Currently available in Violet and Orange/Red, Manic Panic Colorizing Shampoo (6.7 fl. oz. bottles) helps your dye to last longer and look brighter. On blonde hair, the shampoo will help you to achieve pastel shades and will create highlights on brown hair. Got natural red hair? Use the Orange/Red as a firey booster! Violet will help tone down hair that's gotten a bit too orangey. Shampoo works with both Manic Panic and Special Effects dyes!
