How do I remove hair dye stains from fabric?Updated 4 hours ago

TL;DR: For hair dye on fabric, pre-treat with Stain Remover, wait 10 minutes, then wash with Sensitive Laundry Liquid. Act fast — fresh stains lift more easily than dried ones. Hair dyes vary by brand and shade, so complete removal isn't guaranteed.

What do I need?

You need two products to treat hair dye on fabric: Stain Remover as a spray-on pre-treat that helps lift the dye from the fibres before washing, and Sensitive Laundry Liquid as the wash to follow up. Both are fragrance-free and Dermatest certified. The Stain Remover Starter Kit pairs Stain Remover with the Foaming Spray Bottle for targeted application.

Fragrance-free wash to follow the pre-treat. Dermatest certified for sensitive skin.

How do I remove hair dye step by step?

First, act fast if the dye is fresh. Blot any excess with a clean damp cloth — don't rub, which can drive the dye deeper into the fibres. Spray Stain Remover until the area is fully covered with foam and let it sit for 10 minutes. Wash according to the garment care label using Sensitive Laundry Liquid. Check the garment before drying — if any colour remains, repeat the spray and wash. Don't tumble dry or iron until the stain has gone, because heat will set it permanently.

✓ Step by step

1

Act fast if fresh. Blot excess with a clean, damp cloth. Avoid rubbing, which can drive the dye deeper into the fibres.

2

Spray Stain Remover until the area is fully covered with foam, then let it sit for 10 minutes.

3

Wash per the garment care label using Sensitive Laundry Liquid.

4

Check before drying. If the stain remains, repeat steps 2 and 3. Don't tumble dry or iron until the stain has gone — heat will set it permanently.

⚠ Before you start

Avoid Stain Remover on wool, silk, cashmere, alpaca, mohair, rayon, viscose, and linen. The enzymes can act on these fibres over repeated use. See the fabric compatibility article for the full list and what to use instead.

For unfamiliar fabrics, spot-test on an inside seam first. Colourfastness varies by dye and garment.

Spot-test first Not for delicate fibres

⚠ Set your expectations

Hair dyes differ by brand and shade and are often designed to be permanent on hair fibres. Some stains may only lighten rather than fully disappear. Treating as early as possible gives the best chance of removal.
