Base Coat XX Logo


Because a more beautiful set of nails starts with a cleaner, healthier base coat. That is the foundation of our business and also the inspiration behind the two X’s in our logo: 10 fingers and 10 toes — XX.

You avoid harmful chemicals in your food and skin care products, so why put them on your nails? If you think it’s “because you have to,” think again. All our spa and body products used at Base Coat Nail Salon™ are plant-based and free of the most toxic chemical ingredients (including petrochemicals, parabens, sulfates, camphor and formaldehyde) to help you #TreatYoSelf to a cleaner, safer beauty experience.  You won’t find nail-damaging acrylics, hard gels or skin-aging UV lights at Base Coat. Instead, you’ll find a thoughtfully curated collection of 105 long-wearing custom colors with options to complement every skin tone, Oxygenating Medical Grade Soft Gel, LED light to cure, and our custom formulated plant-based creams, scrubs and oils scented with only essential oils and made of the cleanest ingredients possible.  

While Base Coat Nail Salon is free of the most toxic ingredients you would normally find in other nail salons, we do not want to ever mislead our clients into believing that our nail polishes, polish removers and state required EPA certified hospital-grade disinfectant we use in our salons are chemical-free. The reality is, in order for our nail polishes to be properly removed with out damaging your nails, stick to your nails and adequately dry, tools and surfaces to be properly disinfected it needs to have certain chemical ingredients. Until we discover miracle products that are 100% chemical-free, we will continue to provide the cleanest, safest products possible without compromising beauty and function.

*Base Coat Nail Salon products are responsibly Made in the USA, Leaping Bunny certified, vegan, gluten and cruelty-free.




When Tran Wills was pregnant with her fourth child, she decided she wanted one last pedicure before going into the hospital. Upon waiting for a treatment at a neighborhood salon, her nose started bleeding and she became nauseous due to the smells and harsh chemicals. She immediately walked out and, in her gut, knew that it was time for a better option—a healthier salon environment that everyone (even pregnant women, nursing moms, and those with allergies) could enjoy and benefit from. Tran had owned many businesses, collaborated with artists, worked as the social media director for a large online retailer, planned events, and helped build the creative community in Denver. She had acquired a list of accolades and, more importantly, developed a keen sense for community-based marketing and brand building. After spending years researching non-toxic nail products, she realized it was time to harness all that she had learned—and in 2013, she founded Base Coat as the first non-toxic nail salon in Denver, and one of only a few in the United States.
