Hair removal is one of the oldest element of beauty treatments. Shaving was the oldest way to get rid of excess unwanted hair. Then came the salon treatments like waxing and threading. Some chemical creams that dissolve hair shaft are used as depilatory creams. All these give temporary relief from hair growth. Shaving leaves behind thick hair stubs that gives a rough look while threading and waxing can induce follicular damage. Depilatory creams can cause contact allergy. The real revolution in hair removal came with advent of lasers and light. The initial enthusiasm believed that hair removal with laser and light is permanent. The first company who got patent for IPL hair removal marketed that as complete hair removal within three sessions though they believed that to be one session. The company got bankrupt after hundreds of lawsuits who didn't get hair removal after three session. Then the word laser hair removal was replaced with hair reduction. Now it is no more 'permanent'. Now 'long term hair reduction' is the technically correct term. What are the scientific facts? First, laser can treat thick and black hair shafts and NOT thin and pale hair. Second, there is no need of removal of fine less visible hair. Most of laser physicians now believe that laser should be used only in thick hair and complete removal of all the hair shafts is not desired.
