How do I remove hair dye stains from fabric?Updated 5 hours ago

TL;DR: For hair dye on fabric, pre-treat with Stain Remover then launder with Sensitive Laundry Liquid. Spray the stain, wait 10 minutes, then wash. Hair dyes vary and are complex, so complete removal isn't guaranteed.

How do I remove hair dye step by step?

✓ 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 to fully cover the mark and 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 on: wool, silk, cashmere, alpaca, and other protein fibres.

Spot-test first on: rayon, viscose, and any delicate fabric. Colourfastness varies by dye and garment, so test on an inside seam before treating visible areas.

Spot test first Not for wool or silk

⚠ Set your expectations

Hair dyes differ by brand and shade and can be permanent. Some stains may only lighten rather than fully disappear. Treating as early as possible gives the best chance of removal.

Act fast Results vary No heat until gone
