I am a very easy sell when it comes to a health fad so, when kale became the superfood du jour, I keenly ingested it in its many forms while hoping for a miracle. Sadly none came— until now. Nails Inc. has launched Nailkale: a nail care range formulated with, you got it, kale, and promising healthier, stronger nails.

I’m ridiculously fussy about my manicure, so the promise of vitamins that I haven’t even heard of before (A, C, E, F and… H?) and a campaign fronted by Alexa Chung isn’t enough on its own to convert me to a new range. But Nails Inc. has managed to combine an alphabet of nourishment with colors that apply with a consistency thick enough for one-coat coverage and precision and thin enough for a speedy, super-shiny finish.

Aside from a kale-heavy base coat, the range includes a kale-y green shade, Bruton Mews, a deep cherry red Victoria, the nude Montpelier Walk, and the dusky pink Mayfair Lane—plus, if the ingredients aren’t transforming your fingertips fast enough, there’s a pearly translucent illuminating polish that can fake it. After two weeks of wear my fingers are looking healthy and feel stronger than ever, and I haven’t had so much as a drop of green juice.
