early, or never start at all because they got scared by something they read online. The condition itself is straightforward once you understand what's actually happening at the follicle level. The decisions that matter, like oral versus topical finasteride, when to add minoxidil, how to read your own progress, are where most people get lost. This is the complete picture.

The short version

Androgenetic alopecia is progressive hair thinning caused by a hormone called DHT (dihydrotestosterone), which shrinks hair follicles over time until they stop producing visible hair. It affects roughly 50% of men by age 50 and a significant number of women, particularly after menopause. The condition is genetic. If your parents or grandparents had it, your odds go up considerably.

The standard diagnostic approach is a clinical history plus a close look at the scalp, often with a dermatoscope. Labs are sometimes helpful to rule out other causes of thinning (thyroid issues, iron deficiency, nutritional gaps), but the pattern of loss itself is usually diagnostic.

First-line treatment for most men is finasteride (oral, 1 mg daily) to block DHT at its source, often combined with minoxidil to stimulate regrowth. For women, the options shift. Finasteride is used differently and typically only after menopause. Visible improvement takes time: you're looking at 6 to 12 months of consistent treatment before the results become hard to miss. The condition doesn't go away, but with the right plan it's very manageable.

What it actually is

Androgenetic alopecia is hair loss driven by your genetics and your hormones working together. The hormone that does the damage is DHT, dihydrotestosterone. DHT is a byproduct of testosterone. An enzyme called 5-alpha reductase converts testosterone into DHT, and DHT then binds to receptors on hair follicles that are genetically sensitive to it.

When DHT binds to those receptors, it gradually shrinks the follicle. The hair it produces gets thinner, shorter, and lighter with each growth cycle. Over time, the follicle miniaturizes to the point where it produces hair so fine you can't see it, or it stops producing hair altogether. That process is called follicular miniaturization, and it's the hallmark of androgenetic alopecia.

Not every follicle on your scalp is equally sensitive to DHT. The follicles at your temples, your crown, and across the top of your scalp tend to have more DHT receptors. The follicles along the sides and back of your head are usually resistant. That's why the classic pattern is thinning on top with preservation around the sides, the "horseshoe" pattern in advanced cases. The follicles aren't dying because of something you did wrong. They're responding to a hormone they were genetically programmed to respond to.

This also explains why finasteride works: if you block the enzyme that converts testosterone into DHT, you reduce the amount of DHT reaching those sensitive follicles. Less DHT means less miniaturization, which means the follicles can recover, at least partially, and start producing thicker, more visible hair again.

Who gets it (and why it's so often missed)

Androgenetic alopecia is extremely common. Roughly 50% of men show some degree of it by age 50, and it can start as early as the late teens or early twenties [per a 2014 review in the Journal of the American Academy of Dermatology]. In women, the prevalence increases significantly after menopause, though it can begin earlier, particularly in women with a family history or underlying hormonal conditions like polycystic ovary syndrome (PCOS).

The reason it gets missed, or more accurately, the reason people don't act on it, is that the early stages are subtle. You're not waking up to clumps of hair on your pillow. What's happening is a slow, gradual decrease in hair density that you might not notice for months or even years. The hair at your temples recedes slightly. The part in your hair looks a little wider. Your ponytail feels thinner. By the time most people think "I should probably do something about this," they've already lost a meaningful amount of density.

The other pattern I see constantly in practice: patients who've been told their hair loss is "just stress" or "just from a bad diet." Telogen effluvium, stress-related shedding, is real, and it does cause hair loss. But it looks different from androgenetic alopecia, and the treatments are different. Telogen effluvium causes diffuse shedding all over the scalp and is usually triggered by a specific event (illness, surgery, crash diet, major life stress). Androgenetic alopecia follows a pattern: temples, crown, midline. It progresses over years, not weeks. When a patient comes in convinced their thinning is stress-related but the pattern tells me it's androgenetic, the treatment plan changes completely.

Women get misdiagnosed more often than men. Female-pattern hair loss doesn't always follow the classic male pattern. Women tend to thin diffusely across the top of the scalp while maintaining their frontal hairline, which can look a lot like telogen effluvium or iron-deficiency-related thinning. Getting the diagnosis right matters because the treatments are different for each of those conditions.

