I have what one might call, "unruly" brows, but up until recently have relied on my twice-monthly brow wax and trim to keep them in shape. Last time I was at Benefit, however, they sold me this awesome stuff called Speed Brow.
In about three minutes, you can define, tint and tame your brows with this fabulous stuff. It comes in three shades, including clear. It sells for $16.00 and can be purchased here.
