This class breaks down the fundamentals of hair color—covering semi, demi, and permanent color, as well as lighteners, developers, pH, and more. While the focus will be on Wella and how its lines differ (and when to use them), the core principles you’ll learn apply to any color line. Gain clarity on the science and strategy behind color so you can make confident choices and achieve consistent, beautiful results.
