Methods and Compositions for Dag Mitigation
Technologies are described for methods and compounds for mitigating dag on hair. The method comprises applying a monofunctional compound comprising a hydrophobic tail and a reactive head to the hair and applying a difunctional compound to the hair. The difunctional compound has a first functional component and a second functional component. The application of the difunctional compound enables the first functional component to react with the reactive head of the monofunctional compound, the second functional component to form a matrix in situ with the hair, and the hydrophobic tail of the monofunctional compound to extend from the hair. The hydrophobic tail imparts its hydrophobicity to the hair to mitigate the dag.
