Does Low Level Laser Therapy (LLLT) Affect Hair Loss in Men and Women Differently?

Q: Have there been any studies showing the difference between men and women in their response to laser treatments for hair loss?

A: In the International Journal of Cosmetic Surgery and Aesthetic Dermatology (Vol. 5, Number 2; 2003), a study on low level laser therapy (LLLT) was conducted which indicated that there was a 55% increase of growth (hair count) in the temporal area as well as 64% in the vertex of the female subjects who were treated with LLLT for hair loss. The study also indicated a 74% increase in the hair counts of the male subjects in the temporal area and 120% in the vertex region. These results would initially indicate that LLLT works better in men than in women, but there were four times as many men in this study so the results might be different in a larger test group.
