Count on Bain Ultra-Violet Purple Shampoo to tackle all your bottle-blonde woes. This shampoo, which also works on lightened, bleached or gray hair, instantly neutralizes brassy and yellow undertones so strands maintain cool tones, while also strengthening the hair fiber and leaving hair soft and shiny.
How to use:
Apply to wet hair. Leave on at least 2 minutes, or longer depending on desired degree of neutralization. Rinse thoroughly. In case of contact with eyes, rinse them immediately and thoroughly. Use up to 3 times per week.
