What is PRP Hair Restoration?
Studies published over the last 10-years have found PRP injection to be an effective treatment to stimulate new hair growth in both men and women. PRP, or Platelet Rich Plasma, is a treatment that uses growth factors derived and concentrated from the patient’s own blood in our lab. It is then injected into the patient’s scalp. Basically, PRP stimulates hair growth!
PRP is rich in bioactive growth factors.
PRP for hair growth occurs because PRP contains the growth factors found in whole blood, but now in a 4-10 times concentrated form. These growth factors are bioactive proteins that regulate the growth of various cell types. Different growth factor families include EGF, FGF, TGF-beta, KGF, PDGF, and VEGF, which have all been shown to be crucial for the regulation of the hair growth cycle.
What exactly do these growth factors do?
PRP stimulates hair growth and restores hair? Does it really work?
Hair growth cycles through 3-stages: Anagen, the growth phase, is where nourishment of the hair follicle enables hair growth which continues for 3-5 years. Catagen, the transition phase, is where the hair detaches from the follicle and signals the end of the growth phase. Telogen is when the detaches and falls out. After telogen, the follicle is reactivated and new hair growth begins. PRP stimulates hair growth during the anagen phase.
Evidence from published studies shows a definite beneficial role in hair regrowth. Most studies done to date conclude that PRP injections are effective for most forms of hair loss. Patients have rated their outcome satisfaction at greater than 70%. Realself.com surveys found a 92% patient approval rating. Individual results, of course, will vary.
This affordable treatment effectively can halt or reverse the thinning hair follicles. Hair regrowth will be gradual as new hair grows only in the anagen phase of the hair cycle.
What is the treatment like?
Once you arrive at the clinic, your blood will be drawn for processing. The doctor will anesthetize your scalp by injection. Conscious sedation is offered if you prefer. Once the PRP is processed it will be injected into your scalp with a small needle. You should expect to be in the clinic for about one hour, but most of this time is for the preparing of your PRP.
Results will not be noticeable for four to six months of treatment. Treatments should be performed every 4-6 weeks for 4-6 months to match the natural hair growth cycle. Follow up treatments every 6-12 months will maintain hair growth and renewal.
