In only 3 treatments, I never got another ingrown hair on my legs again. I did not expect the hairs on my legs to disappear, only the ingrown hairs, and I couldn't have been more pleased with the results. Not only do I have beautiful skin on my legs today, but the hair growth has been reduced greatly. I still have hair on my legs, but much less than I had before.
I think if you go in thinking you're going to be hair-free at the end of your sessions, you will inevitably be disappointed. But if you expect the hair growth to be reduced, you will be very pleased with the results.
My next project is my bikini line, toes, and happy trail where I also get occasional ingrowns, and i'm really looking forward to it.
