Help me find a hair dye

[Hetyanni]

It needs to be blue, bright enough to work on dark blonde hair and make it as bright blue as possible but also needs to wash out after 2 or 3 washes.
Any recommendations? Thanks!

I'm not a hairdresser but when my hair was dyed blue at the ends (I'm light blonde), it had to be bleached first. It took months and months to fade and in the end had to be cut out. Could you try a 'party spray' type thing? I have no experience of them though.

It's for my 5 year old 🤣
Spray is a great idea

I have seen coloured waxes for hair. Or hair crayons?

Will take a look, she has so much hair - down to her bum - so chalks take forever!

Might be best with spray then

Was going to suggest Schwarzkopf Live but maybe not for a 5 year old! I'd go with the spray at that age.

Blue dye seems to be the one colour that never actually washes out.

Sod's law it is her favourite colour!
