Celebrity hairstylist Sally Hershberger has coiffed just about every celeb you can name — including everyone from former First Lady Hilary Clinton to Tom Cruise, John Mayer, Julia Roberts and Lindsay Lohan. But that doesn’t mean there aren’t still a few stars left that she’d love to get her hands on. PEOPLE caught up with Hershberger at the grand opening of her new L.A. salon, where she dished about her dream clients, starting with Mad Men‘s retro-beauty January Jones. “She’s so gorgeous,” said Sally. “I love that whole Catherine Deneuve/Grace Kelly thing — but I want to do her in a modern-day vibe.” And another another famous blond she would style a little differently? “I love [Madonna‘s] long hair, but I felt like it kind of pulled her face down,” she says of the performer’s recent show in N.Y.C. “I don’t want to put her down because I love her. I would just love it a little smoother and a little more hot.” Hershberger, who also has her own line of hair products, Supreme Head, feels that the key to sexy hair is keeping things looking natural by using just a little bit of product. “You don’t want to see the product in the hair,” she says. “That’s the biggest mistake. You want to be able to run your hands through someone’s hair and have it just look sexy whatever way they move it.” — Jed Dreben
