Platelet Rich Plasma (PRP) Hair Loss Therapy
Platelet rich plasma (PRP) has been well established in fields like dentistry and orthopedic surgery for its role in providing growth factors to areas of healing. It involves drawing one’s blood, spinning it down with a centrifuge, and then extracting off a the platelet rich portion for use in medical therapy. Platelets were once thought to only help with blood clotting, but we now understand that they secrete valuable cytokines and growth factors, including but not limited to the following:
-Platelet-derived growth factor (PDGF)
-Transforming growth factor (TGF)
-Vascular endothelial growth factor (VEGF)
-Insulin-like growth factor (IGF)
-Epidermal growth factor (EGF)
PRP for Hair Growth
Who is a Candidate?
PRP can be a great choice for patients who have already maximized other medical therapies.4. It can also be used in conjunction with hair transplantation, starting the first week after surgery and extending for 4-6 months after surgery.
Advantages of PRP:
-This procedure is very safe. PRP is completely autologous (derived from your own body) and does not introduce any foreign drugs or chemicals to your body.
-There are no drug interactions
-It does not require any lab testing
-No allergies have been reported
-The procedure requires just 30 minutes and can be done in the office
Disadvantages of PRP:
-Although this is safe, PRP has not been FDA approved as a medical therapy for male or female pattern hair loss. Various PRP devices have 510-K approval as medical devices only.
-We do not yet have large, multi-center, double-blind, placebo-controlled trials demonstrating the efficacy of platelet rich plasma for male or female pattern hair loss.
-Most of our data is based on in vivo, anecdotal studies and case reports
-There is still a wide array of protocols, none of which have been formalized
-It is unclear at this time whether PRP represent a single treatment course or requires ongoing therapy
Role of Microneedling
-There is evidence that skin wounding alone can contribute to hair regrowth. This is based on mouse studies showing hair follicle regeneration after wounding. Clinical studies have also shown successful hair regrowth using micro needling in men who failed to respond to other therapies. While the scalp is anesthetized, we recommend also making use of this additional method of hair regrowth.
