Abstract
Keratin protein cosmetic compositions are provided that include at least one keratin protein derived from human hair and a base cosmetic solution. Methods of treatment are also provided.
Claims19
A method for reducing hair breakage comprising the steps of:
- administering a keratin protein cosmetic composition to a surface of the hair in need of treatment;
- and
- rinsing the hair to remove any excess keratin protein cosmetic composition thereby increasing hair thickness and hair volume to reduce hair breakage,
- wherein the keratin protein cosmetic composition comprises:
- at least one keratin protein derived from human hair;
- and
- a cosmetic base solution,
- wherein the keratin protein is not denatured and maintains natural keratin protein conformation, and
- wherein at least about 30% of the keratin protein exhibits a molecular weight of at least about 443 KDa.
6 more elements
A method of reducing hair frizziness comprising the steps of:
- administering a keratin protein cosmetic composition to a surface of the hair in need of treatment;
- and
- rinsing the hair to remove any excess keratin protein cosmetic composition thereby causing the hair to exhibit less frizz,
- wherein the keratin protein cosmetic composition comprises:
- at least one keratin protein derived from human hair;
- and
- a cosmetic base solution,
- wherein the keratin protein is not denatured and maintains natural keratin protein conformation, and
- wherein at least about 30% of the keratin protein exhibits a molecular weight of at least about 443 KDa.
6 more elements
A method of reducing or mending hair split ends comprising the steps of:
- administering a keratin protein cosmetic composition to a surface of the hair in need of treatment;
- and
- rinsing the hair to remove any excess keratin protein cosmetic composition thereby resulting in split end mending or reducing the number of split ends
- wherein the keratin protein cosmetic composition comprises:
- at least one keratin protein derived from human hair;
- and
- a cosmetic base solution,
- wherein the keratin protein is not denatured and maintains natural keratin protein conformation, and
- wherein at least about 30% of the keratin protein exhibits a molecular weight of at least about 443 KDa.
6 more elements
A method of hardening and strengthening the nails of a mammal comprising the step of
- applying a keratin protein cosmetic composition topically to contact and coat all exposed surfaces of the nails in need of treatment to increase the hardness and strength of the nails,
- wherein the keratin protein cosmetic composition comprises:
- at least one keratin protein derived from human hair;
- and
- a cosmetic base solution,
- wherein the keratin protein is not denatured and maintains natural keratin protein conformation, and
- wherein at least about 30% of the keratin protein exhibits a molecular weight of at least about 443 KDa.
4 more elements
A method of repairing or strengthening the skin of a mammal comprising the step of
- applying a keratin protein cosmetic composition topically to contact and coat all exposed surfaces of the skin in need of treatment thereby repairing or strengthening the skin of the mammal,
- wherein the keratin protein cosmetic composition comprises:
- at least one keratin protein derived from human hair;
- and
- a cosmetic base solution,
- wherein the keratin protein is not denatured and maintains natural keratin protein conformation, and
- wherein at least about 30% of the keratin protein exhibits a molecular weight of at least about 443 KDa.
