I have been using this Paul Mitchell Tea Tree shampoo for years and I still love it. Every once in a while I switch to another brand just because they say that's a good thing to do to avoid residue build-up from constantly using the same shampoo, but I always switch back to Paul Mitchell. It is a very high quality product that smells great. It's especially refreshing in the morning when you're trying to wake up. I use a conditioner afterward, but even without that the shampoo itself leaves my hair smooth and less tangled than other brands. The only problem is if you get it in your eyes it takes a while to rinse it out. It doesn't really sting, but just feels like your eyes have a cool sensation that's a little strange. But a minute later you're fine. The other suggestion is to buy it in bulk from a hair care product salon rather than buying the more expensive little bottles that don't last very long.
