Con Never fade
I had their atomic pink on the ends of my hair and it tinted any color I put over it pink for six months after I dyed it and that was AFTER diluting it with conditioner.
Con Thick formula
The formula is so thick it’s difficult to apply. Also very difficult to get out of the bottle.
Con Fades quickly
Many of the colors start to fade noticeably after a week or so.
Con Color didn't take
The color washes out with the dye, leaving a splotchy discolored look. Works best with lighter colored hair.
Con Only lasted two washes

For just below shoulder length you’re looking at at least three boxes to cover all your hair if you have thick hair
Con Hard to get out of hair
It takes a few color removers to get the color out to a bleachable level.
