For a Hair & Scalp Formulation Lead developing for colour-treated, difficult-to-manage hair
What can a hair-fibre precedent tell you about the product on the bench?
The archive contains ex-vivo hair-fibre testing and two 28-day finished-product evaluations. We keep each result tied to format, concentration and evidence level, then define what the next prototype must prove.

What are you here to decide?
Choose the decision closest to yours. Product opportunity, technical evidence and strategic fit stay connected—but the next step changes by role.
01 · From lived moment to product route
Hair & Scalp is not one promise. It is a sequence of very different human moments.
The folder spans daily washing, detangling, intensive fibre care and a still-open scalp route. We make those possibilities tangible without turning strand data into a scalp or hair-growth claim.
01 · Human moment
A person with colour-treated hair trying to make the daily wash feel less demanding
A wash ritual that still feels caring
Problem to solve
They want clean hair without a formula that feels visually heavy, difficult to rinse or hard to manage afterwards.
What happens if it stays unresolved
If colour, foam and rinse profile are solved separately, the concept can feel distinctive on screen but disappointing in use.
How we help
Build a shampoo route around the complete surfactant system, colour distribution, foam perception, rinse profile and a finished-formula sensory test plan.

Low-residue wash
02 · Human moment
A person detangling bleached, white or colour-treated lengths
An intensive fibre-care moment
Problem to solve
They want easier handling and a deliberate treatment ritual without another generic repair promise.
What happens if it stays unresolved
A striking mask can be memorable yet still fail on distribution, combability or the evidence needed for the intended communication.
How we help
Use the 5% AHE hair-mask fibre precedent to frame a new mask or conditioner prototype and define the exact instrumental or sensory endpoint it must validate.

Conditioner
03 · Human moment
A person who gives the scalp its own pre-wash care step
A scalp ritual that needs its own proof
Problem to solve
The experience may feel relevant, but hair-fibre data cannot answer a human scalp question.
What happens if it stays unresolved
If the evidence levels are blurred, a promising scalp concept can drift into unsupported comfort, dandruff or hair-growth language.
How we help
Shape the pre-wash or scalp-mask experience first, then build a separate finished-product human scalp validation route around the intended use and market.

02 · For the formulation owner
A category without an exact format hides the next technical problem.
We make four possible starting points tangible so the team can choose what to prototype. They are not universal compatibility or dosage recommendations.

Make the format visible before discussing performance.
Problem to solve
AHE can change colour, foam perception, deposition and rinse behaviour differently in every surfactant or conditioning system.
The folder includes a marketed shampoo concept evaluated with and without 0.3% AHE. That precedent can guide the next bench discussion, but the whole base, process, fragrance system and package still determine the finished experience.

04 · For the Hair & Scalp R&D lead separating scalp biology from fibre performance
Two routes must stay separate: scalp biology and hair-fibre mechanics.
The folder offers a broad Hair & Scalp hypothesis. The strongest direct evidence is narrower: a hair-mask fibre test and finished shampoo or conditioner user evaluations.
04 linked research layersOpen the technical mechanism mapApplication bridge, tested contexts and evidence boundary
Problem to solve
The folder places scalp hydration, microbial balance, hair growth and fibre flexibility in one application world although they require different models and proof.
What happens if it stays unresolved
Ex-vivo strand mechanics or biomarker themes can be misread as human scalp efficacy, hair-growth support or treatment of a scalp condition.
How we help
We divide the story into two biological question spaces and two direct finished-product or fibre precedents.

Application bridge
The fibre test can inform a new mask test plan; the user evaluations can inform shampoo or conditioner sensory questions. Neither establishes a biological hair-growth or scalp-treatment mechanism.
Evidence boundaryWhat this map cannot claimOpen boundary
No hair-growth, anti-hair-loss, dandruff, psoriasis or dermatitis claim is established. Fibre mechanics, user perception and human scalp efficacy remain separate evidence routes.
05 · Tested contexts at a glanceThree product contexts—not one universal Hair & Scalp claim.Open the compact context map
01 · Ex-vivo fibre context
5% AHE hair mask
What was explored
Base hair mask with and without 5% AHE, applied once to 25 bleached and 25 white hair fibres.
What was measured
Tensile behaviour at defined extension and Young's modulus were included as instrumental fibre endpoints.
Evidence boundary
This is not a human clinical or scalp study and does not establish reduced breakage, repair or hair growth in people.
02 · Human-use interview context
0.3% AHE shampoo
What was explored
A marketed shampoo base with and without 0.3% AHE was used over 28 days by 20 people with dyed or colour-treated hair.
What was measured
Selected sensory, manageability and hair/scalp-perception questions were assessed through interviews.
Evidence boundary
The exact design, scale, item-level data and primary report must be verified before numerical or objective efficacy claims are published.
03 · Formula-mapping gate
0.3% AHE conditioner
What was explored
A conditioner concept with and without 0.3% AHE was evaluated over 28 days in a 20-person colour-treated-hair context.
What was measured
Texture, shine, detangling, perceived strength and manageability were included in the interview map.
Evidence boundary
The folder shows only one surfactant-led INCI list for shampoo / conditioner; the exact conditioner formula must be reconciled before public result use.
Controlled archive: Instrumental charts, interview graphics and a marketed-base INCI list are available. Skin-mask and facial-cleansing pages copied into the Hair folder are not treated as Hair & Scalp evidence.
06 · For the technical reviewer who needs the complete context
The useful depth is available through a controlled, project-matched route.
Public orientation stays short. Formula, protocol, rights and release details remain available through the qualified technical route.
Controlled depthOpen the technical handover criteriaFormula, protocol, rights and release status
Problem to solve
Archived values or volunteer images without the exact formula, protocol and permissions can create a false shortcut.
What happens if it stays unresolved
A finished-formulation observation may be repeated as an ingredient-only claim or used for a differently built prototype.
How we help
We match the application, market and formulation question to the current technical record and disclose only the material that has passed formula, claim and rights review.
Qualified technical routePrimary reports, numerical readouts and participant imagery are supplied only where the current release and rights status permits.
07 · For the team deciding the next validation step
A result without its tested formula can misdirect the next prototype.
We keep the formula boundary visible. Public results are shown only when the tested formula and AHE context are sufficiently mapped; controlled results remain in the qualified dossier route.
Ex-vivo + finished-formula human-use context
Three tested contexts answer three different development questions.
A base hair mask with and without 5% AHE was instrumentally assessed on bleached and white hair fibres after one application. Separate 28-day evaluations compared marketed shampoo and conditioner concepts with and without 0.3% AHE in people with colour-treated hair. The detailed outcomes remain controlled until the primary reports, scales and exact formulas are reconciled.
