Oxidation dyeing composition for keratin fibers comprising a cationic poly(vinyllactam) and at least one C10-C14 fatty acid, methods and devices for oxidation dyeing

摘要

A composition for the oxidation dyeing of keratin fibers, for example, human keratin fibers such as hair, comprising, in an appropriate dyeing medium, at least one oxidation dye, at least one fatty acid chosen from C₁₀-C₁₄ fatty acids and at least one cationic poly(vinyllactam) and dyeing methods and devices using the composition.
