PRP (platelet-rich plasma) is a nonsurgical treatment for hair-loss in which platelets are extracted from blood and are injected into areas with thinning hair on the scalp. PRP therapy is still not FDA-approved as hair loss treatment, however, the studies done on PRP have found it to be safe and effective for both age-related hair loss and pattern baldness. It is considered an inexpensive, and less invasive treatment option to surgery. PRP stimulates the hair follicles, slows down hair loss and helps in new hair growth.
During PRP treatment, platelets are centrifuged from your blood and separated to concentrate the growth factors. After injecting into scalp, PRP increases the blood flow to hair follicles and stimulates the growth of new and dormant follicles. It lengthens the anagen (active) phase of the hair cycle resulting in increased number of hair follicles and increased thickness of the hair shaft.”
Pros and Cons of PRP therapy for hair loss?
- PRP therapy is nonsurgical and safe with no downtime. The entire procedure takes about 45 minutes.
- Both men and women respond well to PRP treatment in terms of increased hair thickness and growth
- Primary objective of the PRP therapy is to slow down or stop the progression of hair loss.
- This treatment is inexpensive as compared to hair transplant surgery.
- Results are temporary. Up to six treatments may be required spaced 4-6 weeks apart, and maintenance treatments every few months thereafter.
- PRP results depend on the extent and duration of hair loss. The earlier PRP is administered after hair loss onset the better. People with long standing baldness and large areas of baldness don’t usually get good results in terms of hair regrowth, but PRP can still be used to stop further progression of hair loss.
- PRP does not work in 100% of patients.
