Silk Protein
What is Silk Protein?
Silk Protein originates from the cocoons of the silkworm Bombyx mori, consisting mainly of fibroin, a fibrous protein rich in amino acids similar to those in human keratin. In cosmetics, it appears as hydrolyzed silk peptides, categorized primarily as a hair conditioning agent but also used in skin products. It works by adhering to the hair shaft, creating a lightweight film that smooths the cuticle surface, locks in moisture, and reduces friction between strands. This action enhances hair's natural sheen, detangles, and fortifies weakened areas prone to damage. As a humectant, it attracts water to maintain hydration levels on hair and scalp. Its biocompatibility allows partial penetration into the cortex, aiding in repair-like effects for processed or environmentally stressed hair without buildup.
