FAQ

What makes cashmere PBT different from standard PBT?

Cashmere PBT is processed to be softer and more flexible, giving a more natural look and feel against the skin — especially noticeable for clients with sensitive eyes or those who find standard extensions uncomfortable.

Why does the flat oval base improve retention?

The wider base creates more adhesive contact surface between the extension and the natural lash, resulting in a stronger bond with less glue needed — particularly beneficial for clients with oily skin or active lifestyles.

Do flat lashes apply the same way as round classics?

Yes — same technique, same adhesive. No new skills required. Simply ensure the flat base faces down toward the natural lash for maximum contact.

Should I choose 0.15mm or 0.20mm?

0.15mm for natural everyday wear and sensitive lashes. 0.20mm for clients wanting more definition and drama while still enjoying the cashmere softness.
