Benefits Of Trimming Eyelashes

  • Creates a natural look: Trimming your falsies to make the lash band match your eye shape and the lash line will make your extensions look more natural. You can also trim the lengths of your false eyelashes to shorten them to suit your desired look.
  • Avoids Irritation: If your fake lashes are too long, they can irritate your eyes. Trimming your extensions to fit the shape and length of your eyes can prevent your extensions from rubbing and irritating the skin surrounding your eye area.
  • Protects your eyes from debris: When your eyelashes are too long, the lash adhesive can gather dust and debris, irritating your eyes and causing styes. By trimming your false eyelashes, you can prevent dust from gathering on the ends of your eyelashes.

How To Trim Eyelashes Steps

Step 1: Prep your lashes

To help prepare your natural lashes, apply mascara and allow it to dry. This creates a stiffer shelf for your fake lashes to sit on.

It is also a good idea to curl your eyelashes too so that they will better match and blend in with the curve of your falsies.


We recommend L’Oreal Paris Voluminous Makeup Lash for voluptuous volume and intense length.

You can expect a full lash fringe that’s feathery soft, with no flaking, smudging, and clumping; Just voluptuous volume and intense length.

With this mascara, you can create your perfect eye makeup looks, get the long, full eyelashes you love, and choose this innovative volumizing formula and variety of brushes.

Step 2: Measure your lashes

Hold the set of lashes against your lash line and begin to position the fake eyelashes at the inner corner of your eye.

Lay the fake eyelashes against your natural lashes to measure the length of your lash line.

The end of the fake lashes should rest at the outer corner of your eye, so as you position the lash strip against your eye, move your finger to the point of the strip that extends past your eye. Hold your finger in that spot to mark where to trim.

Step 3: Mark the cutting point

Use tweezers to grab the point on your eyelash strip extending past your eye’s outer edge. Gently secure the lash strip between your tweezers, tightening the tweezers on the lashes to indent the spot that needs trimming.

Additional Tips On How To Trim Eyelashes

  • Before you start, rinse your pair of tweezers to remove debris, and get small scissors to cut the lashes. You need to get your tools cleaned and disinfected to facilitate trimming your fake lashes.
  • The first time you wear a new set of false lashes, you may need to trim the length of the band so that it doesn’t poke in at one or both corners.
  • When trimming your eyelashes, hold the lash up to your eye. It should fall just short of your natural eye length, so if it’s longer than that, snip some off.
  • Experts say you should make small cuts and re-check them against your eye between each snip until you meet your ideal lash length. You can’t add length back if you cut too much off.
  • Rather than measuring your lash strips against each other, measure and trim your fake lashes according to each eye. This ensures the lash strip fits your individual eye shapes, as your eyes may differ in size. Are you aware there are different sizes of lashes?
