Male pattern hair loss is not hair falling out — it is follicles shrinking. Under DHT, genetically sensitive follicles at the temples and crown produce progressively finer, shorter hairs until they produce none. The strategy follows the biology: defence early beats rescue late.

Testosterone converts to DHT via 5-alpha-reductase; in men with the inherited sensitivity, DHT progressively miniaturises follicles at the temples and crown — the Hamilton–Norwood map. Each growth cycle the affected follicle produces a finer, shorter hair, until it is a barely-visible vellus hair, and finally silent. Clinical reviews frame it plainly: pattern loss is treatable and worth treating, and treatment works best on follicles that are miniaturising, not gone [1]. The occipital fringe is DHT-resistant — the biology behind both the pattern and transplantation.
Two pharmacological anchors carry decades of randomised evidence: finasteride, which lowers DHT at its source, and minoxidil, which supports follicle activity — reviewed as first-line in pattern hair loss [1]. Dr Sin Yong's male programme and medication page cover suitability and side-effect counselling honestly; adjuncts — Regenera Activa micrografting, the H2LT laser protocol — build on that base, not instead of it. A hairline held for a decade is a treatment success even if the mirror never changes: in this disease, unchanged is the win.
Caffeine shampoos and biotin (without deficiency) have marketing, not trial evidence. “Waiting to see how bad it gets” is the costliest strategy in the field — every year of DHT exposure retires more follicles beyond rescue. And a transplant into an untreated scalp relocates hairs onto a battlefield where the native loss continues around them: medical control first is the honest sequence.
“A hairline is easier to hold than to reverse — the earlier it is defended, the more survives.”
— Dr Sin Yong
Every month a man waits to 'see how bad it gets', the answer arrives with fewer follicles left to save. Pattern loss treatment defends hair that still exists — miniaturised is recoverable, bare is mostly not. The best consult I do is the one that happens two years earlier than the patient planned.

A maturing hairline shifts slightly and evenly in the late teens to twenties and stabilises. Progressive temple recession that continues, or crown thinning, is pattern loss.
Reported sexual side effects affect a small minority in trials and typically resolve on stopping. This deserves an honest physician conversation, not a forum verdict — either direction.
No — by any treatment, at any price. Miniaturising follicles can be rescued; silent ones cannot. This is why timing dominates outcome.
Hair cycles are measured in months. Three to six months is the honest minimum before judging any regimen; visible change often trails biological change.
It relocates DHT-resistant follicles — it does not stop the disease. Untreated, native loss continues around the grafts. Control first, transplant as a planned step if needed.
Inheritance is polygenic, from both sides. Family history informs risk; your own temples and crown, examined over time, are the real data.
