I started my tests at the beginning of January and started mid January. By about week 3-4, I'd guess, I saw a huge difference in the hair growth on my legs. I was only having to shave 2x a week vs every other day (every day in the summer). Week 5-7 I was only shaving 1x a week. After that, I just started spot shaving 1x a week where I could feel anything. At 8 weeks, I am SATISFIED as far as my legs go. Every few weeks, I'm still noticing a few random hairs so I have been doing my legs 1x a week still instead of 1x a month (still just spot shaving) but will switch to 1x a month maintenance once I stop seeing those random hairs come in. As far as my bikini and underarms go, I'm not AS satisfied but still pretty happy with the results. I think being a different type of skin/texture of hair/thickness of hair/etc., it might be taking longer? But I have noticed a significant decrease in the amount of hair I have in those areas and it is a lot thinner than it was before I started. I started these areas a few weeks after I started my legs as I 100% expected this treatment not to work so I didn't want to waste my time. So, I am on about 13 weeks of those areas As I said, I totally didn't expect this to work being that you always see things promising what seems impossible and they never work. I gave it a try even though I was 100% skeptical because of the guarantee and money back option- there was really no risk except to not try it. But NOOD WORKS!! Yes, my bikini and underarm areas are taking longer than expected but hey, it's still less hair. I essentially have no hair on my legs now which is HUGE for me as my before picture is only after about a day and a half. My hair on my legs would already be growing back by the time I was done getting dressed and ready out of the shower... totally not exaggerating there, either. So, even if my bikini area and my underarms don't stop growing hair, I am still 100% satisfied with the Nood treatment. I would never be able to afford laser hair removal and the price is a bargain for what it does! I have already referred friends and family to this product, too! Thank you SO much, Nood!
