Jen Atkin

Jen Atkin is the maestro behind some of the most famous women in America’s hair, including Karlie Kloss, Gigi and Bella Hadid, and, of course, the Kardashians.

The celebrity hairstylist’s tribe of famous devotees also swear by her haircare line, Ouai, which she launched last year. Most recently, she added fragrances to the range, including a scent to match Ouai’s highly popular Rose Hair and Body Oil.

She also happens to be actual friends with all of her clients, as evidenced by her frequent appearances in Chrissy Teigen and just about any Kardashian's Snapchat.
