Q: Can you use BioBrew™ Fermented Strengthening Serum on a dry scalp, or does it have to be used only after
you've washed your hair?
A: BioBrew™ Fermented Strengthening Serum is designed for use on a wet scalp and wet hair. Spraying BioBrew on a dry scalp could disrupt your style. If you are ever wanting to apply to a dry scalp or hair, we suggest spraying it into your hands and then working it in.
