Keratin Protein

1. Definition Keratin Protein:

Keratin protein is a fibrous structural protein that makes up the outer layer of human skin, hair, and nails. It is known for its strengthening and protective properties.

2. Use:

Keratin protein is commonly used in cosmetics and hair care products to strengthen and repair damaged hair. It helps to restore the natural structure of the hair, making it smoother, shinier, and more resilient to damage. In skincare products, keratin protein can help improve the skin's elasticity and firmness, making it appear more youthful and healthy.

3. Usage Keratin Protein:

When using cosmetics or hair care products containing keratin protein, it is important to follow the manufacturer's instructions carefully. It is recommended to use these products as directed and to avoid overuse, as excessive use may lead to buildup on the hair or skin. It is also important to perform a patch test before using products containing keratin protein to check for any potential allergic reactions.
