Laser hair removal is a safe and effective way of removing undesired hair from the body. Laser hair removal works by directing a focused infrared light pulse through the skin to where it heats up and destroys hair follicles.
Hair grows in cycles: Hair grows out from hair follicles that are found throughout the outer layer of the skin. There are three phases of hair growth. The growing phase (called anagen) is when hair is actively being produced. Laser destruction of the follicle works for hair in the growing phase. Hair may then go from the actively growing phase into a brief changing stage (called catagen) where the bottom of the follicle is absorbed into the body. Lastly, the hair follicle enters the resting phase (called telogen) where no active hair growth occurs. Hairs that remain in the follicle may eventually fall out or get pushed out by a new hair growing when the hair follicles enters the growing phase again.
