Everything about eyebrows: facts, care & the latest trends
Share
Eyebrows do far more than frame your face — they protect your eyes, shape your expressions and are one of the first things people use to recognise you. Here's how brows grow and change over time, how to keep them healthy, and the brow trends everyone's asking for right now.
Eyebrow facts: how your brows grow and change
Why do we have eyebrows?
The main job of your eyebrows is to protect your eyes — catching dirt, sweat and rain before they run down from your forehead, and shading your eyes from bright sunlight. So yes, brows genuinely help you see.
Eyebrows give you a distinctive appearance
Along with your eyes and nose, your eyebrows are a key feature people use to recognise your face — studies confirm it. They also help you express emotion and let your eyes "speak". Shape, thickness and colour all shape how you come across, giving your face character and making it more expressive.
Hundreds of hairs per brow
You might not notice at a glance, but each eyebrow holds hundreds of hairs — sometimes up to around 1,000.
You lose brow hairs every day
Just like the hair on your head, you shed brow hairs (and eyelashes) daily. It's part of the natural growth cycle and nothing to worry about.
Why brow hairs stay shorter than the hair on your head
All hair grows at a similar speed — about 0.25–0.3 mm per day — but the growth phase differs by hair type. Brow hairs grow for only a short phase, while the hair on your head grows for two to five years. That's why scalp hair gets so much longer. The exact cycle length varies from person to person and comes down to your genes.
The brow growth cycle
Brow hairs run through a cycle of roughly four months: a growth phase, then a resting phase, before the hair falls out to make room for a new one. Eyelashes have a slightly shorter growth phase of about three months.
Thinning eyebrows
Like scalp hair, brow hairs (and lashes) can thin over time. Common reasons include:
- Over-plucking
- Age and hormone fluctuations
- Genetic predisposition
- Medication
- Diet
- Stress
It helps to work out the cause. Over-plucking — removing too much, too often — can leave hairs growing back thin, sparse or not at all, so pluck with care. A daily brow-care routine can slow visible ageing. If you suspect a hormonal imbalance or medication, speak to your GP (chemotherapy is a well-known cause of brow hair loss — more on that in a separate article). Diet matters too: folic acid, minerals, sulphur and vitamins A, B3 and E all support healthy hair. And keeping stress in check is good for your brows and the rest of you.
Brows can grow back
The good news: brow hairs can regrow — as long as the follicles are still intact. Age, genetics and over-plucking can permanently damage follicles, and a follicle that has died won't come back. Follicles that are still alive can be reactivated with a good brow & lash growth serum. Learn how serums work in our brow & lash serum guides.
Brows grow faster in summer
Your brows — and all your hair — tend to grow a little faster in summer. Better weather and more activity boost circulation, so nutrients reach the follicles quicker. A genuine seasonal growth boost.
Brows can be curly, too
Many brow hairs are actually curly, just like the hair on your head — often on people with curly hair. It's hard to spot because the brow has such a small surface. Keep it in mind when plucking or waxing, and if you have a curl, work it into your shape rather than fighting it. A brow specialist can share handy tips for curly brows.
There's no single "perfect" brow shape
Every brow and every face is different, so there's no one perfect shape for everyone — but there are easy ways to find the shape that flatters you.
The latest eyebrow trends
Brow trends have swung from the thin, over-plucked arches of the '90s and 2000s to full, natural, well-groomed brows. Right now it's all about looking like your brows — just healthier, fuller and neatly brushed up. Here's what's trending, and how to get each look.
The look right now: full, fluffy, brushed-up brows
The defining brow of the moment is soft and feathery, with the hairs brushed upward for a full, freshly-groomed effect — natural density over a hard, drawn-on line. Recreate it at home with a brow gel: brush the hairs up and set them with a clear or tinted brow gel (the "soap brow" technique does the same with a little less hold). Fill only where needed with a soft eyebrow powder, and support real fullness over time with a growth serum. The goal is polished, not painted.
Brow lamination
Brow lamination is a semi-permanent salon treatment that relaxes the brow hairs and re-sets them upward into a uniform, lifted shape — the professional version of the brushed-up look, without daily styling. It makes sparse or unruly brows look fuller and neater and usually lasts about 4–6 weeks. It pairs beautifully with a tint or henna for colour. Because the process can dry the hairs, aftercare matters: nourish daily and support regrowth with a brow serum. Best performed by a trained brow artist.
Hybrid brows
Hybrid brows combine two techniques — a henna (or skin tint) and a hair dye — for the best of both: the dye colours the hairs while the henna stains the skin beneath for a soft, filled "shadow". The result is a fuller, mapped, yet natural brow that lasts longer than tint alone — ideal for light or sparse brows that want shape and definition for weeks. Discover Hybrid Brows.
Brow henna
Tinting with brow henna colours both the hairs and the skin under and around the brow, for that full, bold, mapped look. A good henna such as Marie-José eyebrow henna is easy to use at home and stays on the skin for up to around two weeks (longer on the hairs). Unlike many kits meant for professionals only, ours is beginner-friendly — no course required.
Eyebrow threading
Threading removes hair by rolling twisted cotton threads over it, lifting the hairs straight from the follicle — no wax needed. Long used across Arabic and Asian countries and now popular in the West, it's prized for precise, clean lines. You can do it at home, but it's best left to a beautician or a specialised brow bar.
A note on microblading & semi-permanent techniques
Semi-permanent options like microblading (fine, tattooed "hair strokes") are still around, but the mood has clearly shifted toward less permanent, more natural results — lamination, henna and hybrid brows — that you can adapt as trends, and your face, change over time.
Frequently asked questions about eyebrows
How long does it take for eyebrows to grow back?+
Brow hairs run through a cycle of roughly four months, so noticeable regrowth usually takes several weeks to a few months — if the follicles are still intact. A growth serum used daily can help reactivate living follicles.
What's the difference between henna, hybrid brows and lamination?+
Henna colours the hairs and stains the skin for a filled, mapped look. Hybrid brows add a hair dye on top of henna for colour on both hair and skin that lasts longer. Lamination doesn't colour at all — it relaxes and re-sets the hairs upward for a fuller, lifted shape, and is often combined with henna or tint.
Which eyebrow style is popular right now?+
Full, natural, brushed-up brows — soft and feathery with the hairs set upward, rather than thin or hard drawn-on shapes. Brow lamination gives this look in-salon; a clear or tinted brow gel (or the "soap brow" trick) recreates it at home.
Why are my eyebrows thinning?+
Common causes are over-plucking, ageing and hormones, genetics, medication, diet and stress. Identify the cause, pluck sparingly, eat for hair health, and consider a growth serum. If hormones or medication may be involved, check with your GP.
