Hair ageing and longevity
Established clinical focusExplore the relationship between ageing, follicular change, density, shaft quality and long-term preservation.

Science and Clinical Research
Building a clearer understanding of hair loss over time
Hair Longevity Institute brings together trichology, clinical imaging, structured assessment and longitudinal observation to support better questions, better evidence and more informed care.
Scientific approach
Evidence begins with consistent observation
A single image can show appearance. Longitudinal evidence helps show change. Observation alone does not prove causation; interpretation remains clinical and contextual.
- Structured clinical history
- Consistent photography protocols
- Trichoscopy where appropriate
- Treatment context and timelines
- Repeated observation over time
- Separation of reported and observed information
- Careful, qualified interpretation
- Referral or further investigation where required
Research areas
Questions HLI engages with in clinical practice and observation
Status labels distinguish established clinical focus from observational programmes, exploratory hypotheses and verified publication. Active research is only claimed where current activity exists.
Androgenetic alopecia
Established clinical focusInvestigate patterns, progression, miniaturisation, treatment response and long-term planning.
Female pattern hair loss
Established clinical focusExplore presentation, differential considerations, hormonal context, treatment response and under-recognised variation.
Trichoscopy and imaging
Observational programmeStudy how structured clinical imaging may support assessment, documentation and monitoring.
Donor preservation and hair restoration
Established clinical focusExplore donor management, procedural planning, long-term donor integrity and outcome assessment.
Regenerative approaches
Exploratory hypothesisEvaluate clinical use, evidence quality, patient selection, limitations and longitudinal response—without implying guaranteed regeneration.
Scalp health and inflammation
Established clinical focusExplore the relationship between scalp environment, symptoms, shedding and treatment tolerance.
Longitudinal outcomes
Observational programmeBuild structured evidence across treatment, surgery, monitoring and patient-reported experience.
Trichoscopy
Trichoscopy as part of the clinical picture
Where appropriate, structured clinical imaging may help clinicians observe shaft and scalp features that plain photography alone can miss. Findings still require history, context and professional judgement.
- Shaft diameter variation
- Miniaturisation patterns
- Follicular openings
- Density patterns
- Scalp surface changes
- Treatment response over time
- Progression documentation
Clinical trichoscopy imagery is shown publicly only when ownership, consent and approval are confirmed. Until then, this section remains text-led with governed placeholders—not stock imagery presented as patient evidence.
Longitudinal evidence
Moving from isolated appointments to continuous evidence
Hair-health decisions improve when baselines, intervals and treatment context are documented consistently—without publishing proprietary system internals.
- Baseline documentation before change is assumed
- Standardised follow-up intervals where appropriate
- Treatment timelines and adherence context
- Symptom tracking alongside imaging
- Consistent image roles and comparable views
- Observed-versus-expected clinical comparison
- Interpretation under clinical governance

Published and formal work
Verified records only
Manuscripts, drafts and concepts are not listed as publications. Where repository content cannot verify a record, the item remains pending external confirmation.
| Title | Type | Status | Significance |
|---|---|---|---|
| Partial Transection Technique (historical work associated with Paul Green)No official link until verified | Educational / technical contribution — exact publication status pending confirmation | Pending external confirmation | May relate to hair-restoration technical practice. Exact title, venue, year and peer-review status require external confirmation before presentation as published formal work. |
Peer-reviewed publication claims, conference presentations, registered studies and patents are added only after title, venue, year and link are confirmed. HLI does not present unpublished internal work as published science.
Research governance
Research with clinical responsibility
- Ethical handling of patient information
- De-identification where research use requires it
- Consent for permitted purposes
- Data minimisation
- Controlled access to clinical material
- Clinical oversight of interpretation and use
- Separation of individual care from research use
- No unrestricted re-identification
- No research use beyond permission
- Responsible, evidence-qualified communication of findings
Governance claims here describe principles adopted for public communication. Implementation detail that would weaken security is intentionally omitted.
Connected ecosystem
Research supported by a connected clinical ecosystem
The wider Follicle Intelligence.ai ecosystem is designed to support continuity across assessment, care, education and outcome review. Individual systems are not claimed to exchange data unless that integration is implemented and verified.
