dpHUE Cool Brunette Shampoo Deep blue pigments in the dpHUE Cool Brunette Shampoo ($26) cancel out the red, orange, and yellow undertones that may develop in colour-treated hair over time (or with sun exposure). The foaming cream helps neutralise this brassiness in brunettes, adding in silk proteins and hibiscus extract to soften and brighten hair as it cleanses, too.
