Does PRP treatment show promise for naturally thin/fine hair (not thinning)?

PRP injections into the scalp work very well to activate the hair follicle and create hair thickening in areas the hair is thinning out.   Patients also experience hair growth in lenght and amazing texture.
in our office, patients are coming back very happy after only one treatment.  How many treatments are needed depends on the patient but normally around 3 or one a month x3 and  a maintenance is required wt a treatment quarterly.

yes PRP has been shown and proven to help grow and thicken hair. I would suggest you visit a provider near you to have your hair looked at in order to get a better idea if PRP is the best solution for you. Here at my clinic we have seen amazing results with PRP as far as thickening and growing hair

PRP (from an anecdotal perspective) has proven to be an effective tool in the arena of hair restoration both as an adjunct to grafting as well as standalone treatment for those who may not (yet) be a candidate for grafting. Patients have demonstrated slowed loss, thickening of existing hair and regrowth. The typical duration of effect is 6-9 months with most patients being treated 2x yearly (at least initially).
Ultimately, whether or not PRP will be effective will depend upon your diagnosis. Some causes of hair loss will respond better to other medical/chemical/surgical therapies. PRP is by no means a magic bullet.
As always, discuss your concerns with a board certified plastic surgeon (ABPS) with experience in hair restoration.
