Keratin is a fibrous structural protein that is naturally found in the hair, skin, nails, and other tissues in the human body. In hair care products, amino acids derived from keratin are often used to strengthen, repair, and improve the overall health and appearance of the hair.

Structural Component: Keratin is a major structural component of the hair shaft. It forms a protective barrier around the hair, helping to maintain its strength, elasticity, and integrity. Amino acids derived from keratin can penetrate the hair shaft, reinforcing its structure and filling in gaps or damaged areas.

Repair and Reconstruction: Amino acid keratin works by binding to the hair’s natural keratin, replenishing lost protein and repairing damage caused by environmental factors, heat styling, chemical treatments, and mechanical stress. By repairing damaged areas of the hair shaft, keratin amino acids help restore smoothness, shine, and manageability to the hair.

 Keratin amino acids strengthen the hair by forming cross-links with other proteins in the hair shaft. This reinforcement increases the hair’s resistance to breakage, split ends, and damage

Hair Smoothing: When applied to the hair, glyoxylic acid(in a complex with other ingredients) can help smooth out frizz and reduce curl or wave patterns. It achieves this by restructuring the protein bonds in the hair, allowing it to lay flatter and appear smoother. This effect is particularly beneficial for individuals with curly or frizzy hair who desire a sleeker, more manageable look.

In addition to smoothing, glyoxylic acid treatments can also provide a temporary straightening effect.
