Tried!

OH BTW,
you have to SHAKE and WAIT the bubbles/foam in the bottle change colour only APPLY.
If not , it doesnt work!

The problem with this is, you have to left it for a longer period to make sure the colour stays on.

So far so good.
My friend and I shares 1 bottle of the hair colour and we COULDNT finish it. It's TOO MUCH. WAY TOO MUCH.
My friend have long hair and I have short hair and we even help another friend of ours made highlights.
YET, we couldnt finish the whole bottle LOL.
