This early summary of laser hair removal primarily discusses hair physiology, with a very brief summary of preliminary findings with ruby and Nd:YAG lasers. Dr. Chernoff, who now prefers the term "laser hair modification," states of rubies: "Pulsed width proved to be a critical factor as only 15 to 20% of incident light at 700 nanometers penetrates through a 3 mm. thick dermis." This fundamental problem shows the limitations of ruby lasers for especially deep or coarse hairs.
