Laser hair removal is a safe, fast, and more effective procedure to eliminate unwanted hair than electrolysis, waxing, or tweezing. The primary principle behind laser hair removal is selective photothermolysis. This means that the laser selectively heats the area that causes hair growth (the follicle), with little or no damage to the surrounding skin. Laser hair removal works on individual hair follicles during their growth cycle to deliver consistent, lasting results regardless of skin color or body area. Few sessions of laser treatments (within a time period apart) are required to eliminate unwanted hair.With the latest laser devices (Alexandrite laser) hair removal is a painless procedure. The number of treatment that are required depends on the skin colour and hair colour.
