Removing hair dye: pick your surface

Hair Dye is a dye stain, usually from a splash or drip during home colouring, usually in the bathroom. The chemistry stays the same wherever it lands — but the safe way to treat it changes completely with the surface, which is why each pairing below has its own guide.

Not water-soluble

Water alone will not touch this stain; it needs an absorbent, surfactant or solvent stage.

Heat sets it

Keep hot water, steam and dryers away until the hair dye is fully out — heat fixes it permanently.

Fresh vs dried-in

Permanent hair dye is the hardest stain in this guide: it works by oxidising INSIDE whatever it touches, which is exactly what it does to carpet and fabric. Caught within minutes, blotting and detergent limit the damage; once the colour has developed, home methods lighten at best. Semi-permanent dyes respond better than permanent ones.
