Traditional nail polish is one of the most toxic beauty products on the market. It is packed full of chemicals that are harmful to breathe and harmful for fingernails. Chemicals like formaldehyde (a known carcinogen), dibutyl phthalate (known to cause reproductive issues), toluene (known to cause dizziness), and many others. These chemicals are especially harmful to pregnant women and children, and quite frankly I wouldn’t want them on my fingernails either. The EPA actually classifies nail polish as hazardous waste! Thankfully there are a variety of nontoxic options available. I put together a list below of some of the best nontoxic nail polishes available.
