There’s a lot more to eyelashes and eyebrows than you might think. You might think they’re only for flirting and making expressions.

Humans have been losing a lot of their body hair for many hundreds of thousands of years. We still have our senses in the area above our eyes. So, you might be wondering: Why do we have eyebrows?

Our eyes need to be protected from liquids like sweat and rain, so the first and most obvious purpose of eyebrows is to do just that. Additionally, eyebrows play a crucial social role in assisting us in communicating with others.

Below are other purposes of eyebrows:

Eyebrows 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 or 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 shield your eyes from dust and light while reducing the amount of light that reaches them.

Eyebrows Help Us Express Emotions and Recognize Each Other

The brows play a crucial role in human expression and communication. We can express our feelings through them. One raised eyebrow indicates interest or skepticism. Surprise can be expressed with two raised eyebrows.

The ability to recognize faces generally depends on eyebrows in addition to appearance and emotion. One earlier study from 2003 asked participants to recognize the faces of fifty famous people, including former U.S. president Actress Winona Ryder and Richard Nixon.

In order for them to either not have eyes or eyebrows, the scientists altered the photographs. When they were blind, subjects could still recognize famous faces 60% of the time.

However, when the faces were absent of eyebrows, participants could only correctly identify them 46% of the time. This, according to scientists, suggests that eyebrows may even be more crucial to face recognition than eyes, if not more so.

Eyebrows Help to Make Your Face Unique

Your face is unique because of your eyebrows, which are a distinguishing feature. In fact, advances in facial recognition technology have made brows more crucial.

When the lower half of the face is obscured by a mask or scarf, one new type of algorithm can recognize a face using only the eyes and brows. Thus, using your brows to unlock your phone or speed through airport security may be helpful.

Humans can identify one another thanks to their brows. A celebrity’s eyes or brows were removed from photographs of the person in one study by scientists. The study discovered that people had an easier time identifying the celebrities in the photos without their eyes than in the ones without their brows.

Eyebrows Serve An Aesthetic Purpose

Eyebrows might also be used for aesthetic purposes. Around the world and across cultures, many people alter or enhance the appearance of their eyebrows with a variety of aesthetic techniques, including:

  • Applying makeup to eyebrows – Eye makeup is available in every drugstore, department store, and cosmetic shop. It typically consists of brow gel, brow pencil, brow powder, and brow pomade. To fill in, enhance, and shape brows, these products are used.
  • Tinting eyebrows – To improve or alter the color of the eyebrows, some aestheticians, salons, and spas offer eyebrow tinting; at-home tinting kits are also available. With eyebrow micro-blading, you can give your brows the appearance of fullness or shape by using a tattoo technique.
  • Removing hair from eyebrows – To shape brows and remove unwanted brow hairs, a variety of techniques including plucking, waxing, and threading are used.

Similar to the hair on your head and your eyelashes, your brows can be used as a fashion accessory or a way to express yourself.

Genetics and Eyebrows

You might be wondering why there are so many variations in how eyebrows appear from person to person now that you know what they’re for.

Scientists have found that genetics help determines eyebrow characteristics such as eyebrow color, eyebrow thickness, and whether you have a “monobrow” or “unibrow” — when there is little or no hairless space between the brows.

The appearance of your brows is influenced by a variety of factors in addition to genetics. For instance, especially in women, aging may cause brows to become sparse or patchy. When this happens, especially in men, the brow hair may become longer and coarser. Eyebrow hairs can also become gray, just like your head hair.

Final Words: The Purpose of Eyebrows

The delicate, perfectly curved hairs that cover our eyes are thought to help keep our vision clear by directing excess moisture, like sweat and rain, away from the eyes. Moisture can more easily be drawn away from the area around the eyes because of the shape and direction of the eyebrow.

Additionally, the brows serve as a filter for dust and other particles that could get into the eyes, blocking out light. Experts contend that eyebrows are fundamental to human communication, amplifying emotions like surprise, happiness, and rage.


Why Were Eyebrows Invented?

Since the time of Ancient Egypt, when both men and women participated in cosmetic trends and wore makeup, eyebrows have been important. Thick, bold brows were the style of choice for the purpose of paying homage to the Egyptian god of protection and good health, Horus.
