Hair keratin is the fundamental protein that forms the structural integrity of each strand, acting as the primary building block that determines strength, resilience, and overall appearance. Individuals with high-porosity hair often benefit from more frequent protein treatments, whereas those with low porosity may require lighter protein formulas or moisture-focused care to avoid buildup and maintain softness.

This depletion is why damaged hair often feels mushy or straw-like; the structural matrix is compromised. The Science of Hair Keratin At a molecular level, keratin is a type of fibrous structural protein rich in sulfur-containing amino acids, particularly cysteine.
How It Protects the Hair Shaft The primary function of this protein on the surface of the hair is to act as a shield. Understanding its role is essential for anyone looking to improve the health and appearance of their hair, as it influences everything from texture to growth cycles.
