Review (2/5): Does not work as well as parting your hair for coloring.
When I was using this to color my hair I wondered why everyone didn’t use this to color their hair all of the time. It took 3 minutes and was incredibly neat - not a drop of color splashed anywhere. Then after washing out my color I realized it’s too good to be true, as I had a lot of missed spots. My roots are pretty grey and I color my hair brown. I also have crazy thick wavy hair, so maybe this would work better for people with finer hair. Oh well.