The signs and symptoms, and what they're often confused with

Gradual thinning at the temples and crown. This is the classic presentation in men. It starts with the hairline receding at the temples and thinning at the vertex (the crown). Early on, it can be confused with a naturally maturing hairline, which is a real thing and not the same as androgenetic alopecia. The difference is progression: a maturing hairline stabilizes, while androgenetic alopecia keeps going.

Widening part line. More common in women. The part gradually widens as the hair density across the top of the scalp decreases. This gets confused with telogen effluvium or thyroid-related hair loss. The distinguishing feature is the pattern: androgenetic alopecia preserves the frontal hairline in women while thinning the midline and crown. Telogen effluvium thins everywhere, including the sides.

Increased shedding. Many patients notice more hair in the shower drain or on their pillow. On its own, shedding isn't diagnostic. Everyone sheds 50 to 100 hairs a day normally. But increased shedding combined with visible thinning in a patterned distribution points toward androgenetic alopecia. When the shedding is sudden and dramatic (hundreds of hairs a day), telogen effluvium is more likely.

Finer hair texture over time. The hair that grows back in affected areas is thinner, shorter, and less pigmented than it used to be. This is the miniaturization process in action. Patients often describe it as their hair feeling "wispy" or "see-through." This gets confused with aging-related hair changes, which are real but don't follow the same patterned distribution.

Scalp visibility through the hair. In more advanced cases, the scalp becomes visible through the hair, especially in bright light or when the hair is wet. This is when most patients seek help, and it's often later than ideal, because the earlier you start treatment, the more follicles you have to work with.

---

How it's diagnosed

Diagnosing androgenetic alopecia is primarily clinical, meaning the pattern of loss, your history, and a close examination of the scalp usually tell the story.

The first step is a detailed history. When did you first notice thinning? Is it getting worse gradually or did it happen suddenly? Any family history of hair loss? Any recent major stressors, illnesses, surgeries, or medication changes? Are you on any new supplements? For women: any changes in your menstrual cycle, new hormonal symptoms, or recent pregnancy? These questions narrow the differential quickly.

The second step is examining the scalp. With a dermatoscope, a magnifying instrument with special lighting, I can see follicular miniaturization directly. I'm looking for variation in hair shaft diameter across the scalp: a mix of thick terminal hairs and thin, miniaturized hairs in the affected areas is the hallmark of androgenetic alopecia. I'm also looking at the pattern of involvement. Temples, crown, and midline versus diffuse thinning everywhere.

Labs are sometimes useful, particularly to rule out other contributors. A thyroid panel (TSH, free T4), ferritin, CBC, and sometimes a hormonal panel (DHEA-S, testosterone, in women) can identify conditions that either mimic androgenetic alopecia or compound it. These are standard outpatient labs, orderable through a chat consultation and interpreted alongside your history and photos.

For the vast majority of presentations, a biopsy isn't needed. The clinical picture is clear enough. If the pattern is atypical, if it doesn't fit neatly into androgenetic alopecia or any other recognizable pattern, a scalp biopsy can distinguish between different types of alopecia (scarring versus non-scarring, for example). That's the scenario where I'd recommend in-person evaluation. But in most cases, we can diagnose and start treatment through chat based on your history, photos, and labs, and use how you respond to treatment to confirm the working diagnosis.

Treatment landscape

Treatment for androgenetic alopecia falls into a few tiers, and the right combination depends on where you are in the process, what you're comfortable with, and what your goals are.

First-line: finasteride. For men, oral finasteride 1 mg daily is the gold standard. It blocks the enzyme (5-alpha reductase) that converts testosterone to DHT, reducing DHT levels systemically. That means every follicle on your scalp benefits, not just the ones you can see thinning. I personally favor oral finasteride over topical for most patients because it's more effective, easier to stick with, and treats the entire scalp rather than just the areas you apply it to. Topical finasteride is a reasonable option for patients who are very concerned about side effects, but the tradeoff is somewhat lower efficacy and the hassle of daily application. Different dermatologists weigh that tradeoff differently, and that's a legitimate clinical choice. The evidence supports both routes.

First-line adjunct: minoxidil. Minoxidil (topical or oral) stimulates hair growth through a different mechanism. It increases blood flow to the follicle and extends the growth phase of the hair cycle. It doesn't address DHT directly, so it works best in combination with finasteride rather than alone. Topical minoxidil (5% for men, 2% or 5% for women) is the over-the-counter option. Low-dose oral minoxidil is gaining traction as an alternative for patients who find the topical version messy or irritating.

