Humans have lost a significant portion of their body hair over many hundreds of thousands of years. Above our eyes is one place where we still have it. You might be wondering, then: Why do we have brows?
We’ll learn today how having well-groomed eyebrows can improve one’s appearance.
What’s the Purpose of Eyebrows?
According to experts, keeping moisture out of our eyes and communication are the two main functions of eyebrows.
They Protect Our Eyes from Moisture and Light
The purpose of eyebrows is to keep our eyes healthy and clear on a physical level. They keep our eyes from becoming wet from sweat and rain, preserving our vision.
Have you ever noticed how the hairs on your brows grow 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 keep dirt out of your eyes and reduce the amount of light that enters them.
They Help Us Express Emotions and Recognize Each Other
Human expression and communication heavily depend on the brows. We can express our feelings through them. A single raised eyebrow conveys interest or skepticism. You can express surprise with two raised eyebrows.
Eyebrows are more generally significant for facial recognition than just looks and emotions. A group of people were asked to recognize the faces of fifty famous people, including former U.S. president Winona Ryder and President Richard Nixon. The images were altered by the scientists to either lack eyebrows or eyes. When they were blind, subjects could still recognize the well-known faces 60% of the time.
However, only 46% of the time were the faces recognized by the subjects when the eyebrows were absent. This, according to scientists, suggests that eyebrows may even be more crucial to face recognition than eyes, if not more so.
What Role Does Genetics Play in Eyebrows?
Scientists have determined that your brows’ thickness, color, and shape are inherited characteristics.
In one major study in 2015, scientists found a strong relationship between inheritance of specific genes and eyebrow appearance.
One gene may determine eyebrow shape, four different genes may affect eyebrow hair texture, five different genes may influence eyebrow hair color, and one gene determines whether or not you will develop a monobrow.
But your eyebrows’ appearance is also greatly influenced by the environment. The shape of your eyebrows can be permanently changed by years of waxing or plucking. Your eyebrow shape and hair growth may also be impacted by injuries to the skin nearby.
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 definition of madarosis. There are numerous different inherited disorders that can cause this.
