Medical therapy

Hair loss medication

Surgery restores what has been lost. Medication defends what has not. Treating them as alternatives is one of the more expensive mistakes in hair restoration.

Why both

Two different jobs

Transplanted follicles come from the DHT-resistant donor zone, so they are durable. The native hair around them is not — it carries the same genetic sensitivity it always did, and it keeps miniaturising on its own schedule.

That is the mechanism behind a specific and common disappointment: a technically good transplant that looks worse at year five, not because the grafts failed but because everything around them thinned. A medical plan is what prevents it.

Which medication, at what dose, and whether it is appropriate for you at all is a clinical decision that depends on your history. This page is orientation, not a prescription.

The main options

What these actually do

Finasteride

An oral 5-alpha-reductase inhibitor that lowers DHT. The most established option for slowing pattern loss in men. Carries a recognised risk of sexual side effects in a minority of users and requires a physician conversation.

Minoxidil

Topical or oral, and it works differently — extending the growth phase rather than blocking DHT. Commonly causes an initial shedding phase and scalp irritation.

Topical protocols

Combination formulations prepared for the individual. Suitability varies, and evidence quality varies with it.

PRP therapy

Platelet-rich plasma from your own blood, used to support follicles that are miniaturising but still active. Not a replacement for surgery and not permanent.

Timing

Sometimes medication comes first

If your loss is still moving quickly, stabilising it medically before operating is usually the right sequence — occasionally for a year or more. Placing grafts into an actively receding pattern is how people end up with an island of transplanted hair and a widening gap behind it.

That means a legitimate outcome of a consultation is a prescription and a review date rather than a surgery date.

Straight answers

Questions

Usually, yes. Surgery moves hair; it does not stop the genetic process thinning the hair around it. Without a medical plan you can end up with a good transplant surrounded by continuing loss.

Yes, and they should be discussed with a physician who knows your history. Finasteride carries a recognised risk of sexual side effects in a minority of users. Minoxidil commonly causes scalp irritation and an initial shedding phase. Neither is a decision to make from a web page.

The hair these treatments were protecting resumes thinning. They control an ongoing process rather than curing it, so any benefit lasts as long as the treatment does.
