Chances are Pretty good that the best hair on any given red carpet has passed through the hands of Jen Atkin. The celebrity hair guru recently styled the locks of cover girl and newlywed Mrs. Hailey Bieber and the resulting photos quickly took over Instagram. If this isn’t It Girl hair, we don’t know what is.

We rarely share do-turials, but this one’s a goody. As a bonus, we’re sharing this sleeker, cool-girl look also created by Arkin on model slash mama look-alike, Kaia Gerber for New York Fashion Week. The jaw dropping looks couldn’t be more different, but we absolutely love them both.

For these polished looks — breezy beach waves on Beiber and silky straight strands on Gerber — Jen used a variety of non-toxic products, including a dry shampoo foam that’s honestly the game-changer you never knew you needed. She also used an old-school, insider styling product that we’d never heard of — an all-natural Indonesian pomade, Tancho Stick— to keep flyaways in their place, and we’ll never live without it again.

Get to know Jen in this interview we did celebrating Vogue’s 125th birthday last year, then scroll down for two pro hair tutorials that are simple but so chic. We’ll be planning plenty of date nights and social outings just to show them off…
