US Patent No. 11,931,433 B2 (Seyfi Alpaslan, Shirish Desale); Church & Dwight, Princeton, NJ, has patented a dry shampoo that cleans hair and provides a lasting color effect. The composition is comprised of  a coloring agent comprising: a starch material and a colorant blended and pulverized together to provide a uniform mixture; a color adhesion promoter that is effective as a film former and is present in an effective amount such that combing or brushing of the dry shampoo composition through the hair forms a coating of the coloring agent on the hair, improving adherence of the coloring agent to the hair after subsequent combings or brushings by improving resistance to removal of the coloring agent from the hair during the subsequent combings or brushings of the hair; a solvent; and optionally a propellant.
