Key Aftercare Rules (For Clients) Avoid Oil-Based Products: Alcohol and oil-based cleansers, makeup removers, and creams can break down the adhesive bond. No Mascara/Curler: Avoid waterproof makeup and mechanical curlers, which can ruin extensions and damage natural lashes. Hands-Off: Do not pull, pick, or rub your lashes. Brushing: Gently brush lashes with a clean spoolie daily to maintain shape.
