If you’re new to eyebrow filling, this is the guide for you. We’ll dive into how to pick the best products for sparse brows and have a look at how to fill in sparse brows for the most natural finish/
How to fill in sparse brows: Key takeaways
- Sparse brows can be caused by genetics, ageing, over-plucking, or hormonal changes — so if your brows have thinned out, chances are it's just science (not your fault, we promise).

- Precision lovers, meet your match: NYX's Micro Brow Pencil has a micro-tip built for sculpting sparse brows into something seriously polished.
- For a soft-focus, effortless finish, try brow pens like NYX's Fluff & Snatch! Brow Powder Pen, which melts seamlessly into brows for weightless, everyday volume.
- Chasing lift and long-lasting hold? NYX's Lift & Snatch! Brow Tint Pen delivers up to 16 hours of smudge-proof wear with natural-looking, hair-like lines.
- Small gaps need a different fix; brow gels like The Brow Glue Instant Brow Styler and Crazy Lift hold hairs in place for a fuller, laminated look that lasts all day.

Why do eyebrows become sparse?
If you find your eyebrows are thin or thinning, then there are plenty of natural reasons why it could’ve happened. A few common reasons why people’s eyebrows thin and become sparse include:
- Genetics - If your mum or dad’s eyebrows are thin, and yours are too, chances are it’s just genetics!
- Ageing - Hair can thin out all over the body as we age, including your eyebrow hair!
- Over-plucking - If you’ve been a religious eyebrow plucker for years and years, it could’ve damaged hair follicles and led to the thinness you’re experiencing now.
- Hormonal changes - changes in hormone levels, especially during periods like menopause, can impact hair growth all over the body, including eyebrows.

How to fill in sparse brows
Now you know what the best products for sparse eyebrows are; let’s look at how to actually use them!
Depending on the product you go for, there are plenty of ways to fill in gaps in your eyebrows. Here’s a quick rundown of how to use one of our brow pencils and glues to fill in larger eyebrow gaps:
- First, pick your brow product. For this tutorial, we’ll be using NYX’s Powder Louder Brow Pencil.
- Next, give your eyebrows a quick cleanse with NYX’s The Face Unglue Makeup Remover Cleansing Balm. Cleansing helps to remove any old makeup or debris that might’ve built up in your brows and might stop your pencil from adhering properly.
- After cleansing, make sure your brow pencil is nice and sharp, then you’re ready to go.
- Start by making short, tiny strokes at the front of the brow that go directly up, just like the natural hairs here.
- Keep drawing these mini hairs until you reach the arch, where hair direction changes a bit.
- At the arch, draw tiny sideways hairs to mimic how hairs grow at that point, filling out any gaps in the same way.
- Finish by setting your look with a coat of NYX’s Brow Glue Crazy Lift, which also adds volume and texture for a beautiful, natural finish.
