Hydrolyzable Silk Peptide Powder Cosmetic Grade Silk Peptide For Hair Serum

The term "silk peptide" is often used interchangeably with "hydrolyzed silk amino acids."

Silk peptide is the product obtained by hydrolyzing (breaking down) larger silk proteins derived from silkworm cocoons into smaller, water-soluble peptide chains and amino acids . It is typically produced as a light gray to grayish-brown powder.

Silk peptide, derived from hydrolyzed silk protein (specifically from fibroin and sericin), works in two primary ways to improve hair health and appearance.

Penetrative Repair (Internal): Low molecular weight silk peptides (e.g., 300-500 molecular weight) can effectively penetrate the hair shaft, particularly in hair that has been damaged by chemical treatments . Once inside, they help increase hair weight, thickness, and moisture content, fundamentally recovering the hair's normal condition .

Protective Film (External): Silk peptides, especially those from sericin, have a strong affinity for hair and form a smooth, transparent, protective film on the surface . This film improves hair's gloss and elasticity and effectively prevents further damage.
