Lily Miller There are many different sizes, colors, and shapes of eyebrows. Our faces become distinctive thanks to them. Why do we have brows, though?
Originally, the purpose of our brows was to shield our eyes from sweat and rain. As a species, humans rely on sight more than any other sense, and without eyebrows, water can get in and seriously impair vision. In addition to protecting our eyes from the sun and debris, eyebrows can also do so. Our eyebrows and eyelashes persisted as we gradually evolved to lose the majority of our body hair.

What’s the Purpose of Eyebrows?
According to experts, the two main functions of eyebrows are to communicate and to keep moisture out of our eyes.
They Protect Our Eyes from Moisture and Light
Physically, eyebrows are meant to keep our eyes healthy and clear. They keep our eyes from becoming wet from sweat and rain, preserving our vision.
Have you ever noticed how the hairs on your brows arch outward and toward the sides of your face? By doing so, you can help any moisture move from your eyes and onto the side of your head. Additionally, brows can shield your eyes from dust and light while reducing the amount of light that reaches them.
They Help Us Express Emotions and Recognize Each Other
The brows play a significant role in human communication and expression. They enable us to express our feelings. One raised eyebrow conveys interest or skepticism. You can express surprise with two raised eyebrows.
More generally, eyebrows are crucial for facial recognition in addition to appearance and emotion. In an earlier study from 2003, scientists asked a group of participants to name the faces of fifty famous people, including former U.S. president the actor Winona Ryder, and Richard Nixon. The photographs were altered by the scientists to remove either their eyebrows or their eyes. When they were blind, subjects could still recognize the famous faces 60% of the time.
However, only 46% of the time could the subjects recognize the faces without eyebrows. According to researchers, this suggests that eyebrows play an equal or even greater role in helping us recognize faces than eyes do.
What Role Does Genetics Play in Eyebrows?
Scientists have determined that your brows’ thickness, color, and shape are inherited characteristics.
In one major study, scientists found a strong relationship between inheritance of specific genes and eyebrow appearance.
One gene may determine eyebrow shape, five genes influence eyebrow hair color, and one gene determines whether or not you will develop a monobrow. Four different genes may affect eyebrow hair texture.
The appearance of your brows is greatly influenced by environmental factors, though. Years of waxing or plucking your brows can change their shape permanently. Hair growth and eyebrow shape can both be impacted by injuries to the skin near your eyebrows.
Both eyebrow abnormalities and eyebrow characteristics are inherited. Loss of eyebrows, or madarosis, is among the most prevalent abnormalities affecting the brows. Loss of eyelashes is another condition that is referred to as madarosis. There are numerous different inherited disorders that can cause this.
Eyebrows Form Part of Our Identity
Whether we have big bushy eyebrows, or styled “brows”, our eyebrows play a big part in making us look unique.
They also assist us in identifying well-known faces. We might not be able to identify our friends or family as easily if we didn’t have eyebrows.
We can determine a person’s gender by looking at their brows. Because women typically have thinner eyebrows higher above the eyes and men typically have thicker eyebrows closer to the eyes,
Additionally, the eyebrows of elderly people, such as our grandparents, may appear worn out or droopy. This is due to the fact that as people age, their brow muscles weaken and are pulled downward by gravity.
Express Yourself
As a communication tool, eyebrows can be used. You can make a variety of facial expressions with the aid of the muscles inside your face and the hair on the outside. The expression of anger or worry can be conveyed by a furrowed brow. You can convey surprise or even disapproval to someone by raising your eyebrows.
Mansperger summed it up best when he said that eyebrows have significant purposes. They assist us in communicating with those around us and in protecting our eyes.
Finally, brows can be amusing in their own right. Some people are gifted at raising only one eyebrow at a time or making their brows move in a certain way. Many people can actually teach their face muscles to move their eyebrows. While some people have natural talent, others need a lot of practice.

Last, Why Do We Have Eyebrows?
The reason why we have eyebrows was originally to keep rain and sweat out of our eyes. We, humans, rely on our sight more than any other sense, and with no eyebrows, water can get in and seriously blur vision. Eyebrows may also deflect debris and shield our eyes from the Sun.
