I've been using this for about 2 months now and absolutely love it. My hair has never been so healthy, shiny and soft. I have very fine hair which easily gets dried out and/or weighed down and typically when I find something that works for me, it only works for a few days or a week and then it stops. As I said, I've been using this for about 2 months and my hair continues looking great. I use with the Neuma Moisture conditioner.
