During an ICON® laser hair removal procedure, hairs are targeted with an intense beam of light, that degrades the hair at the root. Hairs that have been lasered will often return after three to four months but will be much lighter than in the past. After so many sessions, the hair may not return at all. Hair removal procedures can last anywhere from 30 to 60 minutes, depending on the size of the targeted area. Because the energy waves are aimed directly at the hair itself, no other tissues are affected. ICON® laser hair removal procedures are non-invasive and produce very few side effects. During a hair removal session, the patient does not need any anesthetic or other types of sedation.
Laser hair removal treatments can show a dramatic reduction in the coarseness and color of a hair after only one treatment. Lighter hairs will be the first to be eliminated. Hairs that are coarse and dark may require several treatments before they begin to lighten and appear less coarse and rigid. While complete hair loss cannot be guaranteed, laser hair removal treatments can provide lighter, finer hair after two or three treatments. The rate at which the hair grows back will depend on the hair itself, as well as the patient. Each patient will respond to the treatment differently causing the hair to return much slower in some cases, with no hair growth in others.
With most laser hair removal procedures, the hair will eventually grow back, especially if it is very dark and coarse. The lighter and finer the hair that is being treated, the longer it may be before it returns. In some cases, the hair may become so fine that it eventually stops returning, although this is not always the case with the darker hairs. With lighter colored hair, it may take up to five or six weeks for it to begin to grow. Dark, coarser hair may begin to grow after just three to four weeks. Each person is different. If a person's hair and fingernails grow extremely fast, their body hair will also grow at an accelerated rate. Those who have slow growing nails and hair, may have body hair that grows slowly.
