Laser hair removal targets hair follicles using concentrated light energy (laser technology). The laser emits a wavelength that is absorbed by the melanin (pigment) in the hair, which then converts to heat. This destroys the follicle while preserving surrounding skin, preventing future hair growth.
Hair grows in three phases:
Anagen (Active Growth Phase): Hair is attached to the follicle and contains melanin, making it the best phase for laser treatment.
Catagen (Transitional Phase): The follicle shrinks, and hair begins to detach, making it less responsive to laser therapy.
Telogen (Resting Phase): The hair sheds, and the follicle remains dormant before restarting the cycle.
Note: Since not all hairs are in the same phase at once, multiple sessions are needed to target hairs in the anagen phase for optimal results.
