One of the first questions raised by people considering treatment is: how long doeslaser 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.

How does laser hair removal work?

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 recognises 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.

How long until you see results from laser hair removal?

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.

How long after laser hair removal can I workout?

After treatment it is generally recommended to avoid vigorous exercise and activities that may cause excessive sweating for at least 24 to 48 hours. This is because the treated area may be sensitive, and sweating can potentially irritate the skin or increase the risk of infection.

The treated follicles need time to heal, and engaging in activities that generate heat and sweat can interfere with the recovery process.

It’s important to follow the specific guidelines provided by your sk:n , as they may have different recommendations based on the type of laser used and your individual circ*mstances.
