Are you wondering how laser hair removal work? Read on to understand how exactly the hair removal process works.
Laser hair removal treatment is a procedure that uses a concentrated beam of light (laser) to remove unsolicited hair.
Laser hair removal works because the light of the laser beam is changed into heat. The laser light is attracted to the color in the hair. The dark pigment absorbs heat and converts it to heat. That heat is used to damage hair roots that produce hair. This damage inhibits the growth of hair in the future.

The thicker and shadier the hair is, the more pigment there is. That is why it is not advisable to wax or pluck hair before the treatment. This is because when there is no hair, there is less pigment to attract the laser light. Therefore, treating the hair follicle will be impossible.
Before the laser hair treatment procedure, a medical professional cleans the treatment area. For the particularly sensitive areas, a numbing gel is applied to reduce the discomfort. During the process, everyone in the room has to wear special protective eyewear. This prevents the eyes from the damage of the laser light.
Once the numbing gel has done its work, the medical professional concentrates a beam of high-energy light at the area to be lasered. If the area to be treated is bigger, the longer the procedure takes. Small areas can take as little as 20 minutes while larger areas such as the chest can take an hour or more.

Laser hair removal is not painful. Some patients say it’s like a sensation similar to a rubber band snapping or a sunburn-like sting. As the hair vaporizes from the energy of the laser, there can be a reeking smell from the smoke puffs.
Several laser hair removal treatments are required for primary hair removal, and maintenance treatments might be needed as well.
