The number of sessions really varies based on several factors - your hair type, the area being treated, your skin tone, and even your hormones. Most people need somewhere between 6-10 sessions for optimal results, spaced about 6-8 weeks apart. Coarser hair typically needs more sessions, and hormonal areas like the face might require additional touch-ups down the line. Areas like legs or underarms often respond faster than bikini or facial areas. It's also worth noting that you'll usually see significant reduction after just 3-4 sessions, even if you need more for maximum results.
