8 Weird Things You Never Knew About Your Eyebrows
Many of us spend a lot of time and effort maintaining our eyebrows, from waxing to plucking to threading to filling them in. Many of us indulge in a huge variety of eyebrow services. Most people, however, don’t know just why we have these arched patches of hair on our foreheads in the first place — what purpose do they really serve? What does the shape and composition of your brows actually say about you?
Well, wonder no more! Read on to find out 8 fun, odd facts about eyebrows. You’ll never look at yours the same way again!
1. They’re designed to help us see.
Other than making one look beautiful or handsome, the real function of our brows is to keep moisture out of our eyes when it’s raining or when we sweat. That arched shape helps divert liquid to the side of our faces, keeping those peepers clear.
2. There’s a lot of hair in there!
According to the Bosley hair transplant company, the average person has about 250 hairs per eyebrow. However, some reports show that never-plucked brows can have as many as 1100 total hairs.
3. Brows have a lifespan.
The average lifespan of an eyebrow is four months, meaning the time it takes for each hair to fall out and new growth to fill in.
5. Brows are voice-controlled … kind of.
Brows help us signal emotions, but they’re also on autopilot: As the pitch of your voice rises, so do your eyebrows and vice versa. Not only that but when you make an expression without thinking, like when you’re surprised, eyebrows move in a way that’s symmetrical to each other. Conversely, when you make what’s called an ‘intended’ expression, like suspicion and curiosity, your brows will furrow asymmetrically.
6. They give humans a special edge.
Many mammals have brows and use them to express emotions, but we’re the only species that has eyebrows against bare skin — which, apparently, provides us with an evolutionary advantage because our expressions are easier for our fellow men and women to see and interpret.
7. We’re not the first to beautify our brows.
When we pluck and define our brows, we are actually taking part in a long, long history of facial grooming. Every culture and time period has had a different way of shaping their brows: In Florence during the Renaissance, people shaved their eyebrows off completely, while the colonial elite in 18th-century America preferred to beef their brows up using grey mouse skin.
8. Your brows say more about you than you know.
According to the book Amazing Face Reading by Mac Fuller, J.D., the type of eyebrow you have defines who you are. Curved eyebrows indicate someone who is people-oriented and needs real-world examples to understand a problem, while straight eyebrows imply that someone is more direct, factual, and logical, thriving on technical details. Angled eyebrows, Fuller says, show someone who likes to be right and strives to be mentally in-control, no matter the situation.
