Androgenetic Alopecia & Follicular Miniaturization Optimal Biomarker & Diagnostic Fact Matrix
| Metric | Verified Benchmark | Source |
|---|---|---|
| ICD-10-CM Diagnostic Classification | L64.9 | WHO / CMS ICD-10-CM Clinical Modification |
| Biomarker: Serum Dihydrotestosterone (DHT) | 12 – 35 ng/dL (on 5-ARI) | DotMD Preventive Optimal Target Range |
| Biomarker: Ferritin | 70 – 150 ng/mL | DotMD Preventive Optimal Target Range |
| Biomarker: 25-Hydroxy Vitamin D | 45 – 70 ng/mL | DotMD Preventive Optimal Target Range |
Pathophysiology & Clinical Presentation
Type II 5-alpha-reductase converts testosterone into high-affinity DHT within dermal papilla cells, shortening the anagen growth phase, prolonging kenogen latency, and inducing perifollicular micro-inflammation.
Hallmark Clinical Signs & Biomarker Triggers
- Bitemporal recession or diffuse crown/part-width thinning
- Increased telogen hair shedding during washing
- Progressive shaft diameter heterogeneity on trichoscopy