Second-line: combination and escalation. For patients who don't respond adequately to finasteride plus minoxidil, options include increasing finasteride dose (under supervision), adding low-dose oral minoxidil if they were only on topical, or considering platelet-rich plasma (PRP) injections, which require in-person visits. Dutasteride, a more potent 5-alpha reductase inhibitor, is sometimes used off-label for hair loss when finasteride alone isn't enough. I'll flag that as off-label when I prescribe it, and I explain why I think it's defensible for that patient's situation.

Adjunct: prescription-strength shampoos. Ketoconazole shampoo has mild anti-androgenic properties at the scalp level and can help with seborrheic dermatitis, which often coexists with androgenetic alopecia and can contribute to shedding.

For women: the treatment landscape shifts. Finasteride is used at different doses and typically only after menopause due to teratogenicity risks. Spironolactone (an anti-androgen) is often the first-line hormonal option for premenopausal women. Topical minoxidil remains a mainstay.

I have no incentive to push one medication over another. The consultation is what I charge for, so the recommendation reflects what fits your situation, not a formulary.

What treatment actually feels like, week to week

This is the part most articles skip, and it's the part that matters most for whether you actually stick with treatment.

Weeks 1 to 4: You start the medication. Nothing visible happens. Some patients on minoxidil notice increased shedding in the first few weeks. This is the "minoxidil shed," and it's actually a good sign. It means the medication is pushing older, miniaturized hairs out of the follicle to make room for new growth. It's alarming if you don't know to expect it.

Months 1 to 3: Still nothing visible to the naked eye. With a dermatoscope, I can sometimes see early signs: fine vellus hairs forming in previously bare areas, slight changes in hair shaft diameter. But you won't see this in the mirror. This is the window where most people quit, and it's the worst time to quit.

Months 3 to 6: Shedding typically stabilizes. Some patients start noticing that their hair feels slightly thicker, or that they're losing less hair in the shower. Photos taken in the same lighting may start showing subtle differences. This is the "is it working?" phase, and the honest answer is usually "yes, but you need more time."

Months 6 to 12: This is when the results become visible. Hair density improves, thin areas fill in, and the overall quality of the hair (thickness, texture, coverage) gets noticeably better. Month 12 is really when patients look at their before-and-after photos and see meaningful change.

Beyond 12 months: Maintenance. The gains you've made hold as long as you stay on treatment. If you stop finasteride, DHT levels return to baseline and the miniaturization process resumes. This is a long-term commitment.

On FutureClinic, that trajectory isn't a one-shot conversation. Your same doctor is in the chat as you experience it, so adjustments happen as the response unfolds, not at the next six-month visit.

Side effects, monitoring, and how the plan adjusts

The side effect conversation around finasteride is the most overblown topic in hair loss. The side effects are real. They're also rare, and they're manageable.

Sexual side effects (oral finasteride). The most discussed concern is changes in libido, erectile function, or ejaculate volume. In clinical trials, these side effects occurred in roughly 2 to 4% of men taking finasteride 1 mg daily, which means 96 to 98% of men experienced no sexual side effects at all [per the original Merck trials and subsequent meta-analyses]. When side effects do occur, they're usually mild and often resolve either with continued use or after stopping the medication.

What I tell patients: libido and erectile quality vary day to day. That's normal physiology. Once you start a medication you're anxious about, you become hyper-aware of every fluctuation. It's genuinely hard to separate "the medication is doing this" from "I'm monitoring myself so closely that I'm noticing normal variation I never paid attention to before." Having a doctor who knows these medications well and can walk you through that distinction honestly makes a real difference.

Topical finasteride and side effects. Topical finasteride does reduce systemic DHT exposure compared to oral, which is why the side effect profile is somewhat better. But "somewhat" is the key word. There is still systemic absorption with topical finasteride. It's not a perfectly local treatment. The idea that topical finasteride is "side-effect-free" is marketing, not medicine.

Minoxidil side effects. Topical minoxidil can cause scalp irritation, dryness, or flaking, usually from the propylene glycol in the solution, not the minoxidil itself. Switching to a foam formulation often fixes this. Oral minoxidil at low doses can cause fluid retention, slight drops in blood pressure, or increased body hair (hypertrichosis). These are dose-dependent and manageable.

