Hair dye on cream curtains

[MilestoneMum]

I rather stupidly brushed my head against our curtains whilst I had root touch up in my hair.

Is there anything I can do about the stain?

Oh dear.

Are they washable curtains? I would say vanish spray and then launder, but hair dye is pretty tenacious stuff.

I have a line of eyeliner on my bedroom curtains which refuses to budge.

Hopefully another poster will have an effective solution for you/
