Keeping Up with Katie

Katie Holmes shares her hair care secrets.

Katie Holmes for Alterna

Cult hair care line Alterna Haircare is clinically tested, paraben-, sulfate-, and phthalate-free—and Katie Holmes-approved. In 2013, the actress proved her dedication by becoming a spokesperson for the brand, citing Alterna’s good-for-you ingredients as her draw. “Just like you want to put good food in your body, you want to put good products on your hair,” she says. Among her favorites from the line are the classic Kendi oil, Bamboo Style Dry Shampoo in Sugar Lemon, and the recently launched Replenishing Moisture Milk. “It’s incredible,” she said. “If you put that in after you shower and then you blow it out, the frizz is gone, it’s good for your hair, and you have a shine. It’s easy!”
