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:
Soft or moderately hard water does not require intensive treatment causing over-cleansing and dryness
Hair:
Closed cuticles resist product penetration causing surface buildup without internal benefits
Active Lifestyle:
Activity levels outside optimal range affect product performance and maintenance requirements

Ingredients Details
Hydrolyzed Keratin
Common Name(s): Keratin peptides,soluble keratin,hydrolyzed wool protein
CAS Number: 69430-36-0
DESCRIPTION
What It Does: Repairs hair structure by penetrating and rebonding with damaged hair keratin proteins.
Why It's Used: The authentic hair repair ingredient โ same protein composition as hair itself, providing structural repair from within the cortex rather than surface coating alone.
How It Works: Hydrolyzed keratin peptides (500-2000 da) penetrate cuticle and cortex. cysteine thiol groups form disulfide bonds with oxidized keratin (rebonding). cross-links damaged cortex protein for improved tensile strength and reduced breakage. surface film formation fills cuticle gaps.
Typically Found In: Damage repair conditioners,hair masks,professional treatments
TECHNICAL DETAILS
Primary Category: Active ingredient โ keratin peptide
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%โ10%
SOURCING & ETHICS
Vegan Status: Conditional โ from wool (ovis aries) keratin; plant alternatives limited
Halal Status: Conditional โ wool source; verify halal certification
Source Notes: From hydrolyzed wool or feather keratin. plant-based (wheat keratin analog) available but different amino acid profile. marine keratin from squid pen also available.
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
Hair keratin is unique in its high cysteine content (~14%) forming extensive disulfide bond crosslinks. these disulfide bonds are disrupted by bleaching, heat, and chemical processing. hydrolyzed keratin's cysteine groups physically rebond into these disrupted sites โ a structural repair mechanism specific to keratin chemistry not achievable with any other protein hydrolysate.

Parfum
Common Name(s): Parfum,parfum,cosmetic functional ingredient,established cosmetic active
CAS Number: N/a
DESCRIPTION
What It Does: Provides the characteristic cosmetic function of its ingredient class through its molecular chemistry at recommended use concentration.
Why It's Used: Parfum is selected for the specific functional properties of its molecular class โ the chemical architecture of parfum delivers the required cosmetic performance through documented interactions with skin biology and formulation matrix.
How It Works: The functional groups interact with formulation components and skin surfaces through h-bonding, ionic association, surface adsorption, or receptor activity as appropriate to the molecular class.
Typically Found In: Cosmetic formulations

Polyquaternium-10
Common Name(s): Pq-10,hydroxyethylcellulose ethyl trimethylammonium chloride,jr-400
CAS Number: 54351-50-7
DESCRIPTION
What It Does: Provides film-forming conditioning and detangling with heat protection in a polymer that adsorbs substantively to hair.
Why It's Used: The most widely used cationic polymer conditioner โ provides excellent conditioning and detangling while adsorbing strongly to damaged hair areas that need conditioning most.
How It Works: Cationic quaternary ammonium groups along the polymer backbone adsorb to anionic sites on hair keratin. higher charge density on damaged hair (more negative sites) leads to preferential adsorption where conditioning is needed. polymer film formation provides heat protection and volume.
Typically Found In: Shampoos,2-in-1 products,conditioners,styling products
TECHNICAL DETAILS
Primary Category: Functional ingredient โ cationic polymer conditioner
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ2%
SOURCING & ETHICS
Vegan Status: Yes โ cellulose-derived
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
Polyquaternium-10's 'self-targeting' to damaged hair sites is a unique smart conditioning mechanism. as hair damage increases negative charge density by exposing keratin's aspartate and glutamate carboxylate groups, pq-10's cationic polymer backbone adsorbs preferentially to these high-charge damage sites โ automatically delivering more conditioning where the hair needs it most.
