How laser hair reduction works?
Laser hair removal works by sending the light/beams of a laser through the pigment in the hair.
During the procedure, the doctor presses a hand-held laser instrument to your skin. This allows the laser beams to heat up and damage the hair follicles which are located just below the skin. The damage is a part of the treatment only.
These hair follicles are responsible for producing new strands of hair. So, If they are destroyed, the hair production gets temporarily disabled.
So yes, Laser hair reduction does not remove the hair permanently. How many sittings are needed? The treatment works only over a number of sittings at regular intervals. Usually about 6 treatments are needed to achieve approximately 80 percent clearance. Its costs, methods, sitting interval and effectiveness depends on each person's skin type, hair thickness and the area being lasered off. However, it works best on black dark and thick hair. Are there any side effects? Today, laser hair removal is very normal. The number of people having laser hair removal is also increasing. It is safe if you get the treatment done by an experienced and trusted person. However, some people may experience minor side effects after laser hair removal. Tip: You should ask your dermatologist to test how a small patch of skin reacts to the treatment before having it done on a larger area of the skin. How long does the removal last? Six to 12 months While laser hair removal doesn't get rid of hair forever (only electrolysis is FDA-approved for permanent hair removal), it does drastically reduce hair growth—to the point that you can stop shaving altogether. Any regrowth can be managed with touch-up treatments every six to 12 months.
