Personalised analysis backed by biology, not guesswork.
No referral required · Typically 48 hours to your personalised plan
Three simple steps to your personalised plan.
Short guided intake about your history and goals.
Add hair photos and blood tests if you have them.
Clear interpretation and next steps, usually within 48 hours.
Behind the three steps:
A connected system for biology, treatment, and surgical transparency.
Key factors that influence your hair — in plain language.
Androgen sensitivity and hormone balance.
Iron, vitamins and minerals that support hair.
Inflammation and follicle environment.
Pattern and progression context.
A clear snapshot and a path forward — usually within 48 hours.
Example output
Hair Risk Score
68/ 100
Stable range
Projected progression (interpretive; your report includes full context).
The Hair Risk Score and related indices (e.g. DHT Risk Index™, Follicle Stability Rating™) are derived from your biology and history. They are interpretive tools to guide strategy — not diagnostic labels. Your report includes written interpretation and next-step recommendations.
30+ years international trichology and hair restoration.
Biology-first mapping and clear strategy.
Protocols and training used worldwide.
We use evidence-based biological reasoning and a structured framework (Follicle Intelligence™) for case interpretation. We do not prescribe; we interpret and recommend. Prescriptions require your local doctor or a partnered prescriber. For clinician training and surgical audit, see our ecosystem partners (IIOHR, HairAudit).
Evidence-based resources
Begin with HLI's foundational guide to hair longevity, then explore more specific resources on postpartum shedding, male pattern hair loss, and androgen-related thinning.
Start here
Foundational Guide
Understand how hair loss works, the most common causes of thinning and shedding, what early signs matter, which tests are worth considering, and what evidence-based options may actually help.
Women's Hair Health
Understand why postpartum shedding happens, what is normal, when to investigate further, and how to support healthier regrowth.
Men's Hair Health
Learn how male pattern hair loss progresses, what early signs to look for, and which evidence-based strategies may actually help.
Hormones & Hair
Explore how androgen biology, hormone exposure, and follicular sensitivity can shape hair-loss risk in both men and women.
Clear, practical education grounded in hair and scalp science — designed to support better decisions before problems progress.
No referral required. Clear results, usually within 48 hours.
A few minutes for the questionnaire. You can add blood tests and hair photos if you have them — or upload later.
Most people get their personalised summary within 48 hours after we have your completed intake and any uploads.
Yes. We look at hormone balance, nutrients, scalp health, and pattern for all hair types and causes of loss.
