shampoo
Enable an agent to recognise shampoo, assess its suitability and condition, and determine how it may be used to clean hair and scalp.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an agent to recognise shampoo, assess its suitability and condition, and determine how it may be used to clean hair and scalp.
Shampoo is a formulated cleansing product intended primarily to remove sebum, accumulated products and other soil from hair and scalp, usually through surfactant action followed by rinsing.
It can be Classify a candidate product as shampoo or flag an unresolved boundary case.; Compare formulations against declared hair, scalp and user requirements.; Retrieve and apply product-specific dosing, contact-time and rinsing instructions.; Identify documented sensitivities, restrictions or missing suitability evidence.; Assess cleansing and additional claims against their evidence and test conditions.; Flag condition or dispensing problems that require withholding use or replacing the product..
Distinguishing features
The product's stated purpose includes cleansing hair or scalp; conditioning or styling alone does not establish shampoo identity.
Hair or scalp application is explicit in the intended use; a body cleanser is not automatically shampoo because it can produce foam.
The model distinguishes cleansing intended to remove soils during rinsing from products intended to absorb or conceal oil between washes.
A solid format does not exclude shampoo identity; intended application and cleansing formulation distinguish a shampoo bar from a generic soap bar.
An anti-dandruff or similar claim is recorded separately from shampoo identity, with its supporting evidence and jurisdictional status left explicit.
Scope
+ Identity and boundaries of products intended to clean hair and scalp
+ Cleansing formulation, product format and rinse requirements
+ Suitability for intended hair, scalp and user groups
+ Application instructions and evidence for cleansing or additional claims
+ Formulation stability, contamination indicators and dispensing conditions
- Hair and scalp anatomy as independent biological models
- Diagnosis and treatment planning for scalp diseases
- Conditioner, hair masks, styling products and body cleansers except at product boundaries
- Ingredient substances as independent chemical models
- Packaging manufacture and waste infrastructure
- Brand organisations, commercial product lines and individual inventory records
Characteristics
- Product format
- liquid; gel; cream; solid bar; powder; aerosol; other declared format Determines how the product is dosed, applied, stored and assessed at the shampoo boundary.
- Cleansing and removal route
- wash-and-rinse; no-rinse cleansing; oil absorption followed by removal; other; unresolved Separates application pathways and flags products whose inclusion requires a registry boundary decision.
- Declared cleansing system
- Links to declared cleansing ingredients and documented roles; concentrations where available Supports assessment of how the formulation cleans without inferring performance from one ingredient.
- Measured pH
- dimensionless pH, with sample preparation, dilution, temperature and method Allows meaningful comparison when a pH measurement is applicable and prevents comparison of incompatible test conditions.
- Intended hair and scalp context
- Manufacturer-declared hair condition, scalp condition, chemical treatment and user group; unspecified Connects intended use to the person or situation being assessed without assuming universal suitability.
- Declared sensitivities and restrictions
- Links between ingredients, documented user sensitivities, label warnings and use restrictions Supports identification of known conflicts and uncertainty before use.
- Application amount
- g or mL per application, or a labelled qualitative amount when no quantitative amount is supplied Makes dosing instructions actionable while retaining the limits of the available directions.
- Specified contact time
- seconds or minutes, with associated instruction and claim; not specified Prevents an agent from inventing a dwell time or transferring one product's instructions to another.
- Claim support
- claim recorded; evidence unavailable; evidence reviewed; supported within stated conditions; unresolved Keeps marketing language distinct from demonstrated performance.
- Usability condition
- within documented conditions; visibly changed; suspected contamination; outside labelled period; unknown Supports a use, hold or replacement decision without treating appearance as proof of microbiological safety.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 19 findings · 29 questions.
Shampoo identity Establishes the cleansing purpose and product boundaries of shampoo.
Hair-care names and formats alone do not establish which products this registry entry should cover.
Intended cleansing role
Records where the product is applied and what cleansing task it claims to perform.
Hair and scalp cleansing purpose
Record the declared cleansing purpose and distinguish it from conditioning, fragrance and styling functions.
- What product description or directions establish that it is intended to clean hair or scalp? definition
- Which functions establish shampoo identity, and which are additional claims? boundary
Formats and neighbouring products
Resolves boundaries involving bars, dry shampoo, no-rinse products and combined cleansers.
