Laser hair removal works best on individuals with light skin and dark hair, as the contrast makes it easier for the laser to target the hair follicles. However, advancements in technology have made laser hair removal accessible to a wider range of skin and hair types.

Laser hair removal can significantly reduce hair growth, but it's typically considered a long-term reduction rather than permanent removal. Some hair may eventually regrow, but it's often finer and lighter in color.

Multiple sessions are usually required for optimal results. The exact number varies depending on factors like the area being treated, hair color and thickness, and individual response to the treatment. Generally, 6-8 sessions spaced several weeks apart are recommended.
