This service gently removes your old BIAB by (by SASSI) using a professional soak off technique that preserves the health of your natural nails. After the BIAB is safely removed, nails are shaped, cuticles are cleaned and a nourishing treatment is applied. Following the soak off, we treat your hands to a hydrating massage using a vitamin-rich lotion, followed by a cuticle oil application to restore moisture and maintain healthy nail growth.
Perfect for clients looking to refresh their manicure while keeping their nails and hands healthy and beautiful.

Removal of External Work: If you’re coming in with product applied elsewhere, this service ensures a safe and gentle removal of gel, BIAB, or acrylic applied by another salon or technician. We’ll carefully soak off the existing product, assess your natural nails and prep them for a fresh new set or let them breathe-your choice. Please note: this service may take a little longer depending on the product and condition of your nails.
