I just got my hair foiled and the salon where I go used this on me and when I commented on the delicious smell they told me I should use it because it helps maintain color...I love it
I think this faded my red color faster than any other shampoo I have used....I like the conditioner, though.
I found it to be very ... slimy. Yuck. It was as if I couldn't rinse it out of my hair no matter how I tried. Didn't like the smell, either: too harsh, not nice like most other Aveda products. Didn't see any difference in color conserving, either. The Sap Moss shampoo is much better, smells nicer, goes farther, rinses out well, and leaves my hair feeling silky.
I bought this to keep my highlights bright but I don't think it really made much of a difference. And it wasn't really moisturizing enough for my dry hair. But I liked the smell. I might try Sap Moss next.
