Laser Hair Removal works by selectively targeting an area using a specific wavelength of light that is absorbed by the melanin, or pigment, in the root of the hair. When the light is absorbed by the pigment it heats up the root and destroys it.
The human hair has 3 different phases of growth;
- Active phase (anagen),
- Resting phase (catagen),
- Shedding phase (telogen).
It is only during the active growth phase that the hair shaft is attached to the root and the root will be destroyed. Each hair moves through the 3 phases of growth over a 6 to 8 week period. This is why Laser Hair Removal necessitates multiple treatments
