Study proves that laser energy stimulates the growth of hair ex-vivo

BOCA RATON, FL – First of a kind data from a study conducted by Laboratoire Bio-EC, Paris France on the on ex-vivo growth of hair from Low Level Laser Light exposure of hair follicles maintained in Philpott hair culture medium were presented at the 17th Annual Meeting of the International Society of Hair Restoration Surgeons (ISHRS) by Dr. Michael Hamblin.

Michael Hamblin, PhD, Associate Professor, Harvard Medical School/Wellman Center for Photomedicine, Massachusetts General Hospital, is one of the foremost researchers in the field of Low Level Light Therapy (LLLT) and Photodynamic Therapy. He presented important data from this study which compared a dose of laser energy and a reference dose on the ex-vivo growth of hair to show that laser energy stimulated hair growth. Isolated follicles were placed in the Philpott hair culture medium, exposed to the laser doses, and measured for hair length increases. Analysis of hairs grown ex-vivo exposed to the two laser doses, were photographed at regular intervals over ten days.

The conclusion of the study was that the wave length dose studied induced statistically significant ex-vivo increase in hair growth vs. control dose at the conclusion of the study.

This significance of these results is that for the first time a study has documented ex-vivo hair growth in isolated hairs using laser stimulation. The results conclusively indicated that laser energy stimulated proliferation in the hair matrix. This is the first time that data has been presented at a medical conference showing positive reaction on ex-vivo hair growth from laser energy exposure.
