    how often should I use it?

    Our mask is designed to be a powerful treatment that repairs damaged hair. But the key to using it effectively is understanding how often to apply it and how much to use.

    Generally, you can use it once or twice a week, depending on how much repair your hair needs. If your hair is very damaged or over-processed, you might want to start using it more frequently, but if you’re maintaining healthy hair, once a week should be plenty.
