Eyebrows can make or break a look depending on how groomed they are and how neat or careless they look. Sometimes stray hairs sprout out from places where they're even more unwanted, like on the chin, between the brows, from inside the nose or on the upper lip. Tweezers are indispensable on a monthly, weekly or daily basis depending on how fast your hair grows and how thin or thick you grow and groom brows.
Even if wax or electrolysis are used for more permanent hair removal, errant hairs will spring up eternal and unexpectedly, so tweezers are must-have tools for the in-between pluckings. A second, helper tool for tweezers is an eyebrow brush -- and some people just repurpose a toothbrush. Used dry, wet, powdered with eye shadow, or dabbed in some hair gel, eyebrow brushes direct brows into the most flattering shape by following the direction of the brow bone.
Some manufacturers of tweezers charge more than others, but investing in a well-made pair saves a lot of time in the long run, as a fine-crafted pair will catch more little hairs and ultimately cause less pain. When tweezers get off-center or stop fitting together well, some companies even repair them for free.
