Eyebrow shape is one of the most important parts to beauty. Your eyebrow shape depends on your facial features. It can help you look younger and "lift" the eye so it appears firmer.
For those of you, who prefer a wax or threading over a pair of tweezers, make sure you go to a trusted salon. I have seen a lot of eyebrow accidents. It seems like they always want to make eyebrows very thin and have harsh angles. Look through magazine and see how models and celebrities have their eyebrows shaped. Don't let them over do it. Thin eyebrows will age a woman faster then sun and birthdays!
Men do not need to "shape" their eyebrows. The only steps men need to take for perfect eyebrows is to trim them and make sure there are two!
