While performing semi-permanent hair removal procedures, the therapist removes the unwanted body hair from the follicles. You can keep the skin smooth and hair-free for several weeks by waxing or threading the body hair. But the therapist destroys the hair follicles while performing the laser hair removal procedure. Hence, you can get rid of unwanted hair for about two years by getting laser hair removal. Also, the laser light helps the therapist to remove the body hair precisely and immediately.
