The brief.
Origin
Silk cocoons from Chinese and Korean sericulture, hydrolysed and standardised in South Korean cosmetic-biotech facilities to guarantee peptide weight.
Extraction
Cocoons are degummed to isolate fibroin (the structural protein β sericin is the gum), then enzymatically hydrolysed to a controlled 500β1,200 Da range.
Sustainability
Peace Silk protocols allow moths to emerge before cocoon harvest, addressing the ethical concern. Cocoons are otherwise agricultural by-products.
How it works.
Hydrolysed silk peptides deposit in a thin, water-resistant film along the cuticle. Their block-copolymer structure (alternating hydrophilic and hydrophobic domains) lets them bond to damaged patches while remaining flexible enough to move with the strand β the reason silk-treated hair looks glossy but never crunchy.
Delivers
- 01Coats and smooths the cuticle for a mirror-like finish
- 02Adds tensile strength to bleach-weakened strands
- 03Improves colour retention by sealing porosity
- 04Lightweight β no protein-overload stiffness

Heritage.
The record
Sericulture began in China around 3,600 BCE; hydrolysed silk peptides for cosmetic use were commercialised in Japan and Korea in the 1970sβ80s as an alternative to animal-derived collagen.
Traditional use
Chinese and Japanese silk-water hair rinses; Ayurvedic silk-fibre scalp massage.

People often ask.
Hydrolyzed silk vs silk amino acids?
Silk amino acids are the smallest fragments (single amino acids and dipeptides); hydrolysed silk is a slightly larger peptide range that films the cuticle. We use both for complementary repair.
