TLDR Laser hair removal has advanced to effectively reduce hair for various skin types and hair colors.
Since 1996, significant advancements in laser hair removal technology have been made, primarily utilizing melanin as a chromophore. Devices such as the ruby (694 nm), alexandrite (755 nm), and diode (810 nm) lasers, along with intense pulsed light, were effective for patients with light skin (phototypes I–III), achieving approximately 75% hair reduction. The long-pulsed Nd:YAG (1064 nm) laser was identified as the safest option for dark-skinned patients due to its longer wavelength, though other devices like the diode and alexandrite lasers, and intense pulsed light could also be used. For light hair, combination radiofrequency and optical devices, as well as photodynamic therapy, were under investigation.
