PRP for Hair Loss: 8 Things to Know Before Your First Session

PRP (platelet-rich plasma) is one of the most requested hair treatments — and one of the most misunderstood. Here’s what to know before you book.

1. It uses your own blood. A small sample is spun to concentrate platelets, then injected into the scalp. Because it’s autologous, allergic reaction risk is very low.
2. It’s a course, not a one-off. Meaningful results usually need an initial series (commonly 3–6 sessions spaced weeks apart), followed by maintenance.
3. It suits early-to-moderate thinning. PRP works best where follicles are still alive but weakening — it stimulates, it doesn’t resurrect dead follicles.
4. Results take 3–4 months. You’ll typically notice reduced shedding first, then gradual thickening. Patience is part of the protocol.
5. Downtime is minimal. Mild tenderness or redness for a day is normal; most people return to routine immediately.
6. It pairs well with other treatments. PRP often works best alongside minoxidil, microneedling or nutritional correction rather than alone.
7. It won’t fix a fully bald area. Where follicles are already lost, a transplant is the appropriate option — PRP can then support the surrounding hair.
8. The cause still matters. If thyroid, deficiency or DHT sensitivity is driving your loss, PRP underperforms unless that’s treated too.

Frequently asked questions

Is PRP painful?

Discomfort is usually mild; clinics use a numbing option, and most patients tolerate it well with only brief tenderness afterward.

How long do PRP results last?

Results are maintained with periodic top-up sessions and by treating the underlying cause. Book an assessment at misterhair.in/hairtest.
