What is blue shampoo and how does it work?

Colored/bleached: it helps preserve a cool tint longer.
Natural: it can correct warm highlights or revive color.
Do sunlight or pollution affect copper highlights?
Yes, exposure to the sun, chlorinated water, sea salt or pollution can oxidize pigments and turn color yellow or orange. Blue Shampoo helps to correct and prevent these effects.
