People ask us all the time - Can I use lash serum if I have extensions? Yes, you absolutely can! And if you're thinking about rocking extensions for more than 6 months, you'll definitely want to keep reading.
Look, lash extensions are gorgeous - nobody's arguing that. But here's what most people don't think about: while your extensions are out there looking fabulous, your real lashes underneath are basically doing heavy lifting 24/7. All that extra weight adds up, and without the right care, your natural lashes can really take a beating.
Why Using Lash Serum with Lash Extensions Is a Great Idea
Think about what's actually happening with your lashes. Extensions are attached directly to your natural lashes. If those natural lashes get weak or brittle, your extensions won't last as long. Simple as that.
Lash serums work by nourishing your natural hair follicles, which helps your lashes grow in stronger and thicker. Use it consistently, and it can actually extend your lash growth cycle by keeping lashes in their resting phase longer.
What does this mean for you?
1. Your natural lashes stay stronger, so they can handle the weight of extensions better.
2. Your extensions will last longer because healthier lashes don't shed as quickly.
3. You might even grow more lashes over time, which means a fuller base for your next set.
4. And when your natural lashes are in good shape, your extensions just look better overall.
Many lash technicians actually recommend taking a 4-6 week break from extensions every so often to let your lashes heal naturally. Using a serum while you're wearing extensions can reduce that recovery time. Some people even use serum during their break to speed things up.
What eyelash serum is safe for eyelash extensions?
The right serum won't interfere with your extensions at all. Here's what to look for:
- Oil-free formula - oil breaks down lash adhesive
- Contains vitamins and peptides for nourishment
- Gentle on sensitive eyes - no stinging or irritation
- Labeled as extension-safe or tested with extensions.
- Trichologist approved

How to Use Lash Serum with Lash Extensions (Step-by-Step)
Using serum is super easy. Just follow these simple steps:
- Don't apply serum right after your lash appointment. The adhesive needs about 4 hours to cure properly. Adding moisture too soon can mess with that process.
- Clean your lashes with an oil-free cleanser before applying. Make sure they're dry.
- When you apply the serum, use it like liquid eyeliner. Draw it along your lash line where your lashes grow. Don't brush it onto the actual extensions. The serum needs to reach the roots, not sit on top of your extensions.
- One dip of the applicator is usually enough for both eyes. Using too much can cause problems - it might drip onto your extensions and weaken the glue.
- Give it a minute to dry before you touch your eyes or put on makeup.
Pro tip: And make it a habit. Use it every day for the best results. A lot of people prefer applying at night, but morning works too if that fits your routine better.
One more thing - never use a mascara wand to apply serum when you have extensions. Stick with the thin applicator that comes with it.

FAQ
What should you not wear with eyelash extensions?
Oil-based products are the main thing to avoid. Makeup removers, cleansers, and moisturizers that contain oil.
What makes lash extensions fall out quickly?
Poor aftercare is usually the problem. Constantly touching, rubbing, or pulling on your lashes weakens the bond. Not cleaning them properly or using products with oil will make them fall out sooner. Sleeping on your face doesn't do you any favors either.
What are bad lash extension habits?
A few things will ruin your extensions fast. Wearing mascara on them is one. Skipping daily lash cleanses is another. Picking at your extensions or pulling on them damages both the extensions and your natural lashes. Some people try to curl their extensions with an eyelash curler - don't do that. And not relaxing during your lash appointments can make application harder and affect how long they last.
