How often should you use a Kérastase mask?

Are you using your Kérastase mask correctly? In short: use a hair mask about one to three times a week, depending on your hair type, the type of mask and what your hair needs. How often you apply it depends on factors such as whether your hair is dry, oily, damaged or fine, how intensive the mask is (repairing or more maintenance-oriented), and what results you want to achieve, for example extra repair, shine or softness. Below you will find useful guidelines for each hair type and tips on how to get the most out of your Kérastase mask.
