Prepare to be a chameleon
"Used this on my face-framing/money pieces, everything else is a nice, lighter purple. Started out a gorgeous dark green. Washed once, became more of a blue-y green. Second wash, very blue. Now 4/5 washes in it is electric blue in most locations, with a few strands that are almost a seafoam-y color. It's not bad by any means, and I'm real happy that all the colors it's changed have stayed a nice contrast to the purple on the rest of my hair, but overall it just wasn't quite what I was expecting or looking for color wise. I'm not sure how long I could have really classified the color as teal, it pretty much just went from very green to very blue."
