How to remove rainbow hair at home?

I bleached over my Pink hair and I was able to get it to a light enough color to do something else with it while not having to go dark if you really don't want to though you could try using a color stripper I've never used then on my bright color but I have used it on red before and it did work though keep in mind it damaged the hell out of it to the same effect as 40 vol bleach did otherwise you'll just have to get a deep cleansing shampoo and keep doing it everyday till you can fade it out more
