This shampoo is great for people who have bleached hair or like me have an ombre. It really does make a difference in keeping your blonde hair blonde and knocks out brassy,yellow tones which happens if you have dark hair and decided to make it blonde. It smells really nice and the fragrance lasts in your hair for days. Which is nice if you wash your hair every second or third day. You really do not need a lot and the shampoo won't turn your hair purple.
