How Does Laser Hair Removal Work?

A laser is a machine that emits one wavelength of intense light. Some lasers target melanin. These lasers can be used to target the melanin within hair.

The Laser Hair Removal Procedure

A pulse of energy is sent through the laser hair removal hand-piece. Since laser light involves heat to stop the hair follicle from growing again, a cooling system is needed to protect the skin. Sometimes the cooling system is a chilled laser hair removal tip, and sometimes it is in the form of a gel or a spray used during the laser hair removal procedure.
When the laser heat reaches the hair follicle, it deters or stops future hair re-growth of unwanted hair.
Typically, laser hair removal requires 3-5 treatments.
