Tentatively awesome
"My hair was a level 7 when I dyed it. I'd lightened it to a level 8, tried two other brands for similar colors before, both of which mostly washed out after two washes and both of which I found disappointing. I've been washing my hair in the mean time to strip as much of the color as I can, and using K18 to keep it as healthy as I can. So far, Nasty is incredibly promising. This is the most pigmented I've gotten it, with the least wash-out. Gonna give it a few days to wash my hair, and will update if it all washes out in one wash."
