How to Apply Lashes Under vs Over Your Natural Lashes
One of the most common lash questions I hear is: Should I put my strip lashes under or over my natural lashes? And the truth? There's no universal "right" method — but there is a best method for your eye shape, your natural lash curl, and the final look you're chasing.
If you've ever struggled with lashes that look obviously fake, lift at the corners, or feel like they're sliding around, the placement is probably the culprit. Let's break down both techniques so you can get it right the first time.
WHY PLACEMENT CHANGES EVERYTHING
Over-lash application is what most beginners learn: you lay the strip directly on top of your natural lashes, close to the skin. It's quick, but if your lash line is hooded or your natural lashes are quite straight, you'll often see a visible gap between your real lashes and the false strip.
Under-lash application is the secret weapon of makeup artists. You place the strip under your natural lashes, pressing the lash band into the underside of your lash line. The result? A perfectly seamless lash line — because your real lashes cover the band. It looks like you woke up with dramatically longer, thicker lashes.
HOW TO APPLY UNDER YOUR NATURAL LASHES
- Start with clean, curled natural lashes. If your lashes are straight, give them a good curl with a lash curler first.
- Apply a thin line of lash adhesive along the band of your falsies. Wait 30 seconds or so until it becomes tacky — this is the #1 mistake people make.
- Look down into a mirror placed at chin level, so you can see the underside of your lash line.
- Use your fingers or tweezers to gently hold the lash strip horizontally, then tuck the band underneath your natural lashes, pressing it upward against the skin.
- Blink a few times to let your natural lashes settle over the band. Press gently to secure.
HOW TO APPLY OVER YOUR NATURAL LASHES
- Curl your natural lashes and apply your usual mascara. This gives the false lash something to grip onto.
- Measure and trim the lash strip — it should not extend past your outer corner.
- Apply adhesive to the band, wait for it to be tacky, then place the strip on top of your lashes, as close to the skin as possible.
- Press down gently with your fingers, then use an eyelash curler over the whole thing to mesh the false lashes with your natural ones.
- Finish with a light coat of mascara along the base to blend.
LASH LINES THAT NEED EXTRA LOVE
If you have sparse lashes, under-lash application is your best friend because the fake lash fills in gaps from below. If you have super dark, thick lashes, over-lash can look harsh — try under for a softer finish.
QUICK COMPARISON: UNDER VS. OVER
| Under Lashes | Over Lashes |
|---|---|
| Invisible lash line | More visible band if not placed carefully |
| Best for hooded or deep-set eyes | Best for round, protruding eyes |
| More natural, "done but not overdone" look | Dramatic, wide-eyed effect |
| Lifts the look of the lashes | Can weigh down straight lashes |
LASH PLACEMENT FAQ
Can you apply under lash extensions as well as strips?
Yes! The same logic applies to under-lash extensions. They sit below your natural lashes and are often more comfortable and less detectable than traditional extensions.
Does under-lash application work with magnetic lashes?
It can, but the magnet might not hold as well under the lash line. Strip lashes with a flexible band are the safest bet for this technique.
Will under lashes damage my natural lashes?
No, if you remove them gently with a dedicated lash remover. The key is not to pull or tug.
