This one mousse -which already sounds better than "foam"- does what it does Cool Girl, her famous texturizing spray, the one Kate Moss uses. It adds volume, thickness, density, and texture to hair, and it lasts. In Sam's words: "It's important to me that hair feels good to the touch—it should feel soft, not sticky or stiff. Weightless hair is the perfect foundation for long-lasting, voluminous styles. This mousse is non-aerosol, so it applies evenly."
Feelings? It is a pleasant, light foam that is very easy to apply by combing damp hair with your fingers. It doesn't make a mess, it doesn't create cardboard, it's not heavy, and it doesn't feel like you're wearing a finishing product.
