Many people have switched to laser hair removal for getting rid of unwanted hair because it’s a more permanent solution. But how do lasers eliminate excess hair, and does laser hair removal completely remove the hair follicle.
Laser Hair Removal
Laser hair removal is a convenient way to get rid of unwanted hair on the face and body. Commonly treated areas include the face, legs, underarm, and bikini line. Traditional alternatives such as tweezing, waxing, and plucking provide only temporary results, and are also time-consuming and painful.
There are many types of cosmetic lasers now being used for hair removal, and the choice will depend on your hair and skin type. Treatment time ranges from 20-60 minutes, and varies based on the size of the area being treated.
It may take up to 4-8 treatments to obtain the desired hair reduction. Multiple treatments are necessary in order to accommodate the growth cycles of the hair. Hair grows in cycles, and the laser is only able to impact hair when it is in the anagen or active growth phase.
How does it work?
The laser emits a specific wavelength of light that penetrates the hair follicle. The energy is converted into heat, and is absorbed by the melanin (pigment) that is present in the hair follicle.
Does laser hair removal completely remove the hair follicle?
The laser action damages the hair follicle and inhibits further growth. Laser hair removal will destroy the follicle at the root, but it will not completely remove it.
