The growth factors, when released, promote tissue repair, angiogenesis (capillary formation), collagen production, and encourage normalization of the hair follicular unit. Most importantly, evidence suggests PRP can reverse the miniaturization process of hair follicles (a result of dihydrotestosterone, DHT), when injected into the balding areas of the scalp. PRP contains many growth factors that stimulate the hair follicle’s growth and can be used pre-operatively, intra-operatively, or post-operatively.
The PRP treatment approach involves drawing the patient’s own blood and spinning it to isolate the plasma that is enriched with growth factors. This plasma is then injected into the areas of hair loss and results start to be noticeable in about 90 days. Results can take up to a year. PRP can be used alone or safely combined with all other hair therapies such as transplantation, low-level laser therapy and topical and oral treatments.
