How to Apply Lashes Under Your Natural Lashes

Everything changes when you apply lashes underneath your natural lash line instead of on top. The lash looks like it's growing from your eye, not sitting on it. If you've ever said, 'They're so pretty but they're obviously fake,' this is the trick for you.

WHY UNDER-LASH APPLICATION IS A GAME-CHANGER

Under-lash application hides the band completely because it nestles into the natural lash root. It also keeps the lash in contact with your eye shape, so it moves when your lash moves. This reduces the 'doll up' look. It's especially brilliant for monolid, hooded, and deep-set eyes, where top-of-lash bands often fold and crease.

STEP-BY-STEP: HOW TO APPLY LASHES UNDER YOUR NATURAL LASHES

Prep: curl your natural lashes and apply one coat of waterproof mascara. Wait 30 seconds for it to stay.
Apply a thin line of lash adhesive to the false lash band. Use a latex-free glue if your skin is sensitive.
Wait 30-45 seconds until the glue turns tacky.
With a mirror at eye level, lift your upper eyelid slightly and place the lash under your natural lashes, as close to the roots as possible.
Press down for 30 seconds, then blink to seat it.
Blend by gently squeezing your natural lashes together with a clean mascara wand.

5 MISTAKES TO AVOID WHEN APPLYING UNDER YOUR LASHLINE

Using too much glue, which seeps into your waterline.
Not waiting for the glue to get tacky.
Placing the lash too far down on the waterline, causing irritation.
Skipping the mascara base coat, which makes the false lash stand out.
Pulling the lash away sharply; always soak with remover first.

UNDER-LASH APPLICATION QUESTIONS, ANSWERED

Can you apply strip lashes under your natural lashes with regular glue?

Yes, but use a soft, flexible band and a skin-safe adhesive. The under-lash placement can rub the waterline if the band is too stiff.

Do under-lash lashes stay on longer?

Usually. They move less with your eyelid motion. Expect 8-10 hours with a decent glue.

Is under-lash application bad for your natural lashes?

Not if you remove gently. Never pull or tug. Use an oil-based remover and soak for 20 seconds.

The under-lash technique only works if the strip is soft and thin enough to sit under your lash line without poking or lifting. That's why I recommend PHANSTA LASHES for this exact application. Their ultra-flex bands are designed to bend with your natural lash line, and the fibers are lightweight, so you get comfort and a flawless look.
