FAQ

Why is U Shape 4D the most versatile pre-made lash fan size?

U Shape 4D sits between the subtle 3D and the full 5D lash fans — enough wispy volume to satisfy clients wanting more than classic lash extensions, but not so much that it overwhelms fine lashes or looks overdone for everyday lash wear. It's the pre-made fan size that works for the widest range of clients without adjustment.

Are U Shape 4D lash extensions suitable for fine natural lashes?

Yes — the 4-tip pre-made fan at 0.07mm is lightweight enough for most natural lashes. For very fine or sparse lashes, start with U Shape 3D lash extensions and step up once the client's natural lashes are stronger.

Can I mix U Shape 4D with other pre-made lash fan types?

Yes — use U Shape 4D as your volume lash base and add U Shape 5D lash extensions every 3–5 lashes for a graduated wispy effect, or mix with Spike Lashes for a textured hybrid lash finish.

How do I care for my clients' lash extensions after the set?

Avoid water and steam for the first 24 hours. Cleanse with oil-free lash shampoo every 2–3 days, brush gently with a spoolie, and schedule lash refills every 2–3 weeks.
