In the medical treatment of male and female pattern baldness (androgenetic alopecia), PRP can be injected into the balding scalp to potentially stimulate thin (miniaturized) hair to grow into thicker (terminal) hairs. This is a relatively newer application of PRP. It was first described in 2006 by Dr. Uebel of Brazil to enhance growth with hair transplant surgery1. Since then, basic science studies have demonstrated that activated PRP can increase the proliferation of dermal papilla cells and can stimulate extracellular signaling via fibroblast growth factor (FGF-7) and beta-catenin2. One pilot study demonstrated clinically important differences seen in 40% and 54.7% of patients, according to the 2 evaluators, respectively 3. There are very recent studies, although small, are showing that PRP is effective in increasing the number and size of hair follicles4,5.  With newer techniques for isolation of the PRP and the activation of the PRP improvements in density of up to 40-56% are being obtained10.

Who is a Candidate?

PRP can be a great choice for patients who notice significantly reduced or thinning hair or who have already maximized other medical therapies6.   Patients with thinning, but not totally bald, areas would be the best candidates. The use of activated PRP (using calcium to stimulate the PRP prior to injection)  is now becoming more widely used as patients are getting better results with less treatments.

What is Platelet Rich Plasma (PRP)?

Platelet rich plasma (PRP) has been well established in fields like: dentistry,  wound healing and orthopedic surgery. It involves drawing one’s blood then isolating 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 (cell messengers) 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)
-Interleukin-1 (IL-1)
It is conjectured that the introduction of these substances, platelet rich plasma (PRP) can amplify the body’s naturally-occurring wound healing mechanism and stimulate regeneration of tissues.

Advantages of PRP Hair StimulationTherapy:

-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 45-60 minutes and can be done in the office under local (injectable/topical) anesthesia.

Disadvantages of PRP Hair Stimulation Therapy:

-Although this is safe, PRP has not been FDA approved as a medical therapy for male or female pattern hair loss. The PRP isolation device we use is  have FDA cleared.
-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. Although more data is needed, there continues to be improvement especially with the activated PRP10.
-Most of our data is based on in vivo, anecdotal studies and case reports.
-The ideal number of treatments may vary between 1-3 depending on the patient.

Low Level Laser Therapy for Hair Stimulation

Laser Hair Care® 670 operates 30-laser diodes in a rotating cap, because of the rotating cap the Laser Hair Care® 670 covers the whole scalp, optimizing the treatment. By using Low Level Laser Therapy (LLLT) we stimulate the microcirculation in the scalp, which helps the follicles to produce thicker and stronger hair. In normal cases a treatment lasts for 12months, with a total of ~40 sessions. Each session lasts for 15-20 minutes.

Role of Microneedling for Hair Stimulation

-There is evidence that skin wounding (microneedling) alone can contribute to hair regrowth. This is based on mouse studies showing hair follicle regeneration after wounding7. Clinical studies have also shown successful hair regrowth using micro needling in men who failed to respond to other therapies8,9.While the scalp is anesthetized, we recommend also making use of this additional method of hair regrowth.

In normal cases a treatment lasts for 12 months, with a total of ~40 sessions. Each session lasts for 15-20 minutes. It can be used alone or in combination with PRP to provide the best long term results.

Summary

PRP for hair loss is a relatively new treatment with a limited (but growing) number of scientific studies to show its efficacy. The long-term benefits of PRP treatments for hair loss are not yet known but the recent data shows significant improvement in number and size of new follicles in the treated areas. By harnessing the healing properties of one’s innate system and combining treatment modalities (PRP injections, PRP microneedling, LLLT) we maximize results with minimal side effects or risks. In our opinion it is a good option for those that wish to maximize the health of their scalp and hair to preserve and/or regain a more youthful appearance.
