Laser hair removal offers the best combination of effective hair reduction and minimal fuss, but while it is quite effective, it is not completely permanent. Instead, laser hair removal can result in a reduction of up to 90% of hair growth on the treated area. It is a simple, uncomplicated treatment that involves applying laser or pulsed light to your hair follicles which gently heats the follicle until the it is incapable of growing new hair. Originally this worked best on a combination of light skin and coarse dark hair, because the dark hair was better at turning light into heat, but newer laser light technology works for all skin and hair types.
The reason laser hair removal is not completely permanent is because of the way human hair grows, and the healing power of the human body. There are several cycles of hair growth – active, regressive, and resting – and any hairs in the resting or regressive cycle are not developed enough for the laser to affect them. This is why several treatments are often necessary to achieve the results you want, because otherwise hairs in the resting cycle will move into the active cycle and start growing again. Luckily, you can avoid this problem by just returning for the next round of treatments, until all of the hairs follicles have been treated.
