Outdated Hair Laser

In 1997 a European group of scientist's published their work on LLLT in the treatment of alopecia of the scalp. The authors tried to verify the efficacy of low energy laser (LLLT) in scalp alopecia. Sixty patients were divided in two groups: A) laser group, 33 patients treated with both LLLT and classical therapy; B) control group, 27 patients treated only with classical therapy, Before, during and after treatment, historical samples were done.

For the group A the results were rather superior but in a twice shorter time shorter time than group B. The maintenance of the good results needed classical therapy for a long period. They conclude that LLLT therapy could have a useful complementary method for the treatment of scalp alopecia.

The same European group of scientist's published their findings on LLLT use in the treatment of alopecia and crural ulcers in 1998. The authors tried to verify the efficacy of LLLT in scalp alopecia and crural ulcers of different causes. Laser used was (red diode, continuous emission, 8 mW power, wave length 670 nm spot size about 5 mm diameter on some points. They also use as control classical therapy. Before, during and after treatment, histological samples were taken from alopecia regions. For the laser groups (alopecia and ulcers) the results were rather superior and in a three or twice time shorter than the control group. They conclude that LLLT therapy is a very useful complementary method for the treatment of scalp alopecia and crural ulcers
