Root touch-up and highlight pens can be found at almost any beauty supply store. Ulta and Sally Beauty carry a variety of colors. These pens can also be purchased at many other retailers that sell beauty products, such as Amazon.com and Target. Local beauty retailers often carry these pens.
Root touch-up pens are temporary hair color in a pen or marker form. They are cost effective because they extend the time between salon visits. The pen is easy to use, and it gives a very natural look. It dries quickly, and the application stays on until it is washed out.
