When it comes to makeup, nothing finishes off your look quite like some well-groomed brows. We already know that blondes should go a shade or two darker  when shaping and filling in their brows, but what about brunettes? Generally speaking, brown-haired women look best using a product in a shade or two lighter than their hair color. This way, the brows won't look too heavy or unnatural, and the skin won't appear washed out by a too-intense pigment.
Depending on the lightness or darkness of your locks, look for brown shades in hues that complement the undertones in your hair, such as walnut, deep honey, sable, golden brown, chocolate, cocoa, mahogany, chestnut, ash brown, or bronzed brown. When in doubt, go for a taupe shade, which is considered the most universally flattering color. And for the subtlest-looking finish, apply your chosen brow product  using short, feathery, hairlike strokes.
