• In 1964, Professor Andre Mester from Budapest, Hungary, began experimenting with the use of low-powered laser energy. In 1968 Professor Mester reported rapid healing of wounds in mice due to microcirculation of blood supply. This healing was also noticed in laser hair rejuvenation treatment of diabetic patients suffering with dystrophic sores.
• In 1969, Dr. Brian E. Johnson reported his attempts to stimulate hair growth in mice.
• By 1984, Dr. Trelles showed in one study that patients with alopecia areata who were treated with laser showed a good response. Dr. Trelles reported that most of the patients with alopecia areata responded well after only 6 to 8 treatments administered twice a week for 4 weeks. In the same study microscopic evaluation of the hair shaft structure on the alopecia areata irradiated areas showed a clear modulla rich in Keratin after treatment.
• At the fourth annual meeting of the Japan Laser Therapy Association in 1992, success was reported either an increase in both hair growth and the density of the hair follicle in the laser treated areas of both male and female stress alopecia and alopecia areata patients, with only one failure out of 40 cases reported in two papers.

Two clinical double blind controlled studies have been completed on Laser Hair Therapy 9000.

• Cessation of hair loss, increased re-growth of hair with improved hair quality
• Increased circulation in scalp blood flow.

The results of these clinical studies are to be published in scientific journals.

Hair Loss, Re-growth (Study #1)

A double blind comparative study of laser treatments with placebo laser (LED)5 for treatment of Hereditary Alopecia in young males. Abstract: A double blind placebo controlled study was carried out to evaluate the effect of laser therapy by comparing Laser Hair Therapy 9000 (InGsAI, 670 nm) and a placebo laser (LED). 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 patient 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 the hair shaft being 0.5.

Hamilton Classification Chart

The results were confirmed by histological examination. All patients with the exception of one in the laser-treated group showed a complete cessation of hair loss. All patients except 3, showed a clear re-growth of hair with a reduction of at least one category in the Hamilton classification. Pre-treatment typically showed the dermis with large, relatively normal amounts of follicles. Most of them were in the telogenphase and did not show any real hair. Some of the follicles were widened with keratin taps at the 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 were now in the anagen phase. A clearly visible re-growth of hair was found in post treatment sample comparison. When comparing the histological findings, transformation into more angenic hair follicles could be observed in 83% of the patients on laser treatment, but in none of the placebo patients.

Out of 18 patients, 14 showed an increase in hair thickness, and all 18 patients showed improvement in general hair shaft quality. When measured with the hair stretcher, the results sowed no improvement in the placebo group or any adverse effects of the treatment. The present double blind study definitely showed that re-growth of new hair can be achieved in most middle-aged and younger males, with typical male pattern baldness, when the scalp is irradiated with Laser Hair Therapy 9000 for 15 minutes twice weekly for 5 weeks, with follow-up maintenance treatment.
