Ranked in these QuestionsQuestion Ranking
Pro The colors stick
Pro Vibrant colors that lasts a while, even when washed three times a week
Pro Color stays with correct care
Used to be available in TONS of colors. They are currently rebranding and have only like 5 colors which doesn't work for rainbow-heads like myself.
Pro Washes out nicely
The Electric Blue and Green Ivy/Envy wash out very nicely, you can go 3 months between touch-ups.
Pro Smells amazing
Pro Very vibrant color
I use their red shade and the color that comes out of the tube is very similar to what will come out in your hair.
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
Con Takes a lot of dye for anyone with thick hair
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.
