FAQ
What is the difference between flat and classic lash extensions?
Classic lash extensions have a round base for a natural, mascara-like look. Flat lash extensions (ellipse lash extensions) have an ellipse-shaped base that sits flush against the natural lash, creating a darker lash line and a larger adhesive contact area for flat lashes better retention.
Do flat lashes last longer than classic lashes?
Generally yes. Flat lashes better retention is one of their key advantages — the larger flat base creates more adhesive contact area, improving retention by 1–2 weeks. This makes flat lash extensions ideal for flat lashes for oily skin or clients with retention issues.
Are flat lashes heavier than classic lashes?
No. Flat lash extensions are actually lighter than classic lash extensions of the same diameter because the ellipse shape uses less material than a full round cross-section. This makes cashmere flat lashes a good option for clients who want a bolder look without added weight.
Can beginners use flat lashes?
Yes — flat lashes are beginner-friendly. Flat lash extensions are applied using the same technique as classic lash extensions. The main difference is ensuring the flat base is correctly oriented flush against the natural lash for maximum adhesive contact.
Can I mix flat and classic lashes in one set?
Yes. Use flat lash extensions at the base of the lash line for a darker lash line effect and classic lash extensions through the rest of the set for a natural finish.
