“I’m so thrilled to partner with such an iconic beauty brand,” says Alyson. “My hair goes through a lot on-set, but I’ve relied on Head & Shoulders for years to keep my hair and scalp healthy. Whether I’m picking up my daughter from a play group or I’m at a photo shoot, Head & Shoulders keeps my hair looking great so I can focus on more important things.”
