Review (2/5): Only use this on areas where the hair is sparse ...
Only use this on areas where the hair is sparse, but definitely still exists, so thinning brows, etc. If you try to use this to fill in "bald" spots on your eyebrow, it will just stain the skin for a day or until you wash your face. Due to this you also cannot use this to correct brows where one is higher than the other, longer than the other, unless there is hair on the exact spot you are trying to paint the dye onto. Used in conjunction with regular a regular brow pencil, this product is OK, but if I still need the pencil then it's not worth the time to me.
