On some parts of my body, I can tell my hair is growing much slower after about 5 weeks. I am following the directions, shaving, using no products, and passing Nood 3 times. I have very sensitive skin and did notice some skin discomfort. The light also flashed when I held my Nood upwards and gave me a horrible headache. Nood is not supposed to flash when it isn’t down on your skin, so I’m not sure what happened there. Aside from that, I will continue using (just much more carefully) and hopefully get the results advertised. Photo 1: 3 days after first treatment Photo 2: 2 days after 5th treatment
