How do I remove hair dye stains from fabric?Updated 6 hours ago

TL;DR: Blot the excess without rubbing, pre-treat with Stain Remover for 5 to 10 minutes, then wash with Sensitive Laundry Liquid. Act fast, because fresh dye lifts far more easily than dried dye, and keep the fabric out of the dryer and away from a hot iron until the mark has gone.

What do I need?

You need two products for hair dye on fabric: Stain Remover as the spray-on pre-treat that helps lift dye out of the fibres, and Sensitive Laundry Liquid as the wash that follows. Both are fragrance-free and Dermatest tested. The Stain Remover Starter Kit pairs Stain Remover with a Foaming Spray Bottle for targeted spray.

How do I remove hair dye step by step?

Blot the excess dye with a clean damp cloth rather than rubbing, which drives dye deeper into the fibres. Spray Stain Remover until the area is fully covered with foam and leave it 5 to 10 minutes. Wash with Sensitive Laundry Liquid following the garment care label, then check before drying and repeat if any colour remains.

✓ Step by step

1

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

2

Spray Stain Remover until the area is fully covered with foam, then leave it 5 to 10 minutes.

3

Wash following the garment care label, using Sensitive Laundry Liquid.

4

Check before drying. If colour remains, repeat steps 2 and 3. Keep the fabric out of the dryer and away from a hot iron until the mark has gone, because heat will set it permanently.

⚠ Before you start

Avoid Stain Remover on wool and other protein fibres such as silk, where the enzymes can act on the fibres themselves over repeated use. See the fabric compatibility article for what to use instead.

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

Spot-test first Not for protein fibres

✓ What to expect

Hair dyes differ by brand and by shade, and some marks will lighten rather than disappear completely. Treat as early as you can for the best result, and take valuable or sentimental items to a professional cleaner.
