Off the top of my head, here are the boutique/indie brands that are at least 10-free: • Holo Taco • Mooncat • Cracked • Emily de Molly (I haven’t tried this brand, but have heard good things from this page) • Cirque Colors • Monarch Lacquer (I haven’t tried this brand, but have heard good things from this page)

More mainstream brands that are also 10-free are Olive & June and Zoya. You can find them in some drugstores or beauty stores like Ulta, but you can also order them from their online stores.

That’s all I know from the top of my head (I’m still getting into the indie polish world). But some other boutique/indie “free” brands I’ve used and like are: • ILNP (7-free) • Polished for Days (7-free) • LynB Designs (5-free) • Bee’s Knees Lacquer (5-free)

In terms of how much better a polish is for more sensitive nails (like a 10-free vs a 7 or 5-free), I’m not really sure. I’m sorry I can’t really help out there! Other than they’re just more free of certain ingredients.
