Is this even achievable? Mascara can only really work if you're going in costume. What else is there, that looks real?
I use mascara to make my facial hair more visible, since some of it is light to me. You could use some of your hair clippings (cut super fine) and spirit gum, but I've never tried that.
I'm not sure. There's videos on Youtube explaining how. If your own hair won't do, crepe hair might do the trick in a pinch.
