Is Laser Hair Removal Permanent?

Laser hair removal can be considered “permanent reduction”.

It permanently disables hair re growth as long as the right type of hair is treated with an appropriate type of laser at effective settings.

It is called a “reduction” because lasers used for hair removal cannot and do not remove 100% of the hair in any area. With proper treatments laser can remove the majority of the coarse hair on a body area but they cannot remove finer hair.

Results may vary due to a number of factors such as type of laser used, how settings are set, underlying cause of the hair growth and the practitioners experience etc.   It is important to realise the body can also develop new hair growth due to numerous factors such as age, stress, diet hormonal changes and certain medical conditions.

Generally a patient can tell how much reduction has been achieved from a course of treatments after waiting 6-12 months from their last treatment. Patients who experience new growth in later life may benefit from “top-up” sessions.

Expected outcome can be difficult to predict and there is always the possibility that certain individuals may fail to respond to treatment.
