I've been using nood regularly, according to the directions, for 3 months. Treatment areas have been my armpits and also my bikini area. I've not seen any change in the hair on either area. I also now have been having allergic reactions to my deodorant (which I've been using for years with no issues) and I have to shave my armpit more often because the hair growth agitates my skin. Using nood has made my skin more sensitive. Do not recommend
