Researchers from the Harvard Medical School surveyed five clinical studies designed to measure the effects of low-level light laser therapy (LLLT) on androgenic alopecia in both men and women. In each case, they found that red and near-infrared LLLT was a safe and effective treatment option for both men and women with genetic balding.
A recent study published in the journal of Lasers in Surgery and Medicine tested both the safety and effectiveness of a low-level laser therapy device in a randomized, blinded, controlled study and found that laser light in the 655nm range significantly promoted hair growth in male patients with androgenic alopecia.
Given the large number of people who are affected by androgenetic alopecia and for whom traditional treatments, like surgical hair restoration or hair loss medications, may not be indicated, could low-level laser therapy be a viable and effective treatment option? New research published this year, 2014, in the American Journal of Clinical Dermatology, says yes.
The significance of these results is that it documents the ability of laser light to stimulate hair growth in vitro. The results showed that laser energy stimulated proliferation of cells in the hair matrix.
