At 1965 El Cajon Blvd near the University Heights border, Sandy Nails has operated in the 92104 ZIP code since 1998 and completed a full renovation in July 2024. Clients who book manicures before events frequently add same-day hair styling through Southside Salon SD on 30th St. The salon uses VOESH products that are PETA-approved and dermatologist-tested, covering gel manicures, dip powder, acrylics, nail art, and spa pedicures. Makeup and beauty prep for bridal parties or quinceañeras can be coordinated through Paris Beauty Studio on University Ave. The most technically involved services are full-set sculptured acrylic extensions with custom hand-painted nail art and encapsulated 3D design elements.
