It Works, But [SEP] I dyed my hair soft black to cover the grey.  I thought it was the closest to my natural color.  I did not get the result I wanted.  I looked like I dipped my head in black paint.  I got ColorOops from the beauty supply store.  I followed the directions, including the 20 minute rinse.  My hair is now a mink brown.  It's beautiful, but I don't know how I would do my roots.  This is why I gave 4 stars, not 5.
