With my light hair and fair skin, I had a little trouble finding an easy-to-use brow product that would fill in and fill out my rather thin, sort of sparse brows. I don't usually have the time and patience to use a pomade/wax and powder combo, and hadn't had too much luck with pencils either. My preference is for a mascara-like product like this one, but I've found that many of them are too dark or don't offer enough color. The "tame" side of this in ash is a perfect color for me and I love how the fibers help thicken and offer shape to my eyebrows. I haven't really used the "treat" side since I usually forget about it, but the price is great even if you only use one side. Maybe once I need to replace this one when the "tame" side runs out, I'll keep it by my bedside for treating.
