Flat Lash Extensions 0.10mm | Cashmere Split-Tip Ellipse Base

The lightest flat lash extension — a split-tip ellipse base that delivers a darker, more defined lash line than round 0.15mm classics at a fraction of the weight. Ideal for fine, weak, or sensitive natural lashes that need definition without stress.

Why You'll Love It

• Darker than round classics at lighter weight — the flat ellipse base creates more adhesive contact, so 0.10mm flat bonds stronger and looks darker than 0.15mm round at less weight
• Better retention for oily skin — more adhesive surface area means the bond is less likely to break down from oils or active lifestyles
• Split-tip finish — the natural split tip mimics real lash texture for a more natural, dimensional look
• Cashmere PBT fiber — ultra-soft, featherlight on natural lashes for all-day comfort

FAQ

How does 0.10mm flat compare to 0.15mm round classic?

The flat ellipse base creates more adhesive contact, so 0.10mm flat actually bonds stronger and looks darker than 0.15mm round — at lighter weight. Ideal for clients who want more impact without the bulk.

Why is the flat base better for oily skin clients?

More adhesive surface area means the bond is less likely to break down from oils, giving better lash retention for clients with oily skin or active lifestyles.

Can I use flat lash extensions in a hybrid set?

Yes — place flat lashes as accent lashes for definition and add Easy Fanning Lashes 0.07mm fans for texture and volume.

Which curl should I choose?

C curl for a natural lift, CC for a moderate open-eye effect, D curl for a more dramatic open-eye look. CC is the most popular choice for clients wanting a noticeable lift without going too dramatic.

Are flat lash extensions safe for clients with sensitive eyes?

Yes — the 0.10mm cashmere PBT fiber is ultra-lightweight and places minimal stress on natural lashes. The FDA & CE certified materials are safe for professional salon use. Always perform a patch test for clients with known sensitivities.
