The present disclosure relates to methods for inhibiting color fading in hair and for improving the color durability and stability of artificial color of hair. The methods entail forming a layer-by-layer (LbL) film on hair, and optionally forming a cationic surface layer on the LbL film. The LbL film is formed by applying a cationic polymer layer on the hair and subsequently applying an anionic polymer layer on the cationic polymer layer. Multiple cationic polymer layers and anionic polymer layers can sequentially be added as desired. Finally, the LbL film may comprise a cationic surface layer.

An isolated peptide for stimulating melanogenesis in a mammal subject is provided. The isolated peptide consisting of an amino acid sequence of FKCRRWQWRMK KLGAPSI (SEQ ID NO: 1). Also provided are methods and compositions for stimulating melanogenesis in a mammal subject.

The present invention relates to aqueous personal care, household care, and/or fabric care compositions comprising the instant copolymers. Also disclosed are methods for the rheological modification of aqueous personal care, household care, and/or fabric care compositions comprising the instant copolymers.

A method of combatting colour loss from a dyed material, the method comprising the steps of: (1) contacting the material with a composition comprising an electrophilic species selected from aldehydes, succinimidyl esters, and mixtures thereof; (2) contacting the material with a composition comprising a chelating agent and/or a salt of an amine and/or a carboxylic acid.

A method for the treatment of hair that includes the following steps: providing a pretreatment solution that includes a bis amino compound having a α-Hydroxy acid attached thereto; causing the pretreatment solution to react such that polymeric chains are formed; forming the polymeric chains into a biofilm; exposing the mixture to at least one hair; and wherein the biofilm defines a lattice structure.

A personal care conditioning and/or styling composition for a keratin substrate comprising: (A) at least one conditioning and/or styling ter/tetra polymer obtained by polymerizing: (i) about 50 wt. % to 97 wt. % of at least one cationic or pseudo-cationic monomer selected from the group consisting of diallyl dimethyl ammonium chloride (DADMAC), Hydroxyethyl-pyrrolidone-methacrylate (MO6), and/or Vinylpyrrolidone (VP); (ii) about 1 wt. % to 30 wt. % of at least one anionic monomer selected from the group consisting of (a) acrylic acid (AA), (b) acrylamido methylpropyl sulfonate (AMPS), and/or (c) sodium methyl allyl sulfonate (SMAS); and (iii) about 0.1 wt. % to 20 wt. % of at least one hydrophobic monomer selected from the group consisting of (a) polyoxyethylene (PEG)-18-behenylether-methacrylate (BEM) (b) Lauryl-ethoxylated-methacrylate (LEM), (c) stearyl acrylate (SA), (d) Streath-10-allyl-ether, and/or (e) Vinylcaprolactam (V-cap); and wherein said ter/tetra polymer has a cationic degree of substitution (Cat-DS) of greater than about 0.001 units, and wherein the cationic charge density is in the range of about 1 meq/g to about 6.5 meq/g; (B) at least one cosmetically acceptable excipient; and (C) optionally, at least one effective amount of personal care active ingredient. Also, disclosed is a process of preparing said ter/tetra polymer, and its method of use.

The present disclosure relates to an active ingredient composition for the care of human hair. More particularly, the present disclosure relates to a cosmetic composition for treating a keratinous material comprising a) at least one organic silicon compound and b) an aldehyde, the cosmetic composition being particularly suitable as a color protectant.

The present disclosure relates to an active ingredient composition for the care of human hair. More particularly, the present disclosure relates to a cosmetic composition for treating a keratinous material, wherein the cosmetic composition is a fluid and comprises at least one organic silicon compound and comprises at least one polyvalent metal cation, the cosmetic composition being particularly suitable for caring for damaged hair.

The disclosure relates to compositions for use before, during, and/or after the hair is subject to a process for altering the color thereof. The compositions comprise a combination of citric acid and at least one urea compound. The compositions provide strength and other benefits to treated hair. The disclosure also relates to methods of using the compositions as well as kits comprising the compositions.

The present invention describes a novel natural hair colour composition containing (a) a mixture of basic salt which aid in opening the hair cuticle and facilitating better penetration of dye which is natural plant-based extract; (b) a metal salt based mordanting agent which form a dye-metal complex. The invention further describes 2 step method of application which give better penetration and hence improved colour delivery and wash off resistance.
