It really works well
I only used 1/4 of a capsule because I only have a few grey/white eyebrow hairs.  It covered the white hairs well.  I'm going to buy this in light brown because despite the fact that my brows are very dark brown, the dark brown tint made them look BLACK BLACK.  So I'm trying the lighter shade to see if it looks a little less BLACK.
