An assessment grounded in dermatological literature

Novalinya relies on the reference classifications published by the dermatology community and on the current understanding of the pathophysiology of androgenetic alopecia.

Pathophysiology

Androgenetic alopecia results from increased sensitivity of hair follicles to dihydrotestosterone (DHT), a testosterone metabolite produced by the 5α-reductase enzyme. This sensitivity is largely determined by polymorphisms of the androgen receptor (AR) gene, located on the Xq11-q12 chromosome region4. Over successive hair cycles, sensitive follicles undergo progressive miniaturization: shortened anagen phase, thinner hair shaft, lower overall density. The process is gradual and largely stabilizable when identified early.

Reference classifications

  • Hamilton-Norwood scale — first described by Hamilton (1951)5 and refined by Norwood (1975)6, it is the standard classification of male androgenetic alopecia (stages I to VII).
  • Ludwig scale — published by Ludwig in 19777, it describes in three stages the diffuse thinning pattern typically seen in women, with usual preservation of the frontal hairline.
  • 6-zone grid — frontal line, temples (left/right), vertex, mid-scalp and occipital: a standard clinical partitioning used to objectify the topography of hair loss and monitor its evolution.
Novalinya applies these classifications to the photos and questionnaire you provide. The result is a structured assessment — not a medical diagnosis. Only a dermatologist can establish a formal diagnosis, prescribe treatment, or identify a non-androgenetic cause (deficiency, thyroid condition, telogen effluvium, alopecia areata, etc.).
Frequently asked questions

Everything you need to know

No. Novalinya is an information tool based on artificial intelligence, not a medical device. Our assessment helps you structure your situation and arrive prepared at a consultation, but it never replaces the opinion of a dermatologist or general practitioner.
Your photos are encrypted in transit (HTTPS/TLS 1.3) and stored on secure servers in the European Union. They are never shared, never used for advertising, and are automatically deleted after analysis. See our privacy policy.
Novalinya is not a diagnostic tool and does not claim any clinical-grade accuracy. Our engine applies the Norwood-Hamilton and Ludwig classifications to the photos and answers you provide: the result is a structured assessment, useful for understanding your situation and preparing a consultation, but not a medical diagnosis. Output quality depends heavily on photo framing and lighting.
The complete analysis with score, classification and express action plan is free. An optional in-depth report at 9.99 € (one-time payment) unlocks the personalized routine, detailed OTC recommendations, medical guidance and 6-month projection.
We never prescribe. In the full report, we clearly separate OTC recommendations (over-the-counter, that you can implement on your own) and medical guidance (treatments that require a consultation). For any question about a specific treatment, we always refer you to a pharmacist or physician.
Yes — that’s precisely the goal. Your report is exportable as a printable PDF, structured to be read by a healthcare professional in under 3 minutes. Many users bring it to their consultation to save time and get a more precise opinion.
Yes. Our engine uses two scales: Norwood-Hamilton for men, Ludwig for women. The zones analyzed and the recommendations adapt automatically to the profile indicated in the questionnaire.
The questionnaire takes about 90 seconds. The AI analysis runs in under 2 minutes, and your report is displayed immediately on screen. A link to your report is also sent by email so you can come back to it later.
