I wouldnt do that Ive tried and well the dye stayed in my hair

for 2 months and well it was supposed to only stay for like 2

days... But you know what you could do is:

Buy a real blue wig at a WIG store or COSTUME store they

are like 20.00.. I mean if you are that commited to scare her

then I guess 20 bucks would be fine..

Anyways

Hoipe I helped

Good Luck/ Dont give her a heartattack

Any beauty store has have blue spray. You're gonna need a few cans probably. The popular brand at my store is Jerome Russell, but I'm not sure if this is available in the UK. Keep an eye out for it!!
