This shampoo and conditioner are very rich...if you're an oily haired girl you may not love this. While it is hydrating, and it does maintain your color...I find it's a little too heavy and rich for my hair which is baby fine hair(but not thin).. When I use this I have to wash my hair without fail EVERYDAY. even with a dry shampoo I still don't LOVE LOVE this. However, if I have a client with dry hair...or "aged" hair that gets colored, this works well. It's just a little too moisturizing for my hair. But it does a good job, smells good and lasts a long time.
I like all Redken products, I personally have used the color extend more than once and its a good shampoo, buts its not amazing! It's that shampoo I use if I'm out of what I'm currently using and I need to use something until I can go get something else. Overall its good! xoxo
