Some in the medical community think that PRP injections trigger natural hair growth and maintain it by increasing blood supply to the hair follicle and increasing the thickness of the hair shaft. Sometimes this approach is combined with other hair loss procedures or medications.
There hasn’t been enough research to prove if PRP is an effective hair loss treatment. However, PRP therapy has been in use since the 1980s. It’s been used for problems such as healing injured tendons, ligaments, and muscles.
PRP therapy is a three-step process. Most PRP therapy requires three treatments 4–6 weeks apart.
Maintenance treatments are required every 4–6 months.
Your blood is drawn — typically from your arm — and put into a centrifuge (a machine that spins rapidly to separate fluids of different densities).
After about 10 minutes in the centrifuge, your blood will have separated into in three layers:
- platelet-poor plasma
- platelet-rich plasma
- red blood cells
The platelet-rich plasma is drawn up into a syringe and then injected into areas of the scalp that need increased hair growth.
There hasn’t been enough research to prove whether PRP is effective. It’s also unclear for whom — and under what circumstances — it’s most effective.

- your geographic location
- quality of equipment
- the addition of nutritive components
Many insurance plans consider PRP for hair loss treatment to be cosmetic and don’t cover any of the costs of the treatment. Check with your insurance provider to see if PRP therapy is covered for you.
Although there’s limited clinical proof that PRP for hair loss works, there are many who believe that PRP is a safe and effective way of reversing hair loss and stimulating new hair growth.
