FAQ

Why use 0.03mm instead of 0.05mm for mega volume?

0.03mm allows 10D–20D+ fans without adding perceptible weight to the natural lash. 0.05mm is better for 5D–10D. The finer the lash, the denser the fan you can safely create.

Is 0.03mm suitable for beginners?

No — hand-fanning 0.03mm requires advanced isolation and adhesive control. For faster mega volume, try our Cashmere Easy Fanning 0.03mm instead.

What's the difference between hand-fan and easy-fanning 0.03mm?

Hand-fan lashes give you full control over fan size and shape. Easy-fanning lashes open automatically with light pressure — faster but less customizable.

How long do mega volume sets last?

4–6 weeks with proper aftercare. Cleanse every 2–3 days with oil-free lash shampoo and schedule refills every 2–3 weeks.
