Selena Gomez has a dedicated legion of fans, who love her for many reasons—her openness, her authenticity. The April Vogue cover star also happens to be a social media master—famously, the most followed person on Instagram—and while she's taking a more measured approach to her selfie game these days, a quick scroll through her account reveals plenty of camera-ready beauty that's worth studying.

Fortunately, the hair and makeup rules according to Gomez happen to be delightfully simple: finding a signature look that merges girl-next-door with bombshell glamour and sticking to it, with a few minor adjustments here and there. For a red carpet appearance, it's a set of voluptuous waves, parted deeply to one side and blown out smooth with a perfect wing of black liner. That same delicate flick provides a pretty point of contrast with a low ponytail for a business meeting, while those voluminous lengths elevate the at-home charm of surreally lit skin. Even an easy updo maintains Gomez's trademark texture and, if extra ornamentation is ever required, a slick of red lipstick is a minor change that makes a major impact.

The secret to a perfectly mussed updo? Blow it out, then toss it up.
