LOVE this shampoo. It is gentle while completely cleansing hair and scalp. I have sensitive skin and this does not irritate my scalp at all. My colorist recommended it and I've been using it for a few months now. I like it so much I purchased the 32 oz container. It smells very nice, gives loads of suds, rinses easily, never irritates and my color has lasted much longer than ever before. The container cap has a double click - if you don't close it (feeling the double click) you'll find some of the shampoo leaks out.
