I hadn't colored my hair in 6+ years, and after coloring it a dark violet color, I needed to get a color protecting shampoo. I went back to Wella and they have not disappointed. It lathers amazingly, it cleans my hair really well, and it doesn't leave my naturally very oily hair greasy looking. It also doesn't irritate the psoriasis on my scalp. The price is easy to work with as well!
