Claims25
A method of altering the color of hair comprising:
- (a) applying to the hair a pre-treatment composition comprising at least one non-surface active amine-based compound and at least one solvent, and
- (b) applying to the hair a dyeing composition comprising at least one microtube-dye composite and at least one solvent,
- wherein, in the microtube-dye composite, the dye comprises at least one hair dyeing agent.
A system for altering the color of hair comprising:
- (a) a pre-treatment composition comprising at least one non-surface active amine-based compound and at least one solvent, and
- (b) a dyeing composition comprising at least one microtube-dye composite and at least one solvent,
- wherein, in the microtube-dye composite, the dye comprises at least one hair dyeing agent.
A kit for altering the color of hair comprising:
- (a) a first container containing a pre-treatment composition comprising at least one non-surface active amine-based compound and optionally at least one solvent, and
- (b) a second container containing a dyeing composition comprising at least one microtube-dye composite and optionally at least one solvent,
- wherein, in the microtube-dye composite, the dye comprises at least one hair dyeing agent.
