Do Eyebrow Growth Serums Work? 3 Real 6-Week Journeys

Stylist's #1 Brow Serum 2027: 3 sceptics, 6 weeks

Stylist has named BBB London Brow Boost Growth Serum the #1 Brow Serum of 2027. But awards don't grow brows. People do, with daily use and a bit of patience.

So we asked three real customers to try it every day for six weeks, film their progress, and tell us exactly what they thought, doubts included. Abbie couldn't leave the house without her brows done. Tonia thought thinning brows were just part of getting older. Taboka had already tried castor oil.

Here's what happened.

Abbie's story

"I'd never leave the house without doing my brows first."

Does Brow Boost work on sparse brows?

Abbie, a content creator who always filled hers in, tracked 6 weeks of daily use. S

he noticed healthier-looking brows by week 3 and was reaching for her pencil less by week 5. By week 6, she went out with no brow products on at all. Individual results vary.

Her timeline:

Week 1: Same brows she’d been hiding, but excited to start.
Week 3: Healthier-looking, especially in sparse areas.
Week 5: Reaching for her pencil less, which she didn’t expect.
Week 6: “I can’t believe the difference from where I started.”

Why she tried Brow Boost: a friend’s tip, and the fact it's a formula made with clean, plant-based ingredients, designed to help brows look thicker, fuller and healthier.

Tonia's story

'Nobody warned me that eyebrows change as you get older.'

We talk about ageing skin constantly. Ageing brows? Almost never.

Tonia noticed hers thinning anyway, and quietly filed it under “that’s just my eyebrows now.”

Then she tested Brow Boost for six weeks. One step. Every morning. Bare brows, before anything else.

For the first few weeks, there wasn’t much to see. So she stopped asking “where’s my transformation?” and started asking “what’s different this week?”

Then it happened: tiny new hairs, coming through in places she hadn’t noticed them before.

By week 6, her brows looked healthier overall. Individual results vary.

“Thinning brows aren’t necessarily something you have to accept as you get older.”

Noticing the same thing? You’re not imagining it, and you’re not out of options. Give it twelve weeks and if Brow Boost isn’t for you, our results-or-your-money-back guarantee has you covered.

Taboka's story

'I found a brow serum that's actually worked on my sparse eyebrows.'

This is the "but I've always used this" decade.

Declining oestrogen thins brow hair the same way it thins hair on your scalp, so a pencil that matched you perfectly for fifteen years suddenly reads too dark or too orange, because the hair underneath has changed even though the product hasn't.

Layering on more to compensate only draws attention to the gaps.

The fix: a softer, cooler shade like our Kajal Lash Liner for a gentler line, our Brow Boost to work on density rather than camouflage, and a lighter formula like our Lash Lift Mascara that won't weigh down drier lashes. If it's been five years since your last consultation, book one.

The shape that suited you at thirty may not suit the face you have now.
