SHi® Smart Foundation™ Soak-Off Gel Base Coat

Great structure starts with the right foundation.

SHi® Smart Foundation™ is a professional soak-off gel base coat designed to create a reliable bonding layer between the properly prepared natural nail and the gel system applied above it.

Its flexible, self-leveling formula applies in a thin, controlled layer to support adhesion while creating a smooth foundation for gel polish, soft gel systems, structure gel, and compatible professional nail enhancements.
