Laser hair removal mainly removes hair in the growth phase, and has no effect on the hair in the resting and developing phases. Hair entering the growth phase is a cyclical process, so laser hair removal must be done 3-5 times to see satisfactory results, but also according to personal circumstances, each person's hair growth condition is different, so the number of times hair growth needs to be removed is also not fixed. Some people can remove it 3 times and keep the lasting effect. Some people with thick hair need 5 or more times. Take it off several times.
