TLDR Laser hair removal is now more effective, but the best treatment schedule is still uncertain.
The document discussed the mechanisms, efficacy, and clinical considerations of various laser hair removal technologies available as of 2004. It explained that effective laser hair removal targets hair follicles during the anagen phase and requires appropriate wavelength selection based on skin type and hair color. The document reviewed several laser systems, including Q-switched Nd:YAG, long-pulsed ruby, alexandrite, semiconductor diode lasers, and intense pulsed light, highlighting their specific applications and effectiveness. Complications such as hyperpigmentation and hypopigmentation were noted, with most side effects being temporary. The evolution of these technologies had improved clinical outcomes, making long-term hair removal achievable for most individuals.
