Hair Removal Using an Nd:YAG Laser System

The document from 1999 explores the use of Nd:YAG laser systems for hair removal, detailing the laser's function, targeting of hair follicles, and considerations for effective treatment. It discusses the importance of targeting the lower third of the follicle and the potential location of follicular stem cells. The Nd:YAG laser's 1064 nm wavelength allows for deep penetration and reduced side effects, making it suitable for various skin types. Clinical studies are reviewed, including an initial study with 64 subjects showing a 50% to 60% hair reduction at 12 weeks, and subsequent studies with varying results. The document notes that multiple treatments are often required, and while permanent hair removal is possible, it is not guaranteed. It also discusses the potential for longer-lasting hair reduction with future improvements in chromophore distribution and pulse technology. The document does not provide specific numbers for all studies mentioned, but it does highlight the safety and practicality of the Nd:YAG laser for hair removal across different skin types.
