PRP may not significantly promote regrowth in areas with insufficient hair follicles, but can boost volume in other thinning areas by 20-50%.

“if someone comes in with a receding hairline they say hey I doc I really want PRP here the receding hairline if they're hoping for some regrowth chances are that they're not going to get too much action there because why we talked about that that there's just you know yeah in that area there's not enough trees in the garden so to speak when we are plants in the garden when we go to fertilize but the other zones that they didn't even realize we're thinning we're gonna get a 20 to 50 percent boost in volume in many of those areas”
