One such technique that has become quite popular these days is laser hair removal. This technique works by using a laser on the hair at a specified wavelength that emits a specialized light. The light from the laser is passed through the skin and is absorbed by the hair follicle. This light actually targets the melanin (colour) in the hair follicle and damages it, thereby causing the hair to fall out. Interestingly, the use of certain laser for removing hair has been approved by The Food and Drug Administration (FDA). Although the technique is popular, there are advantages and disadvantages of using this method.
