More moisture; more protection. Primer is a weightless leave-in mist that brings together the smoothing and detangling benefits of cutting-edge actives with substantial protection from heat (up to 450°F), humidity, pollution and UV rays. Think of it as an invisible shield that locks in moisture and helps your other products work harder. Use Primer as a prep step—after cleansing with New Wash or between wash days—for strands that are silky, safeguarded and set for whatever style comes next. The semicolon represents a smooth transition between two connected thoughts; in your haircare routine, Primer marks where cleansing ends and styling begins.
