So in January I decide I was bored with the red color in my hair so I dyed it with Colorsilk Dark Brown. Well I got tired of the dark brown and wanted to lighten it back up so...I bought some Color Oops. This is how it came out It did lighten it up some but not too drastic. I'm glad it didn't turn out orange or some crazy color. I have another box so I might do it again to see if it gets any lighter. The only bad thing I can say is this stuff STINKS BAD. Like sulfur, for days that smell lingered. Otherwise I'm happy with the results.
