The disclosure relates to compositions for altering the color of keratin fibers and methods of using the compositions. The compositions comprise (a) a bonding system comprising: (i) at least one first bonding agent chosen from citric acid and/or salts thereof, and (ii) at least one second bonding agent chosen from amino acids, amino sulfonic acids, salts thereof, or combinations thereof; (b) at least one fatty alcohol; (c) at least one fatty acid; (d) at least one alkyl polyglucoside; (e) at least one alkalizing agent; and (f) at least one solvent. The compositions can further comprise one or more oxidation dyes, couplers, oxidizing agents, or combinations thereof.

Compositions and methods for altering the color of hair

The disclosure relates to compositions for altering the color of keratin fibers and methods of using the compositions. The compositions comprise (a) a bonding system comprising (i) at least one first bonding agent chosen from lactic acid and/or salts thereof, and (ii) at least one second bonding agent chosen from amino acids and/or salts thereof; (b) at least one fatty alcohol; (c) at least one fatty acid; (d) at least one alkyl polyglucoside; (e) at least one alkalizing agent; and (f) at least one solvent. The compositions can further comprise one or more oxidation dyes, couplers, oxidizing agents, or combinations thereof.

The disclosure relates to systems for altering the color of the hair, comprising a pre-treatment composition comprising at least one amine-based compound 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 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.

Cosmetic compositions, systems and methods for conferring responsive durable shaping of keratinous fibers employ at least one shape memory polymer that includes a three-armed branched polyethylene glycol (PEG) based polymer that is functionalized with one or more metal-coordination active groups. The shape memory polymer forms a crosslinked network coating on a substrate, for example a substrate selected from keratinous substrates, for example, hair. Hair coated with the shape memory polymer and treated with an oxidizing agent can be shaped, locked into shape, and reprogrammed by modulation of pH. The coated hair retains durable shaping properties through at least one shampoo treatment. The cosmetic compositions, systems and methods provide durable and reprogrammable durable shaping of the keratinous substrate, for example for styling hair.

Compositions systems and methods for conferring durable shaping of keratinous fibers

Cosmetic compositions, systems and methods for conferring responsive durable shaping of keratinous fibers employ at least one shape memory polymer that includes a four-armed branched polyethylene glycol (PEG) based polymer that is functionalized with one or more metal-coordination active groups. The shape memory polymer forms a crosslinked network coating on a substrate, for example a substrate selected from keratinous substrates, for example, hair. Hair coated with the shape memory polymer and treated with an oxidizing agent can be shaped, locked into shape, and reprogrammed by modulation of pH. The coated hair retains durable shaping properties through at least one shampoo treatment. The cosmetic compositions, systems and methods provide durable and reprogrammable durable shaping of the keratinous substrate, for example for styling hair.
