What are the disadvantages of traditional laser hair removal?

At present, the search on the Internet has no shortcomings.

First of all, let's understand the principle of laser hair removal. Pulsed light with controllable and appropriate energy is absorbed by the hair follicle tissue, which accurately destroys two important components in the hair follicle, namely, the hairline and the papilla. Through the use of broad-spectrum technology, mild and non-invasive treatment is provided. The intense pulsed light energy with special wave band penetrates the skin and reaches the deep part of the hair follicle, so that the temperature of the hair follicle rises rapidly until it solidifies and dies, thus achieving the effect of permanent hair removal.

Is the effect of laser hair removal permanent? Laser hair removal technology has been certified, which can maintain the permanent removal effect of growing hair after several cures, and the specific number of cures is related to many factors such as skin and hair quality. Laser hair removal usually takes three to five times, and some people even need more times, because the hair growth cycle has three stages: growth period, regression period and rest period, and only the hair in the growth period can be effectively removed. These three growth cycles of hair exist at the same time, so it takes several courses to achieve a more thorough hair removal.
