Laser hair removal works by sending light into the hair follicle via laser, which is absorbed by the pigment, or melanin, in the hair — this is why it originally worked best on people with darker hair.

When the light is absorbed by the pigment, it’s converted to heat, which is what actually damages the follicle.

​

After the laser damages the hair follicle, the hair vaporizes, and a full round of treatments later the hair will stop growing back.

Laser hair removal may help prevent ingrown hairs and will save time typically spent waxing or shaving.
