Why does laser hair removal machine have the best hair removal effect?

The principle of professional laser hair removal machine is to use the characteristics of photon (selective photothermal therapy) to be absorbed by the melanocytes of hair stem and hair follicle, so as to destroy the hair follicle without damaging other normal tissues around.

The growth cycle of hair can be divided into three stages: growth period, transition period and rest period. When the hair is in the growth period, its hair follicle is fully developed, and the hair follicle contains black that determines the hair color. At this time, if the long pulse photon irradiation with a specific wavelength is used, the melanin can be destroyed to achieve the purpose of hair removal of hair follicle atrophy.

Laser hair removal machine at home is mainly used to destroy hair follicles and achieve hair removal effect for growing hair. But generally speaking, the human body’s hair state coexists in three growth cycles. Therefore, in order to achieve the effect of permanent hair removal, it is necessary to receive more than 3 to 5 times of treatment in order to completely destroy the hair in the growth period and achieve the best hair removal effect.
