We got a temporary hair dye from Wal-Mart. It was suppose to end up red and ended up hot pink. How do I get it out faster?

Using hot water will help it fade faster. Or try a mixture of shampoo and Woolite, in even ratios. Black hair dye usually always covers up mistakes like this too. I wouldn't use color oops/color fix, it can just make it worse. Same with trying to bleach it out.
