FAQ

What are ellipse flat lash extensions?

Ellipse flat lash extensions are classic lash extensions with a flat, oval-shaped base instead of a round base. The flat ellipse base sits flush against the natural lash root, creating a darker, liner-like effect at the lash line and a stronger adhesive bond — all with the same 1:1 application technique as round classic lashes.

What is the difference between flat lashes and classic round lashes?

Flat lash extensions have a flat ellipse base that provides more contact surface with the natural lash, resulting in a stronger adhesive bond, a darker root effect, and a fuller-looking lash line — all at a lighter weight than round classic lashes of the same thickness. The application technique is identical.

Do flat lash extensions apply the same way as round classics?

Yes — same technique, same lash adhesive. The flat ellipse base provides more contact surface for a stronger bond. No new skills required, making flat lash extensions an easy upgrade for any lash artist already working with classic lashes.

Are flat lash extensions suitable for sensitive clients?

Yes — the flat ellipse base is lighter than a round lash of the same 0.15mm thickness, reducing pressure on natural lashes. This makes flat lash extensions a good choice for clients with fine or fragile natural lashes who want a fuller-looking result.

Can I mix flat lashes with volume fans for hybrid sets?

Absolutely — use 0.15mm flat lash extensions as the classic base layer in a hybrid set and add Easy Fanning 0.07mm volume fans for texture and fullness. The darker root effect from the flat base makes the hybrid set look even more defined.
