Amino acids β matching the profile of human hair keratin
The brief.
Origin
Hydrolysed from cocoons of Bombyx mori silkworms cultivated in the Yangtze delta, where sericulture has been practised for 5,000 years.
Extraction
Cocoons are degummed, dissolved in a mild alkaline bath, then enzymatically hydrolysed to release low-molecular-weight peptides (300β1,000 Da) able to penetrate the cuticle.
Sustainability
Our supplier participates in the Peace Silk protocol β moths are allowed to emerge before harvest, breaking the historic ethical concern. Cocoons are otherwise agricultural by-products.
How it works.
Silk peptides have a lower molecular weight than most hydrolysed proteins, so they diffuse through the cuticle and bond with damaged sites in the cortex. Because silk's amino-acid profile is closer to human keratin than any other protein source, the repair feels natural β soft, not stiff.
Delivers
- 01Delivers 18 hair-identical amino acids for internal repair
- 02Adds slip and detangling without protein overload
- 03Silk peptides bind excess UV β mild photo-protection
- 04Improves elasticity for less breakage during styling
Molecular signature.
The bio-active constituents that make Silk Amino Acids work β with standardised percentages where measured by HPLC.
- 01
Glycine + Alanine + Serine
The three amino acids that make up 80% of silk fibroin β small, penetrating, humectant.
- 02
Tyrosine
UV-absorbing amino acid that adds photo-protection.

Heritage.
The record
Silk fibres appear in Chinese archaeological records from 3,600 BCE, and silk-water hair rinses were court beauty rituals under the Tang and Song dynasties. Modern hydrolysed silk peptides were commercialised in Japan in the 1970s.
Traditional use
Chinese imperial hair rinse; Japanese silk-cocoon face and hair mask; Ayurvedic silk-fibre scalp massage.
Naturally found in
- Bombyx mori silkworm cocoons
- Sericulture traditions across China, Japan, India, Thailand

People often ask.
Silk vs keratin β which is better?
Silk is lighter and more penetrating; keratin has a stronger structural profile. We use both, at different doses, for balanced repair without stiffness.
Is silk peptide vegan?
No β it is derived from silkworm cocoons. Our supplier uses Peace Silk protocols, but strict vegans should choose our hydrolysed-keratin-only formulas.
