Keratin is the secret ingredient behind many haircare products, known for its remarkable ability to repair and strengthen hair. Let's dive into the science of keratin and understand how it works its magic on your locks.
Here Is The Science of Keratin: How It Repairs and Revives Damaged Hair
- What Is Keratin?
Keratin is a fibrous protein naturally found in the hair, skin, and nails. In hair, it forms a protective layer that keeps it strong, flexible, and healthy. - Hair Structure
Hair is composed of three layers: the cuticle (outer layer), cortex (middle layer), and medulla (inner layer). Keratin is primarily found in the cortex and cuticle. - Protein Bonds
Keratin contains amino acids linked by protein bonds. These bonds are responsible for hair's structure and strength. - Damage and Breakage
Daily activities, heat styling, and chemical treatments can damage these protein bonds, leading to hair breakage, frizz, and dullness. - How Keratin Repairs Hair
Keratin hair products, like masks and treatments, typically contain hydrolyzed keratin. This form of keratin has smaller molecules that can penetrate the hair shaft.
