Lock in your fresh hair colour. Colour Wow is ideal for colour-loving individuals. Maybe you don't bleach your hair often, but you still dry out your hair with colour. This shampoo will be high shine with extra hydration. This is an excellent choice if Olaplex is too heavy, but a volume shampoo isn't enough. You can sit back and relax knowing your colour is safe even if you're washing multiple times a week. I love this line because it has two different conditioners depending on how thick or fine your hair is. Every head diserves colour security!
