How To Use Crazy Color Slate Hair Dye

Crazy Color Slate Hair Dye is designed to be applied to shampooed and towel-dried hair. Make sure to wear gloves while you are applying your hair dye and cover your hair evenly for best results. Using a tint brush or comb can help with this. Once your hair is fully covered, allow the hair dye to process for 15-30 minutes before thoroughly rinsing your hair.

Make sure to read the instructions with your hair dye product before you begin and always perform a patch test. Want to know more about dyeing your hair at home? Visit Blue Banana Hair Dye Guides.

Crazy Color Slate Hair Dye on dark hair is unlikely to be visible. For best results apply Slate hair dye to pre-lightened blonde or platinum hair. If you do want to try out this grey hair dye on your natural hair colour then why not perform a strand test to check the results first?
