Why use blue shampoo?
Like we said, brass is a pain in the…neck. So, what does blue shampoo do? Blue-tinted shampoo tames brassy tones in brunette hair. If you have highlights, balayage, ombré, or lightened hair completely, blue shampoo can lengthen the life of your hue and keep it fresh between appointments. Plus, if you’re aiming for a deep, shiny brown look, or if you're someone who spends a lot of time in the sun, you also might want to give it a try!
