1. INTRODUCTION
Unwanted hair is a major cosmetic problem. Many temporary hair removal methods exist,
including shaving, bleaching, tweezing, cold and hot wax epilation, and chemical depila-
tories (1-3). Only electrolysis has offered the potential for permanent hair removal, but
the technique is tedious, highly operator dependent, and impractical for the treatment of
large numbers of hair (4). Recently, a number of lasers and other light sources have been
developed specifically to target hair follicles. These devices offer the potential for rapid
treatment of large areas and long-lasting hair removal. Physicians and patients alike have
embraced this technology, although published studies assessing the permanency of hair
removal have emerged only recently. With the proliferation of devices targeting hair and
unsubstantiated claims by manufacturers, significant confusion exists in this field. This
chapter will discuss the scientific background of laser hair removal, examine the specifics
of different laser systems, and describe the technique of laser hair removal.
