Hair removal is not limited to women, and now men’s hair removal has begun to be common. Men’s depilation is not as much as women’s depilation, just a few areas. Beard, armpit, chest hair, just abdomen.
The traditional hair pulling and scraping methods can only act on the hair stem and can’t do anything about the hair follicle, so there will be repeated growth. It often needs to be scraped again soon, and improper operation will damage the skin and even folliculitis.
The ingredients used in depilatory cream may cause skin sensitivity, and the effect may not be ideal. The process of wax depilation is unbearable pain for many people.
After experiencing these unsatisfactory hair removal methods, there is finally a new standard of hair removal, laser hair removal.
Principle of laser hair removal
As early as the 1960s, Goldman l described the destructive effect of ruby laser on hair follicle melanin. At that time, this effect was only studied as one of the side effects of laser. Later, in the 1980s, after the principle of selective photothermal effect was put forward, laser hair removal finally became an ideal means to reduce hair clinically.
Laser or strong light hair removal uses the thermal effect of laser to destroy the stem cells, hair follicles and hair nipples of hair follicles, so that the instantaneous temperature of these parts is more than 55 degrees, resulting in the denaturation of proteins in these structures, temporarily or for a long time, affecting the growth function of hair follicles, making hair follicles lose favorable growth conditions and reducing hair.
Because laser hair removal does not destroy hair follicles one by one, but strikes all structures that can absorb wavelengths in the irradiation area, the process is relatively simple, but it is required to avoid omission or repeated irradiation in the operation process, and adjust the energy according to the skin color and hair thickness of different people, Therefore, this is a highly demanding and meticulous work, which tests the operator’s own theoretical knowledge, experience and patience.
