Laser hair removal does it work
The essence of the method of laser hair removal is that the laser beam affects the pigment melanin, which is contained in the hair follicle and hair shaft.
Equipment-laser light source generates a momentum that carries the infrared light and heat. Flash itself lasts a split second, but this time is enough to warm up the structure of the hair bulb and died. In this case, the hair shaft is heated first, it conducts heat to the site growing zone of the follicle. The process of destruction of hair under the influence of heat is called photothermolysis. Similarly, one can eliminate visible hair on the skin. But we must remember that in human skin hair follicles provisions laid at rest.

After six - eight weeks "dormant" follicles are activated, the skin will be a second "wave" of hair - and laser hair removal procedure must be repeated. A distinctive feature of laser hair removal is that it is, except for the death of the "active" hair follicles, causing further weakening and "dormant". After two or three notes session patient not only reduce the amount of hair, but also change their color and texture (the hair becomes thinner and lighter).

During the procedure of laser hair removal laser flash parameters must be selected taking into account the different thermal sensitivity of hair and skin, as well as their different saturation melanin.
A special combination of duration and frequency of the pulses provides almost instant heating rod and hair follicles. In skin thermal relaxation time is less so for the outbreak, it is only slightly warm. That is, laser hair removal is selective to the hair without damaging the epidermis. This procedure allows for the most sensitive parts of the body - in the bikini area, face and armpits.
The energy of the light flux at a constant wavelength reaches the level of the skin where the hair follicles and does not penetrate further, respectively, subcutaneous tissue.