Monitoring. For oral finasteride, no routine blood work is typically needed. The medication is well-studied and the safety profile is established. For oral minoxidil, I'll sometimes check blood pressure and watch for signs of fluid retention, especially in patients with cardiovascular history. For women on spironolactone, periodic potassium levels are standard.

Adjusting the plan. If a patient reports side effects, the first step is an honest conversation about whether what they're experiencing is likely medication-related or coincidental. If it's genuinely medication-related, we adjust: reduce the dose, switch the route (oral to topical or vice versa), or try a different medication altogether. The plan isn't set in stone. It evolves based on how you respond.

Lifestyle and self-management: what moves the needle and what doesn't

I'm going to be direct about this: the lifestyle factors that move the needle for androgenetic alopecia are fewer than most articles suggest.

What actually matters:

• Manage coexisting scalp conditions. Seborrheic dermatitis and dandruff are common in patients with androgenetic alopecia, and untreated scalp inflammation can contribute to shedding. A prescription-strength ketoconazole shampoo used 2 to 3 times a week addresses both the fungal component and has mild anti-androgenic effects at the scalp. Most people overlook this because they think of dandruff and hair loss as separate problems. They're often connected.
• Manage stress and sleep. Chronic stress and poor sleep can trigger telogen effluvium, a type of diffuse shedding that stacks on top of the androgenetic thinning you're already dealing with. This isn't a wellness platitude. Telogen effluvium from sustained stress is a real, measurable phenomenon, and it compounds the visual impact of androgenetic alopecia.
• Avoid crash diets and dramatic caloric shifts. Sudden, severe caloric restriction is one of the most reliable triggers for telogen effluvium. If you're going to change your diet or ramp up your training, do it gradually. The metabolic shock of a crash diet can cause a wave of shedding 2 to 3 months later.

What doesn't matter as much as the internet suggests:

• Specific supplements (biotin, saw palmetto, collagen). Biotin deficiency can cause hair loss, but actual biotin deficiency is rare in people eating a normal diet. Supplementing biotin when you're not deficient doesn't improve hair. Saw palmetto has weak evidence as a DHT blocker, nowhere near the efficacy of finasteride. Collagen supplements have no meaningful evidence for androgenetic alopecia.
• Special shampoos (outside ketoconazole). "Hair growth" shampoos without active pharmaceutical ingredients are marketing. A gentle, non-stripping shampoo is fine. You don't need a $40 bottle with caffeine and biotin in it.
• Scalp massages. There's a small body of evidence suggesting scalp massage may increase hair thickness, but the effect size is tiny compared to finasteride or minoxidil. It's not harmful, but it's not a treatment.

Complications and what to watch for

Androgenetic alopecia isn't medically dangerous. It doesn't cause pain, it doesn't affect organ function, and it doesn't progress to anything life-threatening. But the psychological impact is real and worth naming honestly.

Patients who delay treatment, especially younger patients who notice thinning in their twenties, often end up in a worse position than they needed to be. The follicles that have fully miniaturized are much harder to recover than follicles that are still in the early stages of thinning. Starting treatment when you first notice a problem gives you the most follicles to work with. Waiting two or three years means some of those follicles may be past the point where medication alone can bring them back.

The other complication I see is treatment discontinuation. Patients start finasteride, see improvement at month 8 or 10, feel good about their hair, and stop the medication, either because they think they're "cured" or because they get nervous about long-term use. Within 6 to 12 months of stopping, the miniaturization process resumes and the gains reverse. This isn't a course of antibiotics. It's a maintenance medication. Understanding that upfront saves a lot of frustration.

For women, untreated androgenetic alopecia can progress to the point where the scalp is clearly visible through the hair across the entire top of the head. This is harder to reverse than early-stage thinning, and the treatment options for women are narrower than for men.

When to seek care vs. wait it out

Emergencies first. Androgenetic alopecia itself doesn't have emergent presentations. But sudden, rapid hair loss (large clumps coming out over days, circular bald patches appearing overnight, hair loss accompanied by scalp pain, burning, or scarring) is not androgenetic alopecia. These presentations can indicate alopecia areata, scarring alopecia, or other conditions that need prompt evaluation. If you notice sudden patchy hair loss with scarring or skin changes on the scalp, see a doctor promptly. If there are signs of a systemic illness (fever, weight loss, joint pain alongside hair changes), that warrants urgent medical attention.

