This shampoo & conditioner combo is great for my hair and scalp. Within the past few years my head started to itch, and I tried multiple shampoos to try to treat it. I started using this shampoo about a year ago, switching off with other shampoos every few days, but my hair still wasn't at it's best. So, when the shampoo ran out, I ordered directly from the company (do not order from Amazon! I purchased there the first time, and although I believe it was the same, I think it was old because it had a subtle smell that is not in the one I purchased from the company). I have been using only this shampoo & conditioner combo for nearly 2 months and my hair loves it. The itch is gone, my hair is soft and looks healthy. I will definitely purchase again once this set runs out, but it will be the larger size. The only slight issue I had was the shampoo seems to separate about halfway through, so the thinner ingredients spray out, and I don't feel the hair is as clean. My simple solution was to unscrew the top, and squeeze the bottle a few times to mix it up, **** the top back on, shake several times and it's perfect again. :)
