Extensions sit on your natural lashes, so those natural lashes deserve some attention too. Good news: a growth serum and a full set can share the same lash line.

Can you use a lash growth serum with lash extensions?

Yes. Lash Population, a peptide-based eyelash growth serum, works on bare lashes or under extensions. You do not have to choose between a full set and healthy natural lashes.

Your extensions are attached to your own lashes, and those lashes keep cycling through growth and shedding no matter what is stuck to them. Supporting them is a long game, and it pairs well with regular fills.

How do you apply lash serum when you have extensions?

Apply a thin line along the upper lash line, once daily, on clean and dry lashes. Think of it like eyeliner, not mascara. You are treating the lash line, not painting the lashes themselves.

Use the serum daily for 1 to 12 weeks, then drop to 2 to 3 times per week to maintain. Keep the routine simple so you actually stick with it. A serum you forget about will not do much for you.

If you are newly booked in for a set, tell your lash artist what you use. They see your lashes up close every few weeks and can tell you what they notice over time.

What should you do between fills?

Keep your lashes clean, brush them gently, and skip anything that tugs. Our guide to caring for your lashes between extension appointments covers the daily basics, and these habits that protect extension retention are worth a read too.

Serum fits neatly into that routine. One quick swipe at night takes seconds.

Why bother supporting your natural lashes?

Because they are the foundation. Extensions can only be as comfortable and as good looking as the natural lashes underneath them. Stronger, fuller natural lashes give your artist more to work with, and they look better on the days between sets or when you take a break from extensions altogether.

Lash Population is NZD $79, recommended by lash artists, and backed by a 90-day Growth Guarantee. Salons can also order a wholesale 12-pack.