The middle tier: this is what the chat is for. If you've noticed gradual thinning that's been progressing over months or years, if your hairline is receding or your part is widening, if you've tried over-the-counter minoxidil and aren't sure if it's enough, this is exactly the kind of presentation that a chat consultation handles well. I can review your photos, take a detailed history, order labs if needed to rule out other contributors, and build a treatment plan that fits your situation. Most people in this category delay care because of cost, scheduling, or the assumption that hair loss isn't "serious enough" to warrant a doctor's time. It absolutely is. And self-treating with supplements or over-the-counter products alone often fails because the diagnosis was incomplete. Maybe there's an iron deficiency contributing, or a thyroid issue, or the thinning pattern calls for a prescription medication that over-the-counter options can't replace.

A real consultation with a real doctor: diagnoses, prescriptions, labs, just through chat, between you and a doctor. Same medicine, same depth, same doctor staying with you. What's different is that you start it from your phone whenever you're ready, and most replies come back the same day. You can either keep researching finasteride on Reddit threads and supplement forums, or you can spend the same fifteen minutes in a chat with a board-certified dermatologist who can actually look at your photos, pull your records, order the right labs, and write the prescription if that's the right call.

The "I can manage this with information" tier. If your thinning is very early and you're not ready for medication, the actionable steps are: start documenting with consistent photos (same lighting, same angle, monthly), use a ketoconazole shampoo 2 to 3 times a week, manage your stress and sleep, and avoid crash diets. If the thinning progresses despite this, that's your signal to talk to a doctor.

The honest take

Here's what I want you to understand about androgenetic alopecia that most content online gets wrong.

The topical-versus-oral finasteride debate is framed as if topical is the "safe" version and oral is the "risky" version. That framing is incomplete. Topical finasteride does reduce systemic DHT exposure, but there's still systemic absorption. You're not eliminating the possibility of side effects. You're reducing it somewhat. Meanwhile, you're also reducing efficacy and adding the hassle of a messy daily application with variable compounding quality depending on the pharmacy. I used to recommend topical finasteride more confidently as a way to get the benefits with fewer risks. My thinking has shifted. In practice, oral finasteride just produces better results, not only because patients stick with a pill more reliably, but because it improves hair quality across the entire scalp, not just the spots where you'd be applying a topical.

The side effect fear is the other thing I'd push back on. There is way too much fixation online on finasteride side effects. The side effects are real. I'm not dismissing them. But they occur in a small minority of patients, they're usually mild, and they're manageable. What's unfortunate is how many people are missing out on treatment that would genuinely help them because they've become paralyzed by stories they read online. The volume and intensity of the fear is disproportionate to the actual incidence. Patients would be much better served working closely with their dermatologist, having someone who can coach them through the early months, help them distinguish normal variation from actual side effects, and adjust the treatment if something genuinely isn't right.

Consistency is the most important part of improvement, and it's entirely under your control. The patients who do well are the ones who start treatment, stick with it through the months where nothing seems to be happening, and trust the process. The patients who struggle are the ones who start and stop, switch medications every few weeks, or quit at month four, right before the payoff starts.

Frequently asked questions

Does finasteride work for everyone?

Finasteride works for the majority of men with androgenetic alopecia. In clinical studies, roughly 80 to 90% of men on finasteride 1 mg daily either maintained their hair or saw improvement over a two-year period [per long-term extension studies of the original Phase III trials]. "Not working" usually means one of two things: the patient hasn't given it enough time (visible results take 6 to 12 months), or the medication stabilized their loss without producing dramatic regrowth, which is still a clinical success, even if it doesn't feel like one.

Can women take finasteride?

Finasteride is used in women, but with important caveats. It's typically reserved for postmenopausal women because finasteride can cause birth defects if taken during pregnancy. The dosing is different from what's used in men. For premenopausal women, spironolactone is usually the first-line anti-androgen option. This is a conversation that needs to happen with a dermatologist who treats female hair loss regularly.

What happens if I stop taking finasteride?

If you stop finasteride, DHT levels return to baseline and the miniaturization process resumes. Most patients who discontinue finasteride see their hair loss progress back to where it would have been without treatment within 6 to 12 months. The gains don't persist without the medication. This is a maintenance treatment, not a cure.

