Disappointed!
First, the color isn’t dark grey it’s more of a brown/black shade. Secondly, it is not waterproof. The color is pretty for a brunette which I’m not any longer. I now have silver hair and wanted to define my brows a bit.  Will not purchase again, very disappointed with this product. Don’t want to give this a star but it won’t let me enter without one.  As far as drying up? I will have to play with it more, and will update my review.
