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
