Various light sources, including light Emitting Diodes (LEDs), have been used in attempts to grow hair and stop hair loss since the 1950's. The LED was placed 30 centimeters from the alopecia area with dosages ranging from 3-4 joule per sq.cm. No fibers or lenses were used. In the study, microscopic evaluation of the hair shaft structure on the Alopecia Areata exposed areas showed a clear medulla rich in keratin after treatment.
The Bennis Orbit Light has no heating effects, no damage to the skin and no known side effects. Rather, Bennis Orbit Light directs biostimulative light energy to the body's cells, which the cells then convert into chemical energy to promote healthy rejuvenation of hair.
At the 4th Annual Meeting of the Japan Light Therapy Association in 2002, success was reported with an increase in both hair growth and density of the hair follicles in the light treated areas of both male and female stress Alopecia and Alopecia Areata. Only one failure out of 240 cases was reported in two papers.
In a double-blind comparative study of light treatment, the duration of hair loss and baldness, according to Hamilton classification, were recorded. A skin biopsy for histological examination was taken before and after treatment. In addition, a photograph was taken of the patients at the same time. Hair shaft thickness was measured with hair stretching equipment where the hairs can be stretched on a graded scale from 0-10. Normal value of hair shaft stretching is set at 5.
All 240 patients with the exception of one, in the light treated group showed a complete stop of hair loss. All patients, except 3 showed a clear regrowth of hair with a reduction of at least one category in the Hamilton classification. The results were confirmed by histological examination. Pre-treatment typically showed the dermas with large, relatively normal amounts of follicles. Most of them were in the Telogen Phase and did not show any real hair. Some of the follicles were widened with keratin taps and follicle opening, post treatment showed the dermis with almost the same amount of hair follicles as pre-treatment, although a number of new follicles could be seen with clearly noticeable hair growth. 50% of the follicles are now in the Anagen Phase.
A clearly visible regrowth of hairs was found in most treatment sample comparisons when comparing the histological findings, transformation into more Agnogenic hair follicles could be observed in 83% of the patients on light treatment but in none of the placebo patients. Out of the 240 patients, 14 showed an increase in hair thickness, and all 240 showed improvement in general hair shaft quality measured with the hair stretcher. The present double-blind study definitely showed that regrowth of new hairs can be achieved in most middle-aged and younger males and females, with typical male and female baldness when the scalp is exposed to Light Therapy for 30 minute twice weekly for 10 weeks.
Material for the growth of the hair comes from the papilla. As long as the papilla is not destroyed, the hair will grow. If the hair is pulled out from the roots, it will nevertheless grow again. Should the papilla be destroyed, it will never grow again.
