well, i recently colored my hair and it went crazy. it looked dull, blah, and it was really staticky. since i switched to head and shoulders shampoo and tresemee Sleek conditioner my hair has been amazing. it has even made my hair naturally straight so i don' thave to straighten it or blow dry it. that part really impressed me. plus, if you get the cooling affect shampoo it makes your scalp feel really good
