The disclosure relates to systems for altering the color of the hair, comprising a pretreatment composition comprising at least one cationic surfactant and a dyeing composition comprising at least one microtube-dye composite. The disclosure also relates to methods of altering the color of the hair using the systems, as well as kits comprising the systems.

Systems, methods, and kits for altering the color of the hair

The disclosure relates to compositions and methods for removing direct dyes from hair, the methods comprising contacting hair with a composition comprising (i) at least one organic salt selected from imidazolium-based compounds and/or ammonium-based compounds, and (ii) at least one surfactant. The compositions can further contain at least one co-surfactant and/or cyclic compound.

Methods and compositions for removing color from color-treated hair

Provided are methods of treating hair, the method comprising: contacting the hair with a mixture comprising: i. an ionic liquid comprising an imidazolium-based compound or ammonium-based compound, and ii. an anionic surfactant. In certain methods, the mixture further comprises a cationic direct dye.
