After a disappointing trip to a spa with her kids, Sundae Spa's founder didn't despair. Instead, she was struck by inspiration. After years of teaching science, she knew how well kids engaged with interactive activities, learning more when having fun. She decided to start her own kid-friendly spa, building her business around the idea of the classroom experiment. Not only can kids come to Sundae Spa for a haircut or manicure, they can also mix their very own lotions and soaps that will keep them cleaner than a playground-administered cootie shot, learning about the science of hygiene as they do. The product range supports the ability to make vegan, organic, and paraben-free products, so every child can participate.

The spa itself looks like a candy shop of yore; everything is the color of bubblegum or frosting, right down to the floor tiles and manicure chairs. Many of the products sport a dessert scent, such as chocolate cake or cookies, and kids receive complimentary ice cream with each service.
