I have nothing but WONDERFUL things to say about this shampoo.. First off.. The SMELL! WOW It smells amazing!! The reason I started using it is because my husband told me it makes the scalp smell great even after sweating. It never causes my hair to look greasy or heavy. This shampoo is a bit pricey but the bottle is HUGE and can last at least one year! I have very long hair and can have a bottle last me a year and a half! More than worth it!
