So far, I’m loving my shampoo bar! I’ve only tried the one and not the second one I purchased just yet. The set I purchased with the conditioner works great. I’m very happy with them. My hair has lots of body and bounce. I don’t have flat limp hair after using like so many other shampoos and conditioners I’ve used in the past. I can’t review about improving hair growth yet since I’ve only been using for a short time. I’ll definitely be repurchasing. Oh, I also love not having plastiv bottles!
