Most of those cute little bottles lined up in your bathroom have a secret: they’re filled to the brim with chemicals. Some nail polish brands have nearly 30 chemicals all combined. These harsh chemicals can not only be bad for the environment, but also bad for you, as they cause nails to become brittle and have harsh fumes. No nail polish is completely natural, but the most important thing to look for are brands that are "3-free," meaning they don’t use toluene, dibutyl phthalate (DBP), or formaldehyde, which are all known carcinogens. Some brands also describe themselves as "5-free" when they don't use formaldehyde resin or camphor in addition.
Many of these brands still use other chemicals, so be sure to double-check the ingredients for others that cause you concern. Whether you already have the best of the best when it comes to natural cosmetics or you're just starting to green up your shelves, we’ve rounded up some of the best brands that have dedicated themselves to more natural nail care, so your next manicure can be headache- and toxin-free.
