I Tried 5 Different Ways to Remove Blue Hair Dye 

I experiment with vitamin C, toothpaste, dish soap, color remover and hair bleach to remove blue hair dye.
Vitamin C: amzn.to/3PV4FUr
Crest 3D toothpaste: amzn.to/43v17eR
Dawn Platinum: amzn.to/3PUAsFf
Clairol BW2 Hair Bleach: amzn.to/3NSXObE
DO NOT USE A DEVELOPER OVER 20. Don't risk melting your hair, even 20 may be too high for really damaged hair.
