i have a big problem :D

well, i'm not alowed bleach my hair but i want it to be BRIGHT pink >=[ my friend suggested i should get wash in-wash out white spray/ tube. I'm using Directions Flamingo Pink btw :]] Would this work? If not is there any way I can achive this colour? kk thanks ;]]

you've got the same problem i do! There isn't really a way to get around it, unless you want a wig, the spray doesnt really work for vibrant colors, and it really looks like you have to much hairspray on your hair and feels reallly sticky. I know this is the worst news and probably not at all what you wanted to hear so Im soooo sorry and i feel your pain. If its any help i dyed mine purple without bleaching and it looked pretty cool, it did wash out pretty fast but i wasnt concernerned with longevity so i was all good.
I wish you the best of luck!

How about a compromise? Pink streaks? Pink bangs? Pink undercolour?

I'd also suggest pink tips - very easy to get rid of.
