Why This Works for Your Specific Profile
Damage Index:
Healthy to moderately damaged hair experiences over-conditioning or protein overload causing limpness or rigidity
Water Quality:
Hair with breakage or thinning needs protein emphasis that moisture-heavy formula lacks
Hair:
Closed cuticles resist product penetration causing surface buildup without internal benefits
Active Lifestyle:
High activity and frequent washing rapidly strip product benefits requiring excessive reapplication

Ingredients Details
Lysine
Common Name(s): 2,6-diaminohexanoic acid,l-lysine hcl
CAS Number: 56-87-1
DESCRIPTION
What It Does: Provides collagen crosslink precursor activity and nmf conditioning from the essential diaminoamino acid.
Why It's Used: Collagen crosslink amino acid โ lysine's hydroxylation to hydroxylysine and subsequent cross-link formation via lysyl oxidase provides the structural crosslinks that give collagen mechanical strength.
How It Works: Converted to hydroxylysine by lysyl hydroxylase. hydroxylysine provides collagen crosslink sites for lysyl oxidase-catalysed aldehyde cross-links. nmf amino acid component. basic amino acid (ฮต-amino group pka 10.5) provides antimicrobial cationic character. antiviral via competition with arginine (essential for herpes virus replication).
Typically Found In: Collagen-support products,antiviral skin care,nmf products
TECHNICAL DETAILS
Primary Category: Active ingredient โ essential amino acid
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.5%โ5%
SOURCING & ETHICS
Vegan Status: Yes โ fermentation
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Lysine's antiviral activity for herpes simplex virus is pharmacologically validated: hsv replicates using arginine as a structural protein component, while lysine competes with arginine for cellular uptake via the same transporter. high lysine:arginine ratio reduces viral protein synthesis โ the basis for the clinical practice of high-lysine dietary supplementation and topical application for cold sore prevention.