Format-independent membership
Assess membership through intended use and cleansing route, recording unresolved registry boundaries explicitly.
- Does this entry include dry shampoo and no-rinse formulations, or are they neighbouring kinds? boundary
- What distinguishes a candidate shampoo bar or combined hair-and-body wash from a generic soap or body cleanser? definition
Cleansing formulation Records the formulation information needed to understand cleansing and delivery.
Shampoo suitability and performance depend on the complete formulation and use conditions.
Cleansing ingredients
Connects declared ingredients to documented cleansing roles.
Documented cleansing system
Record the cleansing ingredients, their supported roles and any limits imposed by undisclosed concentrations.
- Which declared ingredients perform cleansing, and what documentation supports those roles? provenance
- Which formulation details needed to assess cleansing are unavailable from the ingredient declaration? boundary
Formulation behaviour
Captures measurable properties relevant to application and rinsing.
Use-relevant properties
Record applicable pH, flow, dissolution and dispersal observations with their test conditions.
- How were pH and any relevant flow or dissolution properties measured for this format? measurement
- How does the formulation disperse during application and leave the hair during its specified removal step? measurement
Hair and scalp suitability Relates a shampoo's intended use and restrictions to the application context.
An agent needs more than a broad hair-type label to assess whether use is appropriate.
Intended user context
Records declared suitability for hair conditions, scalp conditions and user groups.
Supported suitability
Separate manufacturer targeting from evidence for suitability under particular conditions.
- Which hair conditions, scalp conditions, treatments and user groups does the product explicitly address? definition
- What evidence supports suitability for those contexts, and which contexts were not assessed? provenance
Sensitivities and use limits
Captures documented ingredient conflicts and application restrictions.
Documented use conflicts
Record label restrictions and known user sensitivities without inferring that an unreported conflict is absent.
- Do declared ingredients or label restrictions conflict with a documented user sensitivity or intended application? boundary
- What do product-specific directions say to do if irritation or unintended exposure occurs? action
Washing and claim evidence Connects application steps to cleansing outcomes and additional claims.
An agent must distinguish following directions from establishing that a claimed outcome has been demonstrated.
Application sequence
Records the steps and conditions specified for use.
Product-specific washing instructions
Capture hair wetting, dose, distribution, contact time, removal and frequency where specified.
- What application sequence, amount, contact time and removal method do the directions specify? action
- Which instructions change with hair length, soil load or frequency of use, and which are unspecified? boundary
Cleansing and additional outcomes
Separates measured cleansing performance from sensory impressions and additional claims.
Claim-specific evidence
Record each claim with its outcome measure, evidence source and conditions, including any jurisdiction-dependent classification.
- What measurements support cleansing or additional claims, using which comparator and application conditions? measurement
- For claims such as dandruff control, what authoritative product and jurisdiction records establish their status? provenance
Shampoo condition and storage Assesses whether the formulation remains usable under its storage and dispensing conditions.
Water exposure, storage and repeated dispensing can affect the condition of shampoo in use.
Stability and use period
Connects labelled storage and time limits to observed formulation condition.
Condition against documented baseline
Assess changes in appearance, odour, texture or performance against product documentation rather than assuming every change indicates spoilage.
- What storage conditions and unopened or after-opening periods are documented for the product? provenance
- Which observed changes are documented as expected, and which leave usability unresolved? boundary
Water exposure and dispensing
Records handling conditions relevant to dilution, contamination and solid-product drying.
Handling-dependent condition
Capture water ingress, user dilution, refilling and bar storage where they affect the documented use conditions.
- Has water ingress, dilution, refilling or prolonged wet storage changed the product from its documented condition? provenance
- What product-specific handling or replacement action is justified when those conditions are unknown or exceeded? action

What the second pass must settle
- Does an existing Vercy world model already cover shampoo, requiring this registry entry to link to that source of truth?
- Should vr.tr.shampoo include dry shampoo, no-rinse cleansers, animal shampoos and combined hair-and-body products, or does the registry place any of these elsewhere?
- Which authoritative sources and reproducible methods should anchor cleansing, rinsability, residue and hair or scalp compatibility assessments?
- Which formulation details can reliably be obtained beyond ingredient declarations, particularly concentrations and preservation or stability evidence?
- How should jurisdiction-dependent medicinal or therapeutic claims be represented while preserving a single shampoo concept?
