Does PRP Actually Work for Hair Loss? A Straight Answer

PRP — platelet-rich plasma — is the most over-promised treatment in hair loss. You will see it advertised as a cure and dismissed as a scam in the same week. The truth is narrower and more useful than either: it is a genuine, evidence-backed treatment that helps a specific group of people, and is wasted on others.

Here is how I decide whether it is worth your money.

What PRP actually does

We draw a small amount of your blood, spin it in a centrifuge to concentrate the platelets, and inject that plasma into the scalp. Platelets carry growth factors that can stimulate follicles which are still alive but shrinking — the early-to-middle stage of pattern hair loss where hairs are getting finer and shorter rather than disappearing outright.

The realistic outcome is reduced shedding, thicker existing hairs, and in some patients modest regrowth of miniaturised follicles. It is a strengthening and maintenance treatment, not a way to grow a new head of hair.

Who it helps — and who it does not

PRP works best for people with early thinning, recent diffuse shedding, or as support after a transplant. It is genuinely useful there.

It does nothing for a scalp where the follicles are already gone. If an area is smooth and bald, no injection will bring hair back — that area needs a transplant to move living follicles into it. Promising PRP regrowth on a bald crown is exactly the kind of overselling that gives the treatment a bad name.

PRP or PRGF?

PRGF — plasma rich in growth factors — is a more refined preparation that concentrates the growth factors further. It costs more (PKR 8,000 per session versus PKR 5,000 for standard PRP) and is the better choice for patients who want a stronger preparation or have not responded fully to standard PRP. For many people, standard PRP is enough; for others PRGF earns its higher price. We decide together after seeing how your scalp responds.

How many sessions, and when you will see anything

Plan for a starting course of three to four sessions about four weeks apart, then maintenance every four to six months. Hair grows slowly, so I ask patients to judge results at the three-to-four-month mark, not after the first session. If you are someone who wants an instant change, PRP will frustrate you — it rewards consistency.

The honest bottom line

If your hair is thinning but still there, PRP or PRGF is a sensible, affordable way to defend it — especially alongside good medical therapy. If you have already lost the hair, your money is better spent on a transplant. And if you are not sure which camp you are in, that is exactly what the first consultation is for.
