Laser hair removal works by targeting the dark hair follicle underneath the skin. The lasers are designed to omit the color of the skin and only target the dark pigmented hair. The light/heat absorbed by the follicle stuns the growth of the hair. After each treatment, the hair grows back thinner and finer and some hairs are permanently removed.

For Laser Hair Removal to work the treatment should be performed during the Active (Anogen) Growth Phase which is about every 6-10 weeks depending on the area. Facial hairs grow faster than body hair. Facial treatments are often repeated every 4-6 weeks. Body hair is treated every 8-12 weeks depending on the number of treatments the individual has had.

The pain associated with laser depends on how thick and how dark the hair is. The more hair that is needed to treat, more heat is generated in the area hence causing more pain.
