        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.

        our story

        Our story began with a decade of complex research into the bioscience of hair, resulting in our patented molecular repair peptide. Through this research and the application of synthetic biology, we are able to do more with less, simplifying formulations and routines to support hair health and expression at home and in the salon.
