In the process of laser hair removal, a concentrated beam of light which is called laser is used to remove unwanted hair. In the medical process of laser hair removal, the laser emits a light that is received by the melanin in the hair. The light energy changes to heat and this heat can damage hair follicles that produce hair. This damage stops or delays the hair to grow in the future.
It should be noted that laser hair removal can only delay the growth of hair, but the result is not permanent. If you want the result to last for a longer time, you may need to repeat the treatment a couple of times. Laser hair removal can work successfully on all types of hair, but it is more effective for those with light skin and dark hair.
Why is it done?
The need for not having unwanted hair and being tired of shaving it, again and again, make people have the laser hair removal treatment. The common locations to have such treatment are legs, upper lip, armpits, bikini line, and chin. It is not possible to have laser hair removal for the eyelid and the surrounding area, but it is nearly possible for all other parts of the body to have this medical treatment. Moreover, skin with tattoos is not supposed to be treated.
The success of laser hair removal depends on hair colour and skin type. It is very important that the pigment of the hair not the pigment of the skin absorb the light. The laser should damage only the hair follicle, and it should not damage the skin. S having dark hair and light skin can make great colour contrast so that it would lead to an outstanding result.
When the skin is darker the risk of damaging it would be higher, but thanks to technology these days’ laser hair removal for people with dark skin can have an acceptable result, too. Moreover, people with grey, white, red, and blond hair may not experience a great result in laser hair removal because their hair does not absorb light well.
What are the risks of laser hair removal?
The risk of side effects of laser hair removal depends on many factors such as skin type, hair colour, treatment plan, and adherence to pre-treatment and post-treatment care. The most common side effects of hair removal are:
