The hair growth is driven by the protein in the hair roots. The diode laser destroys those protein molecules of the hair root, so that the necessary nutrients for hair growth can no longer be formed. This is the underlying principle of all permanent hair removal methods with laser.
The specific wavelength of the light waves of the diode laser is 808 nm and is therefore optimally suitable for the gentle transferring the laser energy into the hair roots. There the laser energy is converted into heat. The treatment is done by moving the handpiece over the body. Whereas the laser emits its bundled light waves.
The laser warms up the hair roots and denatures the protein, responsible for the hair growth. Since the hair follicle no longer receives the nutrients, necessary for the hair growth, the hair falls out permanently.
The diode laser has another advantage: the laser energy only affects areas of the skin where hair papillae are located. The surrounding skin areas and tissue and also the haemoglobin in the blood is not affected.
