How can I thicken my eyebrows?

If you need thicker brows immediately, use an eyeliner sealant and powdered eyeshadow - a taupe shade works for most people. Dip the brush very lightly in the sealant and then into the powder and apply in short hair-like strokes, moving upward and outward like your actual brow hair would look once it's groomed.

This method allows you to literally draw on (in feather-like strokes) a thicker brow, fill in where necessary and elongate as desired. Simply apply a clear mascara afterward in an upward and outward direction and voila - you have all day brows that are water resistant. Magic!
