Worried about unwanted hair and dreading the upcoming waxing appointment? Depilation, or hair removal, is traditionally done by waxing, hair-removal creams, or shaving. While waxing can be painful and uncomfortable, shaving is pain-free. However, both methods are temporary. If you’re on the lookout for a semi-permanent method, the ideal solution is laser hair removal.

The Depilatory Effects Of Laser Hair Removal

The process of laser hair removal involves exposure to controlled pulses of laser energy directed at the hair follicles. The principle of laser hair removal is selective photothermolysis (SPTL), wherein the hair follicle is selectively heated until it is damaged.

Melanin, the chromophore that decides the intensity of hair color, is present in the hair follicle. Light is readily absorbed by dark-colored substances like melanin. By matching the laser’s wavelength and pulse duration to the melanin, only the targeted follicles are affected without damaging the surrounding area.

With repeated exposure and follicle disruption, hair density in the treated region is significantly reduced. Hair goes through growth phases, and when hair is in the correct phase, it is able to be targeted for removal.
