Frequently Asked
Everything you need to know before your first appointment with Sina.
Lash extensions typically last 3–4 weeks with proper care. Your natural lashes shed every 60–90 days and extensions shed with them — refills every 2–3 weeks keep them full.
Come with clean, makeup-free lashes — no mascara, oil-based products, or eye creams. Avoid caffeine, remove contacts, and wear comfy clothes since you'll be lying down.
Absolutely — when applied correctly with the right weight and length. Sina uses premium, lightweight extensions and safe adhesives, and proper aftercare keeps your natural lashes healthy.
Classic is one extension per lash for a mascara-like effect. Hybrid blends classic & volume for a textured look. Volume uses multiple ultra-fine extensions per lash for max drama.
Avoid water for the first 24 hours. After that, cleanse daily with a lash-safe, oil-free cleanser and brush gently with a spoolie. Avoid oil-based removers, steam, and sleeping face-down.
