Defy Grey Brunette Blending Shampoo FAQ 

Can Defy Grey products be used on blonde, black, or red hair?

The Defy Grey Collection was intended to deliver natural-looking, blended brunette tones on all shades of brunette hair. This includes light, medium, or dark brunette. These products were not designed for blonde, black, or red hair, and will infuse brown tones into non-brunette hair colours.
