How long can laser hair removal last?

Time : 2021-04-02 Hits : 5

Laser hair removal is a long-lasting method of hair removal that “destroy” hair follicles. But it does not mean that the hair will not grow anymore. The hair in the hair follicle will grow again after some time since the laser hair removal is done. Therefore, many doctors now regard laser hair removal as long-lasting hair removal rather than permanent hair removal.

What is the principle of laser hair removal?
Laser hair removal is the use of lasers to align the pigments of each hair. The laser can reach the root and enters the hair follicle. The heat generated by the laser will destroy the hair follicles, and the hair will stop growing. Hair follows a unique growth cycle, including dormancy, degenerate, and growth periods. The hair in the dormant phase cannot be recognized by the laser. Therefore, if we want to do hair removal totally, we have to wait for the hair to back to the growing phase.

2. How long can it last after laser hair removal?

After laser hair removal is completed, the hair will grow out again after a period of time. The duration of the hair removal effect varies from person to person. The metabolism is faster and the hair follicles recover more quickly, so that hair will grow in shorter time again. The effective period of hair removal for such people is about 1 year. For people with slow metabolism, it may take 3-5 years.
