Excess hair or unwanted growth of hair on certain body parts is a frequent concern in women. However, with increasing preference for a “neat image” among men, the number of male hair removal treatments has grown considerably. Traditional methods of hair removal, like shaving, waxing, chemical depilation, or electrolysis, have been shown to be ineffective over the long term and can be slow, uncomfortable, and impractical. Due to its superior long-term outcomes in hair reduction, laser and light-based hair removal technology has grown at one of the quickest rates in the cosmetology industry over the last 20 years. Manufacturers and practitioners have been compelled to look for safer and more effective solutions as clinical research and experience in the field of laser hair removal have increased. Due to variations in patient skin and hair biology characteristics, clinical protocols, and electro-optical parameter tuning, the effectiveness and safety of laser and light-based hair removal technology vary significantly among manufacturers.
