How do I get hair dye out of a white hat?

1Step OneBlot the stain with rubbing alcohol (isopropyl alcohol), using a clean, white cloth. 2Step TwoTreat natural fibers such as wool or cotton with a solvent such as lighter fluid, turpentine or mineral spirits; again, use a clean, white cloth. 3Step ThreeAlternatively, treat synthetic fibers with hydrogen peroxide, using a clean, white cloth. 4Step FourIf the stain persists, bring on the bleach. If a dilute solution of all-fabric bleach doesn’t work, soak the garment in a a solution chlorine bleach in water, following directions on the bleach bottle. Note that this step could ruin your clothes; test a small, hidden area for bleach tolerance. 5Step FiveOr, try a color remover, following directions on the box. Color remover will take out the fabric color as well as the stain, so you will have to re-dye your garment. Tips & Warnings A clean, white cloth ensures that your stain-removal efforts don’t pull any unwanted dyes out of the cloth and onto your garment; it also allows you to see how much of the stain you have pulled from the garment. Turpentine, lighter fluid and mineral spirits are flammable. Stay away from flame. Hope I helped<3

Put dawn dishsoap on either side of the fabric where the spot is, then put it in the washer and use bleach in the wash. It should come right out. I have a white cotton towel I’ve been using for years to wrap my hair after I color it, and it always comes out clean after bleaching it. I don’t even put detergent or dawn on it before I wash it. But do that for some added help.

It make take a few washes. Good luck!
