Laser hair removal generally takes three to six times, mainly due to two factors:
First, most hair follicles are tied together in groups of three and open in the same pores. A hair in the pores is the hair growing from one of the three hair follicles in the group below it. Therefore, one treatment can only destroy one hair follicle in a group;
