Quick answer
When you stop using an eyebrow serum, your brows gradually return to their pre-treatment appearance over a few months, as each hair sheds naturally and is replaced by one that grows back as it did before. To keep your fuller brows, keep using your serum: once you're happy with your results, our Eyebrow Enhancing Serum only needs 2 to 3 applications a week.
You've finally got the brows you've always wanted: fuller, thicker and beautifully defined, with the gaps filled in and no more drawing them on every morning. So what happens if you stop using your eyebrow serum? When you stop using an eyebrow serum, your brows gradually return to their pre-treatment appearance. It doesn't happen overnight: the brow hairs you have now stay until they shed naturally, and the new hairs that replace them grow back as they did before you started, so over the next few months your brows slowly look sparser again. To keep your fuller brows, keep using your serum. Once you're happy with your results, our Eyebrow Enhancing Serum only needs 2 to 3 applications a week to keep them looking full, thick and defined.
Here's exactly what happens when you stop, why it happens, and the easy way to keep the brows you love.
What happens when you stop using an eyebrow serum?
Every brow hair follows its own growth cycle: it grows, rests, falls out and is replaced by a new one. A good brow serum works with that cycle, helping each new hair grow in fuller and stronger. Our Eyebrow Enhancing Serum does this with clinically studied Myristoyl Pentapeptide-17, which supports brow hairs as they grow, alongside hyaluronic acid, phyto-collagen and pumpkin seed extract to hydrate and condition the brows and the skin beneath them.
When you stop, the brow hairs you already have don't suddenly change. They stay put until they naturally shed. It's the new hairs that grow in afterwards, without the serum's support, that come back the way your brows were before. Because every hair is at a different stage, the change is gradual and happens over a few months, not days.

What changes when you stop
Brows slowly lose their fullness
As your serum-supported hairs shed naturally, the new ones grow back as they did before. Most people notice the difference gradually, over a few months.
Patchy areas can return
The gaps your serum helped fill in, often at the tails or where you used to over-pluck, can slowly become noticeable again.
No sudden fall-out
You might spot the odd hair on your pillow, but that's normal everyday shedding, the same as always. Stopping doesn't make your brows fall out.
Back to filling them in
As your brows return to how they were, the brow pencil and powder may start creeping back into your morning routine. Keep going, and you keep your results.
Myth or fact?
Things people worry about
Myth"My brows will fall out if I stop."
Fact: No. Your brow hairs stay until they shed naturally, just as they always have. Stopping doesn't cause extra fall-out.
Myth"Once they've grown back, they're back for good."
Fact: Not quite. The new hairs that grow in after you stop come back as they did before, so keep using your serum 2 to 3 times a week.
Myth"I'll need to use it twice a day forever."
Fact: No. Twice a day for 8 weeks, then just 2 to 3 times a week to keep your brows looking full.
Love your brows?Keep using your serum.
Will my eyebrows go back to how they were before?
Yes. Over the next few months, your brows return to their pre-treatment appearance, just as they were before you started. That's why the secret to fuller brows is simple: keep using your serum. Once you love your brows, just 2 to 3 applications a week keeps them full, thick and defined. And if you have stopped, it's never too late: start again, apply morning and night, and many people see visibly fuller brows in 6 to 8 weeks.
How to keep your fuller brows
Switch to maintenance mode. Once you're happy with your brows, usually after around 8 weeks of twice-daily use, you don't need to apply your serum every day. Just 2 to 3 applications a week keeps them looking their best.
Put down the tweezers. Over-plucking is one of the most common reasons brows thin in the first place. Tidy stray hairs below the brow only, and let your natural shape stay full.
Be gentle. Scrubbing off brow make-up pulls at the hairs. Our dual-sided face cloths remove even waterproof make-up with just water.

Thinking of switching brow serums?
If you've stopped because your current serum didn't work for you, or you didn't like what was in it, here's what to look for:
- Hormone-free, with no prostaglandins. Some brow and lash serums use prostaglandin analogues, which have been linked to irritation, darkening of the skin and, in rare cases, permanent changes in eye colour. Our Eyebrow Enhancing Serum doesn't, and it's suitable for sensitive skin.
- Ingredients that work as a team. Clinically studied Myristoyl Pentapeptide-17, hyaluronic acid, phyto-collagen and pumpkin seed extract, alongside sphingolipids and arginine to help strengthen each hair.
- Proof from real customers. "Works brilliantly, my eyebrows were virtually non-existent. Now I need to occasionally pluck them, something I haven't done for years."
- A promise you can trust. If you use it every day for 60 days and don't see noticeable growth, we'll give you your money back.
Our Eyebrow Enhancing Serum is £24.99 for a 5ml bottle, with up to 60 days of twice-daily use. Want longer lashes too? Our Lash and Brow Growth Serum Set gives you both serums for £44.99.
The science, simplyHow Advanced Eyebrow Growth Serum works in your skin
Brows grow in cycles. Each brow hair goes through a growth phase, a short transition phase and a resting phase before it falls out and is replaced. Brow hairs have a short growth phase, which is why brows stay short and regrowth can feel slow.
How a brow serum helps. Our Eyebrow Enhancing Serum supports new brow hairs as they grow with clinically studied Myristoyl Pentapeptide-17, while hyaluronic acid, pumpkin seed extract and phyto-collagen hydrate, nourish and strengthen each hair.
Why results fade gradually when you stop. The brow hairs you already have stay until they shed naturally. Only the new hairs that grow in afterwards return to how they were, so the change happens slowly, over a few months.
