Clear brow gel (previously mentioned here) holds the little hairs in place all day and makes my eyebrows look a little neater. Unless, of course, I rub them, for whatever reason. Then they look regular again.
If you’re new to brow grooming, I’d recommend a clear gel. Tweezerman’s Mousse used to be my favorite, but I haven’t seen it in any beauty stores in awhile. If you’re not new to brow grooming, can you recommend me a brand that doesn’t turn cloudy-looking after being open for a few weeks?
