Query: So Disappointed

This product is not worth it!! #1. I dye my hair blue black and it stripped all the color out of my hair leaving it looking like I had light brown highlights. #2. It left a flakey residue on my hair and just made it look oily...maybe I over saturated, but there must be a very fine line between being enough and too much. There was also no way I was going to leave my house with this stuff in my hair for 48 hours. I had to wash it out the next morning. Total waste of money.
