Low-Level Laser Therapy is Now a Do-It-Yourself Hair Loss Treatment
 |
The effectiveness of low-level laser light in hair restoration was described today in a presentation at the 11th Annual Meeting of the International Society of Hair Restoration Surgery (ISHRS). The ISHRS is meeting October 15-19, 2003, at the Marriott Marquis Hotel, New York City.
Excerpts of the ISHRS 2003 Press Release on LLLT
NEW YORK (October 16, 2003) - While lasers are best known as high-energy beams of coherent light that can cut through a variety of materials including human tissue, low-energy laser light has been found to be capable of modulating beneficial biologic effects in human, animal and plant cells.
Low-level laser light has also been found to have biomodulating effects on human hair and hair follicles.
Clinical studies have shown that low-level laser light is effective both cosmetically and physiologically in hair restoration. The cosmetic effects include improvements in hair sheen and strength, characteristics that enhance the perception of "fullness" in overall hair appearance. Physiologic effects on hair follicles observed in both men and women include (1) prevention of hair loss, and (2) stimulation of hair regrowth in areas of hair loss.
In clinical trials, 97% of patients have had some benefit in improvement of hair characteristics, stabilization of hair loss, or hair regrowth
In the most recently conducted FDA clinical trials of the device, patients studied were men and women with thinning hair in the scalp area. The patients received two low-level laser light treatments per week over a six-month period. Results have shown:
- 100% of men had stabilization of hair loss in frontal and vertex (top of the head) areas;
- 84.6% of men had hair regrowth (11% of more from baseline) in the frontal area;
- 82.8% of men had hair regrowth (11% or more from baseline) in the vertex area;
- 87.5% of women had stabilization of hair loss in the frontal area;
- 100% of women had stabilization of hair loss in the vertex area;
- 75% of women had hair regrowth (11% or more from baseline) in the frontal area; and,
- 96.4% of women had hair regrowth (11% or more from baseline) in the vertex area.
No side effects of low-level laser therapy have been observed. There have been no reports of eye damage from exposure to low-level laser light.
The ISHRS is the world's largest not-for-profit professional organization in the field of hair restoration surgery, with 512 physician members in 45 countries. The organization was founded in 1992 to promote the enhancement of the specialty of hair restoration surgery through education, information-sharing, and observance of ethical standards.
