Clinical alopecia occurs due to miniaturization of the hair shafts as well as loss of active production of hair shafts. PRFM has been shown to induce dermal angiogenesis, and anecdotal findings of improvement of hair appearance after PRFM injection in the scalp suggest that PRFM may play a role in the treatment of thinning hair. Patients will be treated on a monthly basis with intradermal injections of autologous PRFM for 3 months. Changes in hair density will be assessed by comparing pre- and post-treatment photographs and non-invasive measurements of hair density at 1, 2, 3, 4 and 6 months after initial treatment.

Official Title: Enhancing Hair Density With Platelet Rich Fibrin Matrix (PRFM)

Further study details as provided by The New York Eye & Ear Infirmary:

Primary Outcome Measures:
  • Hair Density Change After Three Treatments [ Time Frame: 6 months after initial visit ]
    Hair density index at calibrated distance from glabella in a 2 cm x 2 cm midline square at 6 month follow up visit as a percentage of initial (pre-treatment) hair density index, measured using a proprietary hair densitometer.

Enrollment: 15
Study Start Date: May 2012
Study Completion Date: November 2013
Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment with PRFM
Subjects treated monthly 3 times with intradermal injections of PRFM into bald/balding scalp. Post-treatment hair density index measured and compared to hair density index measured prior to treatment for each subject.
Biological: PRFM treatment
Study participants are treated in the initial visit, and at the 1 and 2 month follow-up visit. 4-8 cc of autologous platelet rich fibrin matrix (PRFM) is isolated from 9-18 cc of peripheral blood. PRFM is then injected intradermally in 0.10 cc aliquots in areas of alopecia for each treatment.
