Best wash in wash out hair dye

[Virgo28]

DD has long blonde hair and needs to dye it black for fancy dress party. She wants something that is going to wash out straight away i. e. The next morning. Is there anything on the market that will wash out that quick? Thanks

I'm not sure a semi permanent will wash out that quickly or will dye blonde hair black without it being a permanent dye. Why don't you get a wig from eBay or a fancy dress shop instead. Good luck

party shop wig.

Dye will be a nightmare to wash out and will go khaki.

Definately a wig .
