How does Laser Hair Removal Work?

Unwanted body hair is a common problem for many men and women but there are a variety of different hair removal methods now available. One of the most effective long-term solutions is laser hair removal which can give smooth, hairless skin within a few weeks. Using laser light energy which penetrates the skin to kill the hair at the root, this procedure undoubtedly achieves longer lasting results than shaving or waxing and a less painful procedure than electrolysis.

The laser hair removal procedure is relatively straightforward; hair must be shaven and cleaned and an anaesthetic cream is applied. The laser then emits pulsed beams of concentrated light which damages the hair follicle, reducing further hair growth. While laser hair removal is generally not regarded as painful, mild discomfort can be expected and skin may become temporarily red or bumpy.


While each person is different, on average 6-12 treatments are required for an effective outcome of 70% to 90% hair reduction. The length of procedure is dependant upon factors such as the size of the area being treated and can range from a couple of minutes to a few hours. While the results of laser hair removal are long lasting, permanent and complete hair removal cannot be guaranteed. Indeed, many patients find it necessary to return for annual laser hair top-up treatments in order to maintain smooth, hairless skin.

It is worth noting that not everybody is the ideal candidate for laser hair removal. Skin type is the main factor in laser hair removal effectiveness, although other genetic issues such as hair type and hair cycle are also important. In recent years there has been a lot of development in laser hair removal and there are now various different types of lasers available. While this means that laser hair removal is becoming more successful amongst darker skin types, particularly Asian and Mediterranean, nonetheless it is undeniable that the best results occur in those with light skin and darker hair.
