PRP for hair uses platelet-rich plasma from your own blood, injected into the scalp where hair is thinning. Growth factors released by platelets are thought to prolong the growth phase of hair follicles and improve hair thickness. It is most useful in early androgenetic alopecia in men and women, and often works best alongside medical treatment. It does not regrow hair where follicles are lost.
