Laser Treatment in Hirsutism: An Update

In 2020, a study titled "Laser Treatment in Hirsutism: An Update" investigated the effectiveness of laser treatment for hirsutism, a condition causing excessive hair growth in women. The study found that long-pulsed alexandrite lasers and diode lasers were effective in reducing hair growth, with a single treatment reducing hair by 10%-40% and repeated treatments reducing hair by up to 90%. However, the effectiveness varied based on individual skin type, hair color, and treatment area. The study also found that higher settings of 60 J/cm2 and 50 milliseconds and 80 J/cm2 and 50 milliseconds significantly reduced mean hair counts. Despite the promising results, the study concluded that more research was needed to optimize treatment parameters and to develop technology that provides permanent and complete hair removal for all skin and hair types.
