A low level laser treatment is not only registered for treating hair loss, but has been proven to help stop hair loss and promote hair growth in both men and women. So, it makes perfect sense to add a laser hair loss product to your treatment if you are wanting to grow more hair. It really is a matter of finding a laser device that best suits your hair loss needs.
Experts agree that a laser hair loss treatment can stimulate resting hairs to grow. Laser treatments can improve existing hair health, promote hair growth and is one of the best hair loss treatments in the world today. People who have undergone a hair transplant also need to use a laser device to improve and strengthen newly transplanted hair follicles. Men who ingest Propecia (a drug we advise against), use low level lasers to stimulate hair follicles from the outside. Women and men who use Minoxidil topically, use laser therapy to improve its effectiveness in hair growth... and the list goes on.
Laser Light Promotes Hair Growth
Low level laser therapy has been around for years. It has been used in dermatology successfully as well as in the treatment of eczema and psoriasis. When low level laser light is focused on the hair follicles, they tend to open up in response and hair growth can be enabled.
Laser treatments work only on live hair follicles and is a long term ongoing hair growth treatment. If you have been progressively losing your hair for many years, chances are some hair follicles may be dead and will not respond to the lasers. Laser treatments work best as soon as people notice thinning hair and hair loss because every time a hair falls out, the hair follicle gets a little smaller, especially if a new hair does not take its place. Laser seems to reverse this process by widening the hair follicles and stimulating them to repair themselves and grow again.
How Does a Laser Hair Loss Treatment Work
Low level laser therapy is a non invasive treatment. A laser device can either be freestanding, or in a cap, helmet or comb with the laser diodes directed at the scalp. The light emitted needs to be in the 630 to 670 nanometer range which is where the colour red occurs on the light spectrum. The power of the light is low wattage, allowing it to remain cool throughout the procedure.
The exposure of the scalp to these tiny laser beams of light is called photobiology, which causes reactions at both a physical and chemical level. Hair follicles, and in particular the very tiny hairs on follicles where hair loss is progressing absorb the laser light. The reaction happens on an intracellular level where an enzyme (cytochrome c) sends photochemical signals throughout the hair follicle. The result is a decrease in apoptosis, or programmed cell death enabling the laser to help stop hair loss and promote hair growth.
Low Level Laser Therapy - Hair Growth or Hair Removal
What is the difference between laser hair growth and laser hair removal? The laser light action is dependent on the total output of the laser wavelength they emit and is not dependent on the number of lasers used to give the output. In fact, if a laser is designed for hair growth, the total laser output has to be in the range of 630 to 670nm (nanometers) with the optimum being 650 to 655nm to be the most effective. For a laser to destroy or remove hair they have to have a higher wavelength output in the visible light spectrum of around 800nm. Lasers used in surgery to remove lesions have to have an even higher wavelength of over 1000nm to work. Just a little higher wavelength than that which is required to work for a specific condition, can actually cause a different reaction, thus the difference between hair growth and hair removal.
