Claims17
A method of removing copper and inhibiting copper deposition on hair and improving hair colorant uptake, comprising:
- applying to the hair a shampoo composition comprising:
- about 0.025% to about 0.05% of histidine, by weight of the shampoo composition;
- about 2% to about 50% of one or more detersive surfactants, by weight of the shampoo composition;
- about 20% to about 95% of an aqueous carrier, by weight of the shampoo composition;
- and
- a shampoo gel matrix comprising:
- about 0.5% to about 20% fatty alcohol, by weight of the shampoo gel matrix;
- about 0.1% to about 10% of one or more shampoo gel matrix surfactants, by weight of the shampoo gel matrix;
- and
- about 20% to about 95% of the aqueous carrier, by weight of the shampoo gel matrix,
- wherein the histidine penetrates inside the hair fiber form a copper-chelant complex;
- rinsing the shampoo composition and the copper-chelant from the hair, thereby removing copper and inhibiting copper deposition on the hair;
- and
- applying to the hair a conditioner composition comprising a conditioner gel matrix comprising:
- about 0.1% to about 20% of one or more high melting point fatty compounds, by weight of the conditioner gel matrix;
- about 0.1% to about 10% of a cationic surfactant system, by weight of the conditioner gel matrix;
- and
- about 20% to about 95% of a second aqueous carrier, by weight of the conditioner composition;
- and
- rinsing the conditioner composition from the hair.
