Few beauty boosts are as easy as a polish change. Ten minutes (or less) can transform your look from demure to daring, muted to mysterious. A quick color swipe can even lend a little star power.   Read on for the top nail trends of this very moment, including two unexpected hues and new faves of Beyoncé, Lauren Conrad, and more.       The freshest colors on the market right now are varying shades of minty green. Shown here is Essie’s “Navigate Her”. This color family makes for a mellow break from the recent neon and glitter boom. …But then, you can always return.                 Also hot is royal blue, an unexpectedly pretty primary spotted recently on Beyoncé. Try “Baker Street” by Nails, Inc., and earn bonus points for color blocking your new nails with a bright red or bold yellow ensemble.                 Remember ombré hair? One of the most quizzical tress trends in recent memory is fading fast (get it? fading?), but the tonal, dark-to-light effect is hotter than ever for nails. Modeled here by Lauren Conrad, it’s actually quite pretty, especially with a touch of sparkle.               Next up, polish strips have been around for years, but real progress has recently been made in the category. Sally Hansen’s no-brush-necessary Salon Effects product comes in countless prints and finishes. Leopard, of note, has become a crowd favorite.               Finally, favored by Lady Gaga and Rihanna, sharply pointed nails are a shape of-the-moment. Metallic embellishments are often added, giving the kittenish look an edge. Ladies, this final trend is not for the fainthearted.             Reporting contributed by Bailee Crowder, Art Institute.   (Photo credits, from top: Lead image via TheBeautyDepartment.com designed by Lauren Conrad, 1.
