I probably spend too much time thinking about the next shade for my hair.
But this mint thing is where I'm at right now. It's taken a while to get the shade just right. I think Bleach London has been the biggest let down on this journey. Don't get me wrong, I love their white toner and the conditioner that comes with it smells beautiful, but none of their hair colours last more than a couple of washes.
So now I'm settled on Turquoise by Directions, pretty heavily diluted (I'd say 1:10 dye to conditioner ratio - maybe slightly stronger?) on bleached white hair.
It's starting to go a bit green-y at the roots because I was lazy and didn't bother toning it to white after bleaching it.
