The Pro: Jamal Hammadi
The Scene: Fresh and laid-back in the way only a California beach retreat can be, Hammadi's studio is frequented by James Franco, Shailene Woodley, and Linda Evangelista.
The Philosophy: "I approach beauty with a conscience." Backing this up is Hammadi's eponymous line of natural shea-butter-based haircare and grooming goods.
Tools of Choice: "I never go anywhere without a teasing brush, pins and hair ties, and FHI ionic irons. Topknots are having a moment. Play with bun placement! Change your part!"
