My son has very sensitive skin and this doesn't make him break out at all.

Great coverage, easy wash out
Color: Purple
This covered my daughter’s medium brown hair SO WELL! And to my delight, washed out very easily at the end of the night. Would absolutely recommend!

Coverage and transfer. Still pretty good!
Color: Blue
I am cosplaying Sal from Sally face for Halloween and I tested it today. It worked great! Although, it does take a lot to do full coverage for your hair, its color is vibrant and looks pretty good. But, the one thing I don't really like is that there is a LOT of transfer. I put on my shirt after my hair dried and it still got color on the shirt. It isn't staining the shirt, and washes out great, and you couldn't really notice it from far away, but it's still pretty irritating.
