KERATIN

Description

Keratin is a fibrous protein that forms the structural foundation of hair, nails, and the outer layer of skin. As a key component in haircare formulations, keratin plays a crucial role in strengthening and protecting hair strands. This naturally occurring protein is composed of long chains of amino acids, primarily cysteine, which form strong disulfide bonds.

In haircare products, keratin is often used to repair damaged hair, improve elasticity, and enhance overall hair health. It works by penetrating the hair shaft, filling in gaps and smoothing the cuticle. This process can lead to reduced frizz, increased shine, and improved manageability. Keratin treatments and products are particularly beneficial for individuals with dry, brittle, or chemically treated hair.

The effectiveness of keratin in haircare formulations depends on the molecular weight and processing method used. Hydrolyzed keratin, with smaller molecules, can more easily penetrate the hair shaft. When combined with other ingredients like panthenol or silk amino acids, keratin can provide synergistic benefits for hair strength and moisture retention. However, it's important to note that while keratin can temporarily improve hair appearance and texture, it does not permanently alter hair structure.
