Laser hair regrowth treatments

The Principle of Low Level Laser Therapy or photo-biotherapy is as old as sunlight itself. Harnessing and refining the therapy with low reactive laser, like LaserTek 9000, is relatively new. Low level lasers are “soft” lasers, often referred to as “cold” lasers, and do not have the thermal-component to cut, burn or vaporize tissue. Low level laser therapy (LLLT) is based on the scientific principal of photo biotherapy. Photo-biotherapy occurs when laser light is absorbed by cells stimulating cell metabolism and causing damaged cells to repair themselves. Photo-biochemical changes in cells can only be achieved with the correct amount of light energy, delivered at the appropriate wavelength. According to laser researcher, Dr. David G. Williams, “Low Level Laser Therapy, or LLLT, is a miraculous healing tool.

Laser Light Energy Explained

Normal white light produces a thermal effect in the skin. This is due to its relatively high-energy output, with a large share of its light in the infrared spectrum being absorbed by the water in the outer cell structures. Laser light, with one specific wavelength, penetrates deep into the layers of skin and is absorbed, provoking a photo-biochemical chain reaction. The Laser Hair Therapy 9000 device has 50 diode lasers mounted in a half sphere, delivering laser energy to the tissues of the scalp. Laser energy (photons), penetrate deep into these tissues and are absorbed by deeper cell structures, resulting in a photo-biochemical chain of cellular and sub-cellular events. Laser Hair Therapy 9000 is clinically proven in European studies to stimulate these cellular and sub-cellular events, leading to a dramatic increase in micro-circulation of blood supplies, cessation of hair loss and stimulation of hair re-growth. Various light sources including lasers have been used in attempts to stimulate hair growth and stop the progression of hair loss since the 1950’s.

• In 1969, Dr. Brian E. Johnson reported his attempts to stimulate hair growth in C57B mice by 260 nm irradiation. Inhibitions were reported in the wavelength range 280-310 nm.

• Professor E. Mester reported in 1968 that unfocused 694 nm Rubin laser-light initially increased hair growth in C57B mice.

• In 1984 Dr. Trelles showed in one study that patients with alopecia areata who were treated with HeNe Laser 632.8 nm 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 four weeks. The HeNe laser 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 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 4th 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.
