Why This Works for Your Specific Profile
Damage Index:
Damage levels outside specified range may not benefit optimally from product formulation
Water Quality:
Fine hair becomes weighed down and greasy from heavy formulation
Hair:
Closed cuticles resist product penetration causing surface buildup without internal benefits

Ingredients Overview
Ingredients List
amino-acids, ceramide-ng, ceramide-np, cholesterol, dicokoylethylhydroxyethylmonium-methosulfate, soybean-sterol, palmitic-acid, isostearoyl-hydrolyzed-collagen-ampd, diglucosyl-gallic-acid, white-fungus-extract, polyquaternium-51

Ingredients Details
Cholesterol
Common Name(s): 5-cholesten-3-ol,cholesterin
CAS Number: 57-88-5
DESCRIPTION
What It Does: Provides essential barrier sterol function as one of three critical stratum corneum lipid components.
Why It's Used: Essential component of complete barrier repair formulations โ the stratum corneum barrier requires ceramides:cholesterol:fatty acids in approximately 1:1:1 molar ratio for complete barrier restoration.
How It Works: Integrates between ceramide headgroups in lamellar body structures, providing fluidity and flexibility to the otherwise rigid ceramide-dominated lipid matrix. controls lamellar body phase behavior for functional barrier.
Typically Found In: Barrier repair moisturizers,eczema treatments,dry skin formulations
TECHNICAL DETAILS
Primary Category: Active ingredient โ barrier sterol
Secondary Functions: Lamellar body structure,barrier sterol
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01%โ1%
SOURCING & ETHICS
Vegan Status: Conditional โ animal-derived (lanolin) or plant-derived phytosterol analogs; verify
Halal Status: Conditional โ verify source
Source Notes: Traditionally from lanolin (wool grease). plant-derived cholesterol alternatives include phytosterols, though these show slightly different barrier integration. verify for vegan/halal.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Endogenous molecule; excellent tolerability.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Exceptional safety profile. natural skin component. ewg score: 1.
Works Well With: Other ceramides,cholesterol,free fatty acids,hyaluronic acid,niacinamide
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Elias demonstrated that barrier repair requires all three lipid classes (ceramides, cholesterol, fatty acids) in approximately equimolar ratios. formulations providing only ceramides without cholesterol and fatty acids show significantly inferior barrier restoration vs complete triple-lipid combinations.

Polyquaternium-51
Common Name(s): Polyquaternium-51,cationic conditioning polymer,substantive film-former
CAS Number: N/a
DESCRIPTION
What It Does: Deposits a conditioning film on hair and skin through electrostatic attraction to negative cuticle/corneocyte surfaces, reduces hair-on-hair friction for improved combability and detangling, eliminates static charge buildup, and provides anti-frizz humidity resistance.
Why It's Used: Cationic polymers are the primary hair conditioning technology โ the permanent positive quaternary ammonium groups provide substantive deposition that resists rinsing, delivering persistent conditioning between washes unlike small-molecule cationic conditioners.
How It Works: At shampoo/conditioner ph 4.5โ5.5, hair cuticle carries net negative charge (isoelectric point ph ~3.5). polyquaternium cations undergo electrostatic attraction depositing on the cuticle surface. during rinsing, the deposited polymer film persists from reduced surface-solution equilibrium at low bulk concentration โ substantive deposition from favourable interfacial versus bulk partitioning.
Typically Found In: Shampoos,conditioners,leave-in products
TECHNICAL DETAILS
Primary Category: Active ingredient โ cosmetic active
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care

Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ3%
SOURCING & ETHICS
Vegan Status: Yes
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
Different polyquaternium numbers indicate different backbone chemistries: pq-7 (acrylamide/quaternary acrylate copolymer) for leave-on flexibility; pq-10 (hydroxyethylcellulose/quaternary ammonium) for substantive deposition; pq-11 (vp/dimethylaminoethyl methacrylate) for styling fixation.
