\n

What is the main purpose of your eyebrows?<\/h3>\n

Eyebrows primarily help protect your eyes by keeping out moisture, like rain or sweat, and deflecting debris. They also shield your eyes from the sun, making them key for clear vision. Humans rely more on their sight than any other sense, so brows serve an important protective function.<\/div>\n

\n

How long does it take for your eyebrows to grow back?<\/h3>\n

Your brows have an average lifespan of four months. Each eyebrow hair falls out and a new one grows back in this cycle, so if you overpluck, they should regrow in about four months. Hair can thin as you age due to hormonal changes, but this cycle stays the same.<\/div>\n

\n

Do eyebrows grow faster in any particular season?<\/h3>\n

Eyebrows tend to grow a bit faster during warmer weather. Factors like sunshine, increased activity and seasonal hormone changes contribute to this quicker growth. If you’re aiming for fuller brows, let them grow out during the summer months.<\/div>\n

\n

Why do you raise your eyebrows when you speak?<\/h3>\n

Your brows move automatically in response to changes in your voice pitch. As your tone rises, your brows often go up too, acting as a form of non-verbal communication. This movement is usually involuntary and can show your emotions even if you don’t intend to.<\/div>\n

\n

Has eyebrow grooming always been popular?<\/h3>\n

Yes, people have shaped and styled their brows for centuries. Every culture has had different eyebrow trends, from shaving them off completely in Renaissance Florence to the barely-there brows of Elizabethan England. Modern trends, like the defined ‘scouse brow’, continue this long history.<\/div>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"

Aside from being the most therapeutic part of our makeup routine, brows do have a real function. Us humans rely on our sight more than any other sense, and brows work to protect our eyes, through keeping moisture out (like rain and sweat). They can also deflect debris, and shield our eyes from the sun: a new meaning to ‘power brow’, right? We may have evolved to lose most of our body hair, but eyelashes and eyebrows have remained in tact to keep our peepers clear.<\/p>\n","video_content":"","block_picture":32959},{"block_title":"They\u2019re an evolutionary advantage","block_content":"

While we’re not the only species sporting brows, we are the only mammals with eyebrows against bare skin. This is actually considered an evolutionary advantage, as other humans are able to interpret expression and emotion. While other mammals rely on brows as tactile sensors, we’re able to perceive anger, sadness and pure joy (like grabbing that freebie outside the tube station in the morn – rosemary water? Just what I wanted).<\/p>\n","video_content":"","block_picture":32960},{"block_title":"We\u2019re not the first ones to groom them","block_content":"

Yep, though the scouse brow may be the current zeitgeist, plucking, defining and even threading to keep brows in shape<\/a> are methods that go way back. Every culture throughout history has had a different way of shaping, we’re talking from 3500 BC. From shaving them clean off (looking at your Renaissance Florence), to barely-there brows with a tweezed hairline in Elizabethan England, brow trends are ever-changing.<\/p>\n","video_content":"","block_picture":32961},{"block_title":"The Mona Lisa doesn\u2019t have eyebrows","block_content":"

Never thought of that before, eh? Eyebrows are often considered the most important aspect of facial recognition (research suggests that it’s tricky to identify individuals in images when their brows have been removed), but obviously we know the famous face of the Mona Lisa pretty well. Interesting fact though, in 2007 a press release stated that that she was originally painted with lashes and eyebrows, but years of overcleaning may have faded them (Mona, one word: microblading<\/a>).<\/p>\n","video_content":"","block_picture":32962},{"block_title":"Your brows have a lifespan","block_content":"

It’s true. Your brows last four months on average, that’s how long it takes for the cycle to ‘refresh’ (each hair to fall out and a new one to grow back). Good news if you’ve overplucked (nineties babies can I get a ‘yessiree’), they should grow back. Of course, hair does thin as we age, thanks to changes in hormones, but the average lifespan is four months. As for plucking, if you’ve noticed a little bump appearing once you’ve pulled a hair out, that’s the follicle closing to try and save it. Cute.<\/p>\n","video_content":"","block_picture":32963},{"block_title":"Your brows are more active in the summer","block_content":"

That growth time speeds up come sunshine season. Yep, the warmer weather, a more active lifestyle, and the hormones released during this time, are factors contributing to faster growth. It’s only a minor change, but if you’re aiming for bushier brows, grow them out during warmer climes. Half-board to Portugal next week, anyone?<\/p>\n","video_content":"","block_picture":32964},{"block_title":"Brow-mouth coordination is a thing","block_content":"

Though brows can help us to identify and express emotion (pity brows to mum and dad, you know the drill), they’re also on a kind of autopilot, determined by pitch of voice. As your tone rises, so do your brows. It's like a non-verbal communication, that’s pretty much involuntary. In short: your brows could give you away (paint them on wisely).<\/p>\n\n
