PRP has been used mostly for androgenetic alopecia and alopecia areata since these are the most common types of hair loss. Especially androgenetic alopecia is an extremely prevalent disorder resulting in gradual conversion of terminal hairs into vellus hairs. This is more obvious in men affecting more than 50%, with its well-known hair loss pattern, although there are studies suggesting an almost equal prevalence for women too. A self-renewal of the hair follicle by the keratinocyte stem cells of the bulge have been indicated in androgenetic alopecia, making growth factors signalling a promising future therapy.
