When I first saw this app, the first things I thought were; it can't do anything, and it is probably money. I was way wrong!!! This app is amazing! When I tried to trick my friends that I died my hair, they fell for it! One down fall though, you have to trace all over your hair to color it. There are lots of colors too. Some of them do not show up well though. ( multicolor ones). There are a lot of adds, they are not inappropriate, and all of them at the most 5 seconds! I hope my thoughts help.
