Long Term (1 Year) Study Of Low Level Laser

Posted on by admin

This study involved a 1 year study of men and women with androgenetic alopecia (male pattern hair loss, MPHL and female pattern hair loss, FPHL).   To date, there had never been a long-term (> 1 year) efficacy of  low lever laser therapy (LLLT) using this population.  This experiment was conducted comparing a laser comb (LDS 100) with a placebo device.  Over a period of 6 months,  240 men with MPHL and 80 women with FPHL were randomized to receive LLLT treatment or placebo treatment. Men and women continued in up to 1 year, placebo controlled extension studies. Efficacy was evaluated by hair counts, patient and investigator assessments, and panel review of clinical photographs.  The results of this treatment sure durable improvements in scalp hair over 1 year (p < 0.001 versus placebo, all endpoints), while treatment with placebo led to progressive hair loss.   The conclusion is that in men with MPHL and in women with FPHL, long-term treatment with LLLT over 1 year was well tolerated, led to durable improvements in scalp hair growth, and slowed the further progression of hair loss that occurred without treatment.
