I’m 15 treatments in on my legs. I’ve seen a reduction to the hair growth speed but I will still need to treat beyond the suggested 16 times, and hope it eradicates the hair growth soon, because treating both legs takes a long time! I have used Nood on my face 12 times; I like that because it is working better than on my legs, and the face is so much quicker per session to treat than the legs.
