How long does laser hair removal last?
11th February 2012
One of the first questions raised by people considering treatment is: how long does laser hair removal last? In short, the length of time needed between treatments will depend on people's skin and hair types. In most cases people will need to undergo six or eight laser sessions to obtain the best results. The duration between treatments will depend on how well the treated area responds.
The lasers used for hair removal work by directing an invisible high concentration light beam into the root of a hair follicle. The process works best with people with lighter skin and darker hair. This is because the laser recognizes melanin which is found near the base of the hair follicle. The lower levels of melanin found in lighter hair and the higher levels of melanin found in darker skin can sometimes make it difficult for the laser to work effectively.
It usually takes around two weeks for treated hairs to be shed, followed by a re-growth phase of four weeks. Therefore treatments are usually set with a month and a half between them. Once six to eight sessions have been completed further sessions are often unnecessary for a few months. However, this depends on how successful the procedure is in removing the hair during the sessions.
Because of the way skin and hair types affect the results it is hard to accurately predict how long hair removal will last. After the initial six to eight sessions, people with lighter skin and darker hair can often wait a number of months before needing a follow up session, but it varies from person to person. If you are considering treatment, consult a technician first to discuss how suitable you are for the procedure.
