FAQ

What makes 0.20mm flat lash extensions different from 0.15mm?

0.20mm flat lash extensions are thicker and heavier, delivering a bolder, more dramatic lash line than 0.15mm. They're best suited for clients with strong, healthy natural lashes who want maximum classic definition — for special occasions, events, or photoshoots. For everyday wear, 0.15mm flat lash extensions are the more versatile choice.

Is 0.20mm flat lash too heavy for natural lashes?

0.20mm flat lash extensions are best suited for clients with strong, healthy natural lashes. For fine or weak lashes, use 0.10mm Flat or 0.15mm Flat instead to avoid putting excess weight on fragile natural lashes.

Can I use 0.20mm flat lashes for volume sets?

No — 0.20mm flat lash extensions are designed for classic 1:1 application only. For volume lash sets, use Easy Fanning Lashes 0.07mm to create lightweight 2D–6D fans.

Do 0.20mm flat lashes apply the same way as round classic lashes?

Yes — same technique, same lash adhesive. The flat ellipse base provides more contact surface for a stronger bond and a darker root effect. No new skills required for lash artists already working with classic lashes.

Which curl gives the most dramatic effect with 0.20mm flat lashes?

DD curl at 0.20mm creates the most dramatic open-eye, bold lash look. D curl is slightly more wearable for everyday drama, while CC offers a strong lift that works well for clients with downward-pointing natural lashes.
