hiustenvalkuaisia
Hiustenvalkuaisia, often translated as hair proteins, refers to the primary structural component of hair. The most abundant and significant of these is keratin, a fibrous protein that gives hair its strength, elasticity, and texture. Keratin is a complex molecule composed of amino acids, with cysteine playing a crucial role due to its sulfur-containing side chains. These side chains form disulfide bonds, which are strong chemical cross-links that hold the keratin chains together and determine the hair's shape and resilience.
The structure of hair proteins is organized into several layers. The cuticle, the outermost layer, is made
Damage to hair proteins, whether from heat styling, chemical treatments, or environmental factors, can lead to
