Thanks to the amount of access granted by social media, celebrity hairstylists now amass followings as big as their clientele. So unless you swore off Instagram and the Kardashians at the top of the New Year, chances are you’ve already seen Justine Marjan throughout your feed.

Besides working her hands through the manes of every Kardashian sister, the hair pro also boasts a client list that includes supermodels (Kendall Jenner, Ashley Graham), chart-topping singers (Nicole Scherzinger), and actresses (Ashley Tisdale). When she’s not prepping them for a red carpet, you can find her backstage throughout Fashion Week, crafting runway-ready styles for top designers.

And while she’s navigating a busy schedule, she’s constantly sharing impromptu tutorials on her Instagram stories. In short: She’s a walking hair-care dictionary, so we had to know exactly what products she swears by day in and day out. Ahead, she tells StyleCaster her favorite products of the moment and what makes them must-haves for her kit.
