I have dark hair, so I wanted a natural-colored eyebrow mascara, and bought this. I bought 01, and it was a little lighter than I expected. However, it gives a natural finish, and I like the fact that it doesn't look like I'm wearing eyebrow mascara. I think it can be used on dark hair too. It keeps my hair in place and doesn't make it look frizzy, so I use it almost every day.
