--> Teal Hair.
Hi there. I have all my colours to go teal, i'm using Directions turquoise cos SPX fishbowl was outta stock, & i have like 4 greens so i can test each one to see what one gives off the shade i want. I just wanted to ask, would i need to add much green to the turquoise to achieve teal?

I would recommend not adding any green to it unless your hair is WHITE blonde. Anything other than white will make it turn out a little more green anyway.
