I just want to share my results from the shampoo and conditioner from this line. Well, I believed that I had clogged hair follicles. That is why I began using the shampoo and conditioner. Yes, my scalp developed sore pimples, and my hair was coming out way more than it should. I read an article online about the benefits of tea tree oil shampoos then decided to try the Paul Mitchell line. The results were great. In about a week of washing my hair everyday my scalp cleared up, and the amount of hair loss went back to the normal range . For this alone, I love Paul Mitchell tea tree oil shampoo and conditioner. It's wonderful, because my hair looks so good too. My fine, color treated hair is shiny, and manageable. By color treated, I mean my normally grey hair has been dyed a blonde in the golden range. A little bit of my gold stripped away, but not enough to bother me. It is just a lighter golden blonde shade that I love anyway. I was hoping the shampoo would provide enough clarifying for my scalp with out being too harsh on my hair. I am very pleased that it worked in that regard for me. I have a layered hairstyle, and this shampoo and conditioner helps to keep volume in my hair as well. My scalp is not oily, so I assumed product buildup on the scalp is what lead to my scalp problem. However, if my scalp and hair issues were something other than buildup on the scalp, Paul Mitchell tea tree shampoo and conditioner resolved whatever the problem was, and I am thankful to Paul Mitchell. After my problem was corrected with my hair and scalp, I only have to wash and condition my hair every three days. And, no additional color change in my blonde has occurred yet. I have been using the tea tree oil shampoo and conditioner for a little over two months now. Still very happy. I'd like to add that I am over due a visit to my hairdresser for my roots to be done. Due to bad weather, and some other circumstances that occurred. I am also very glad my hair and scalp will be in good shape when I see my hairdresser.
