Functions

The main function of the eyebrows is to prevent moisture, mostly salty sweat and rain, from flowing into the eye, an organ critical to sight. The typical curved shape of the eyebrow (with a slant on the side) and the direction in which eyebrow hairs are pointed, make sure that moisture has a tendency to flow sideways around the eyes, along the side of the head and along the nose. The slightly protruding brow ridges of modern humans could also still play a supporting role in this process.[citation needed] Together with the eyebrows, the brow ridges also shade the eyes from sunlight.

Eyebrow modification

It is common for people to pluck their eyebrows to maintain a clean and fashionable appearance with the use of tweezers and waxing.[citation needed] Threading eyebrows has also become a popular method because it does not pull at the skin. All of these methods can be painful for some seconds or minutes due to the sensitivity of the area around the eye but often this pain decreases over time as the individual becomes used to the sensation.[citation needed]


Some people claim that after they've been plucking/waxing their eyebrows for a few months, they become totally immune to the pain.[attribution needed] However, if this is not the case, there are ways to reduce the pain, such as doing it after a warm shower or bath.[citation needed]


Some people also choose to pierce their eyebrow, which is one of the most socially acceptable piercings. There are risks associated with this piercing, like sweat/dirt/hair getting into the piercing and infecting it, so daily cleaning is necessary.

The effect of the tinting was attractive although I thought it was most effective on the eyebrows.