Is topical finasteride really safer than oral?

Topical finasteride has a somewhat lower side effect profile than oral, but it's not side-effect-free. There is systemic absorption with topical application. Some of the medication gets into your bloodstream regardless. The side effect risk is reduced, not eliminated. Meanwhile, the efficacy is also somewhat lower, and the quality of compounded formulations varies significantly depending on the pharmacy. The idea that topical finasteride is a completely different safety category from oral is overstated.

How do I know if my hair loss is androgenetic alopecia or something else?

The pattern of loss is the biggest clue. Androgenetic alopecia follows a predictable distribution: temples, crown, and midline in men; diffuse thinning across the top with frontal hairline preservation in women. If your hair loss is sudden, patchy, or diffuse without a clear pattern, other diagnoses are more likely (telogen effluvium, alopecia areata, thyroid-related loss, iron deficiency). A dermatologist can usually distinguish these with a history, photos, dermatoscopy, and sometimes labs. This is exactly the kind of evaluation a chat consultation is built for. Send photos, walk through your history, and get a real answer for your specific pattern.

Can minoxidil alone treat androgenetic alopecia?

Minoxidil alone can help, but it doesn't address the root cause. Minoxidil stimulates hair growth and extends the growth phase of the hair cycle, but it doesn't block DHT. For most patients with androgenetic alopecia, using minoxidil without finasteride means you're stimulating growth while the underlying miniaturization process continues. The combination of both is more effective than either alone.

Do hair growth supplements work?

Most hair growth supplements have weak or no evidence for androgenetic alopecia. Biotin supplementation only helps if you're actually biotin-deficient, which is uncommon in people eating a normal diet. Saw palmetto has mild 5-alpha reductase inhibitory activity, but the effect is nowhere near finasteride. Collagen, keratin, and most "hair vitamin" blends have no rigorous evidence supporting their use for androgenetic alopecia. If you're spending money on supplements instead of proven treatments, you're likely delaying real improvement.

How long do I need to take finasteride?

Indefinitely, as long as you want to maintain the results. Androgenetic alopecia is a progressive condition driven by ongoing DHT exposure. Finasteride manages it by keeping DHT levels suppressed. When you stop the medication, DHT returns to baseline and the process resumes. Most patients who do well on finasteride plan to stay on it long-term.

What about the "post-finasteride syndrome" I've read about online?

Post-finasteride syndrome, persistent sexual or neurological side effects after stopping finasteride, is reported by some patients online, but it remains poorly understood and controversial in the medical literature. Large-scale studies have not consistently demonstrated a causal link, and the condition doesn't have a universally accepted diagnostic definition. That said, I take every patient's reported experience seriously. If someone on finasteride reports side effects, we address them: reduce the dose, switch the route, or stop the medication entirely. The important thing is having a doctor who listens, takes your concerns seriously, and adjusts the plan accordingly.

Are there new treatments coming?

Yes, and a couple are genuinely exciting. PP405 is a topical medication in development that targets dormant follicles through a non-hormonal mechanism, completely different from finasteride. Early results are promising, though it likely won't be widely available until after 2028. VDPH101 is a delayed-release reformulation of oral minoxidil that keeps the drug in the therapeutic range longer, potentially improving efficacy while reducing side effects like fluid retention. Both are worth watching, but neither replaces what's available and proven right now.

Should I see a dermatologist for hair loss, or can my primary care doctor handle it?

A board-certified dermatologist who treats hair loss regularly is the best fit for this condition. Primary care doctors can prescribe finasteride, and many do a good job with straightforward cases. But the nuances, like distinguishing androgenetic alopecia from other types of hair loss, choosing between treatment routes, monitoring response with dermatoscopy, adjusting the plan when the first approach isn't enough, are where dermatology-specific training matters. I've seen patients who weren't improving because the compounding was off, or who were on a formulation that wasn't appropriate for them, because no one with deep experience in hair loss was overseeing the treatment.

Bottom line

Androgenetic alopecia is common, progressive, and very treatable, but the treatment only works if you start it, stick with it, and have a doctor who knows how to adjust the plan as you go. The earlier you start, the more follicles you have to work with. Consistency is the most important part of improvement, and it's entirely under your control.
