When Spruce Natural Nail Salon opened last year on Vine Street, their mission was to provide “five-free” nail services, using nail polishes free of the five most common toxins found in most other polishes: formaldehyde, formaldehyde resin, camphor, DDT and toluene. All of their products, including their Columbus-made Spruce-brand lotions, scrubs and cuticle oils, are also vegan and cruelty-free. The eco nail options offered the good, clean fun promised in their slogan for both clients and nail technicians — the Occupational Safety and Health Administration guide warns that exposure to typical nail salon chemicals can cause a range of illnesses from cancer to birth defects — but while the salon’s initial stance was to not offer gel nail polishes, they soon realized customers have a love affair with long-wearing gel polish. So Spruce found a Sprucey solution: BioSeaweed Gel. BioSeaweed Gel is still a five-free product, but it magically ensures a long chip-free wear and won’t damage the natural nail like traditional gel polishes can. It’s a nail polish miracle.
