New Study: Platelet-Rich Plasma Therapy Increases Hair Growth by 24 Percent


Patients treated with PRP experience 42 percent increase in hair thickness

A new analysis of evidence regarding Platelet-Rich Plasma (PRP) Therapy confirms that it can activate dormant hair follicles and reverse thinning hair. The article, “Platelet-rich plasma for androgenetic alopecia: Does it work? Evidence from meta analysis,” was published in the Journal of Cosmetic Dermatology.

PRP Therapy is a scalp treatment procedure that uses the cells involved in tissue healing to treat hair loss. It utilizes a patient’s own blood to rejuvenate thinning hair. At Arocha Hair Restoration, we begin PRP Therapy with the extraction of a small amount of blood, which is placed in a closed system centrifuge to separate the platelet-rich plasma from the whole blood. This concentrated platelet rich plasma is mixed with ACell, an FDA approved cellular regeneration product, and then injected into the scalp treatment area.

These cells are rich in the growth factors that promote tissue healing.

The article examined six different studies involving 177 patients who used PRP to stimulate scalp hair. Dr. Giordano’s findings confirmed the effectiveness of PRP to increase hair growth, with a 24 percent increase in hair per square cm with PRP. Additionally, Dr. Giordano reports the percentage increase in cross-sectional hair thickness for those who underwent PRP Therapy was 42 percent after treatment.

The effects were seen in both men and women.

These findings reflect the very positive patient results we at Arocha Hair Restoration have observed among patients who have benefitted from PRP Therapy. Often, we see thinning reversed, yielding a restoration of the patient ‘s hair fullness. Moreover, PRP Therapy has shown to be well tolerated in patients. We apply a topical anesthetic to minimize discomfort, and patients often describe a mild “sunburn” sensation following the procedure which typically dissipates quickly. There may also be minor pinpoint bleeding during the procedure. We recommend that patients avoid taking anti-inflammatory medication since it may interfere with the natural healing process stimulated by the PRP.

The lead author of the paper, Salvatore Giordano, MD, PhD is an adjunct professor in plastic surgery at the University of Turku in Finland. In an article in Cosmetic Surgery Times, he said the findings support trying PRP Therapy prior to and in tandem with hair transplants.

“PRP contains a large number of growth factors like platelet-derived growth factor (PDGF), transforming growth factor (TGF)-b, FGF and vascular endothelial growth factor (VEGF) — all participating in tissue renovation,” said Dr. Giordano.

Dr. Giordano recommends an initial series of three to four treatments, each one spaced three weeks apart, followed by a maintenance program of one PRP treatment every six months going forward.

One simple reason for following a maintenance program is that the condition responsible for hairloss in androgenetic alopecia is the genetic inheritance of a pattern of hair that is sensitive to the miniaturizing effect of DHT on these follicles. Hence if PRP Therapy is terminated in the future, the benefit may be lost.

One thing Dr. Giordano’s review did not take into consideration is that the quality of PRP Therapy can vary greatly, which can have a significant impact on patient results. At Arocha Hair Restoration, we understand that the training and proficiency of the staff, along with strict adherence to preparation protocols, centrifuge settings, preparation kits and the use of ACell all contribute to positive patient outcomes.

Also worth noting is that unfortunately, patients with an absence of hair follicles are not good candidates for PRP Therapy. Healthy hair follicles need to be present for PRP to stimulate new hair growth.
