Wash out hair dye questions / Halloween hair!

[SecretMermaid]

I would like to colour my hair black for Halloween - my hair is currently its natural colour, quite a dark brown. I've searched the forum a little and am considering using a semi permanent dye as it doesn't appear that would cause my hair any particular damage, however I really want it to be washed out by the following Monday (so dyed for the 31st of October and all washed out by Monday the 3rd of November). How best can I achieve this with minimal damage? Thank you :)

And is anyone else planning on doing anything else special with their hair for Halloween?!

Your best bet is probably a product like Roux Fanci-full, which should shampoo out easily. It can make hair feel coated, but it shouldn't be damaging or last too long on you. I'd guess it would keep your hair more manageable than those hairspray colors, too.

I don't recommend a veggie due like black Manic Panic or an herbal dye like indigo for this. Both are too permanent for what you want.

Yup, get one that says wash-in wash-out.
