Eyebrow Tattoo

An eyebrow is an area of short hairs above each  that follows the shape of the lower margin of the of some. In eyebrows serve two main functions: first, through and second, prevention of sweat, water, and other debris from falling down into the eye socket. It is common for people to modify their eyebrows by means of hair removal and makeup.

A number of theories have been proposed to explain the function of the eyebrow in humans. One approach suggests its main function is to prevent moisture (mostly sweat and rain) from flowing into the eye. Another theory holds that clearly visible eyebrows provided safety from predators when early  groups started sleeping on the ground.

Recent research, however, suggests eyebrows in humans developed as a means of communication and that this is their primary function. Humans developed a smooth forehead with visible, hairy eyebrows capable of a wide range of movement. Such eyebrows can express a wide range of subtle emotions – including recognition and sympathy.
