When five-free just isn't enough, that's where the seven-free polishes step up to the plate. Ethyl tosylamide, an ingredient banned in Europe, and xylene, a chemical that can cause all kinds of organ toxicity when used in large quantities, are given the heave-ho in seven-free polishes. But here's where it gets tricky: Most conventional polishes don't contain xylene anymore, whether they tout it or not.

A seven-free nail polish that promises to also be chip-free for seven days? We're interested. P.S. -- no base coat required.

With just enough sparkle to look uniform, but not enough glitter to make it near impossible to remove, this sparkly new shade from Deborah Lippmann is unicorn-like in every sense of the word.

Say good-bye to barely-there nudes with a wiggle of your earthy-colored fingertips. Dark browns and earth tones are back, starting with this warm, cocoa-colored polish.

These polishes are for natural nail lovers who truly want to commit to their cause. Eight-free polishes exclude all the previous ingredients mentioned, plus triphenyl phosphate, a possible endocrine disruptor that may be easily absorbed through the nail, according to one study.
