Coloured hair spray?

I'm thinking off changing my hair colour just to see how it will look. I don't want to dye it permanently or with a wash-out dye that will take time to wash out, so I'm thinking of using a coloured hair spray, but i don't know everything about them.

I've heard that they are perfect for dying hair for only a day or night, which is perfect for me, but is this true.

How does my hair return to its normal colour? Is it when I shampoo and even then does it all go?

I'd also like to know where I can buy a spray in England and how much it will cost approximately.

Will a blonde spray be strong enough to work over fairly dark brown hair, and will it look the same as if I used a wash-out dye of the same colour, or will it look more artificial and tacky?

Thanks a lot in advance XD

using a spray color with be a perfect way to see if you suit the color. Yes it does wash out in a day with shampoo.

if you use a blonde spray (preferably BBlonde) it will show up after like 10 min of setting in. But the only thing bad about it, is that it's sticky like hairspray.

(sry idk how much it would be in england)
