A hair mask ensures that a protective layer is put on your hair. Besides being nourishing, a good hair mask also provides a nice shine. How often do you use a hair mask? We say once a week. If you use it more often, there's a chance your hair will get very greasy. A hair oil is slightly different from a hair mask: hair oil is used as a supplement to the daily care of the hair. Contrary to what people think, a hair oil doesn't make your hair greasy, but rather keeps (dry and damaged) hair in a good condition. In addition, a hair oil, unlike a hair mask, can provide thicker hair, help with a dry scalp and help against hair loss.
