Hair loss treatment with low level laser light therapy can be traced back to 1964 when Professor Andre Mester of Budapest conducted an experiment using low level laser light rays to heal the wounds of laboratory mice. He discovered that the laser rays stimulated blood circulation and caused hair located in the area of the wound to grow thicker and longer.
Low level laser light therapy is now widely used around the world as a treatment for hair loss. Laser light rays are applied directly to the scalp and penetrate deeply to activate blood circulation around the hair follicles, halting hair loss and stimulating new growth.
Until recently, this treatment was only available under medical supervision in clinics and was very costly, but the miniaturisation of the technology and stringent, international safety and quality requirements have led to the exciting development of affordable hand-held hair loss treatment lasers for personal use at home.
What Type Of Hair Laser Will Be Most Effective?
Currently there are many different types of hair laser available on the market but how do you choose which is going to be the most effective in treating your hair loss?
Each different laser light used in hair loss treatment lasers has a specific treatment and penetration depth into the scalp. The blood capillaries in direct contact with the dermal papillae lie in the hypodermis, the deepest inner layer among 3 layers of skin (scalp) tissue. The dermal papillae nourish the hair follicles and play a pivotal role in the cycle of hair formation and growth.
Does the Wavelength of the Lasers Matter?
Lasers around the 650nm / 670nm wavelength are the most commonly used in hair loss treatment lasers since their light is a clear, bright red which is immediately visible to the naked eye. It is easily observed to be working in treatment and in fact, it actually does have a beneficial therapeutic effect. They are also cheaper to use in manufacture than longer wavelength, infrared lasers. However, light at this wavelength mainly treats the surface of the scalp and does not penetrate deeply enough so, used alone, is not sufficient for effective hair loss treatment.
The more expensive infrared (invisible light) lasers which use 780nm wavelength are able to penetrate and energise deeper within the skin tissue and are more effective in treatment, although substances within the skin tissue such as melanin, water and haemoglobin absorb and weaken the energy of the laser light. Due to their cost, these lasers are rarely used by manufacturers of hair loss treatment lasers.
Laser light at 830nm wavelength is the least absorbed by the melanin, water and haemoglobin in the skin tissue and therefore able to retain more of its beneficial power to energise the hair follicles and so more light energy can be absorbed into the blood cells. This increases blood circulation and the delivery of nutrients and oxygen to the hair follicles.
Multi Wavelength Hair Loss Treatment Lasers
The most effective hair loss treatment lasers use a combination of 670nm, 780nm and 830nm lasers, such as the Wellay Personal Hair Laser which uses 21 low power multi-wavelength lasers, in 7 groups of 3 lasers at 670nm, 780nm and 830nm. The 3 different wavelengths irradiate the same area of the scalp simultaneously, each working at different layers of the tissue, maximising the benefit and proving a more effective hair growth treatment.
In clinical trials, regular treatment with a Wellay Personal Hair Laser stops the progress of hair loss in 85% of users, increases blood supply to the scalp by 54% after only one treatment, stimulates hair follicles to activate re-growth and improves the quality of the hair shaft resulting in a 25% increase in hair volume and shinier and thicker hair. It also gives noticeable hair growth in as little as 12 weeks. With continuing use, the hair will carry on growing and improving in health.
Patented Technology
The Wellay Personal Hair Laser from beauty-lasers uses world-first patented technology and is the only genuine multi-wavelength hair treatment laser for home treatment of hair loss and scalp conditions. It has CE approval, ISO 9001, ISO 14001, and ISO 13485 and FDA (Korea) approval. It has been designed to the highest international safety and quality standards.
There are many scientific studies for each laser wavelength that show how effective it is in therapeutic treatment - you can read more about the different effects of each wavelength on the website of the Swedish Laser Medical Society.
