Hair follicles are capable of producing hair of various thickness and colors.
Dar hair contains the pigment melanin which serves as the target for energy delivered by the laser. The heat build-up caused by the absorption of energy by the hair itself is capable of creating follicular damage and retard to prevent future hair production by the follicle. The application of Ruby or Alexandrite laser energy to the skin results in almost complete removal of all actively growing hairs. The treatment can vary. Part of the difficulty in eradicating unwanted or excess hair lies in the fact that the follicle has tremendous regenerative capabilities and that these recuperative powers are highly variable from individual to individual and from one anatomic site to another.
