Let me start by saying this: there is NO nail polish out there that is 100% non toxic or 100% safe for you. It truly is that simple, paint that will unnaturally stick to your nails and not chip is not something anyone has YET to make without any added harmful chemicals.
Why does that matter? You may think that because your nails are not your skin that nail polish is safe to use, think again! Mainstream nail polish does indeed enter your blood and contains extremely toxic chemicals that are linked to cancer, terrible skin reactions, reproductive damage and respiratory complications!
That being said, there are a few brands that are safer to use if you want that fresh mani pedi look. Here are some of my personal favorites (and yes, I always bring my own nail polish when I visit the nail salon once in a blue moon, and bring my own scrub, lotion, etc.). Hope this list is helpful!
