Androgenic alopecia: what it is and what really works

By age 50, about half of men show visible signs of androgenic alopecia — and women aren't immune. If you've noticed a receding hairline, thinning crown, or general scalp thinning, this page gives clear, practical steps you can take right now. No hype, just what’s backed by evidence and what you can expect.

What causes androgenic alopecia?

Androgenic alopecia is driven by genetics and hormones. A sensitive response to dihydrotestosterone (DHT) shortens the hair growth cycle so hairs get thinner and shorter over time. For men this usually means a receding hairline and crown thinning. Women typically get diffuse thinning across the top of the head. Family history is a strong clue — check older relatives to see likely patterns.

Other factors can speed things up: smoking, poor nutrition, stress, and some medications. But if your hair loss follows a typical pattern and started gradually, DHT-related miniaturization is the most likely cause.

Proven treatments and realistic expectations

Want the short version? Minoxidil and DHT blockers are the two main non-surgical options that actually change results.

Minoxidil (topical) — Over-the-counter foam or solution applied daily. It helps keep hair you still have and can regrow some thin hairs. Expect 3–6 months to see change; stopping it brings hair back to the previous trend within months.

Finasteride (oral) — Prescription pill that lowers DHT. Many men see halted loss and some regrowth after 6–12 months. Side effects (lower libido, rare mood changes) affect a small number but should be discussed with your doctor.

Dutasteride — Works like finasteride but stronger. Often used off-label for hair loss; discuss risks with a specialist.

Low-level laser therapy and PRP — Devices and platelet-rich plasma injections can help in mild to moderate cases, usually as add-ons rather than primary fixes.

Hair transplant — Gives a permanent, visible change by moving resistant hairs to thin areas. Best when done by an experienced surgeon and if you understand donor limits and long-term planning.

Mixing treatments often works best: medical therapy to stop loss plus procedures for density. Set realistic timelines: medical treatments take months; surgical results take months to a year to settle.

When should you see a doctor? If loss is rapid, patchy, or accompanied by scalp redness or pain, book an appointment. See a dermatologist if you want a personalized plan, medication checks, or transplant evaluation.

Quick practical tips: use a gentle shampoo, eat protein and iron-rich foods, avoid tight hairstyles, and don’t expect overnight fixes. Track progress with photos every 3 months so you can tell what’s working.

Androgenic alopecia is common and manageable. With the right plan you can slow the clock and often get back considerable hair — but action and patience are key.
