Cutting lash strips is the single biggest skill gap in DIY lashes. Do it wrong, and you'll feel a poke at your inner corner all night. Do it right, and nobody can tell you're wearing lashes. The secret is knowing where to cut and how much to take off. Measure the strip against your eye, then trim only from the outer edge in small increments to preserve the natural taper.

THE ONLY LASH CUTTING GUIDE YOU'LL EVER NEED

1. Measure the strip. Hold the lash against your eye. It should start where your natural lashes begin and end at the outer edge of your eye. Add 2mm.
2. Cut from the outer corner. Most people cut the inner corner first — that's wrong. The inner corner is naturally shorter, so cutting it ruins the taper. Instead, trim the outer edge with small scissors.
3. Cut in tiny bits. Remove no more than 2-3mm at a time. Then test-fit.
4. Angle your scissors. Don't cut straight across. Angle slightly upward at the outer corner to keep the wing shape.
5. Finish with a curl. Curl your lashes and the strip together once to blend them.

THE 3 CUTTING MISTAKES THAT MAKE LASHES LOOK FAKE

• Cutting the inner corner: The inner corner is the shortest part of your natural lash line. If you cut there, the lash won't taper — it'll look blunt.
• Cutting too much too fast: You can always cut more later. Removing 5mm in one go means you'll have a lash that floats on your eye.
• Ignoring your eye shape: Round eyes need less length at the outer corner; almond eyes can handle a longer wing. No universal cut exists.

THE RIGHT TOOLS MAKE CUTTING EASIER

You don't need fancy equipment, but you do need sharp scissors. I use small grooming scissors with a pointed tip. Blunt scissors crush the fibers, which makes the cut edge visible. A clean cotton swab and a little eye-makeup remover are also handy for cleaning the band before you test-fit.

A magnifying mirror helps more than you'd think. When you're cutting 2mm off a lash strip, precision is everything.

WHICH LASH SHAPE IS EASIEST TO CUT FOR A NATURAL LOOK?

Lash Shape	Cutting Ease	Natural Result
Natural / flat	Easy	Very natural
Wispy	Medium	Natural if trimmed from the outer edge
Cat-eye	Hard	Can look unnatural unless carefully blended

FAQ

How short should I cut my lash strips?

Aim for the lash strip to be about 1-2mm shorter than your outer lash line when your eye is open. That prevents poking.

Can I cut the inner corner to make them more comfortable?

Yes, but only the very edge — no more than 1mm. Otherwise, the lash loses its natural taper.

What scissors should I use?

Small, sharp grooming scissors. Blunt scissors crush the fibers, which makes the cut edge visible.

WHAT TO LOOK FOR IN A LASH STRIP BEFORE YOU CUT IT

The best strips for cutting have a thin, flexible band and no pre-made hole in the center. If the band is stiff, the cut edge will poke your skin. Look for lashes with fibers that taper at both ends — they'll blend even after trimming. If you're planning to wear them for 12 hours, pick a style with a reinforced spine that won't bend in the middle.
