I adore this product. I've decided to let my hair gray naturally, and this shampoo gives the white/grey at my face a nice pop of shine! It rinses out fully without leaving that heavy feeling that some shampoos leave behind. Only downside is that you have to be careful about using and storing this product. If spill any shampoo and don't immediately clean it up, a purpley-blue stain might mark your shower curtain or shelf and it won't come out easily! This is not an everyday product - use once or twice a week for a great whiter than white pop of shine.
