The following step-by-step for applying eyelash extensions was provided by NovaLash EyeLash Extensions.
Step 1. Apply under-eye stickers
When applying under eye stickers/gel patches, you should avoid placing the sticker too close to the eye. The sticker should be placed over the lower lashes, about 3-4 millimeters from the lower lash line. Check lids from below to ensure upper and lower lids form a seal with no gaps.
Step 2. Choose extensions
Always use at least three different lengths of extensions that range from 6 mm to 14 mm in length. It is best to use 8 mm lash extensions in the inner corners of the eye to avoid avoid an artificial clownlike look. It is also important to use 8 mm extensions all across the eye, between the longer extensions to create a thick lash line. Failure to mix in short extensions results in empty gaps that make the long extensions look similar to spider legs. For a dramatic look, opt for the thickest (0.25mm) curly extensions. Finer extensions create a more natural look.
Step 3. Pick-up
Spread lashes out on your vinyl pad designed for quick pick up of the extensions. Orient extension properly in the tweezers.The extension should be oriented at a 90° angle to the straight tweezer for quick, accurate application.
Step 4. Dip
While holding the extension from its tapered end, dip the extension into the adhesive; make sure there is ample adhesive at the base of the extension. Swipe off any excess prior to applying.
Step 5. Isolate and Swipe
Isolate the natural lash with the curved tweezers. While holding the extension from its tapered end, swipe the extension along the natural lash. Coat the natural lash with adhesive from base to tip with no gaps in the glue. Spread the adhesive until smooth.
Step 6. Set
After swiping the natural lash with enough adhesive to coat it, set the extension on the lash about 1/2–1 mm away from the eyelid. Release the extension onto the natural lash. The lash should be facing upwards and parallel to the other lashes without any beads of glue. Do not touch the extension after setting. Move on to another area or the opposite eye and repeatedly apply extensions until It becomes difficult to isolate more natural lashes.
Step 7. Separate
No two extensions or natural lashes should be stuck together. Use both sets of tweezers to separate any extensions from neighboring lashes and/or extensions. Grasp and separate in a horizontal manner; best done while the adhesive is dry, but not fully cured. Never pull in a vertical direction or place any tension on natural lashes. Repeat the application and separation steps until every natural lash is bonded.
Step 8. Dry
When all natural lashes have an extension securely bonded, it is time to dry the newly adorned lashes for three minutes. Mist with distilled water, dry again for three minutes and perform one final round of separation.
