Key Takeaways
- Androgenetic alopecia is the primary cause of hair loss in 95% of men.
- DHT levels 5 times higher in balding scalps compared to non-balding.
- Genetic predisposition accounts for 80% of male pattern baldness risk.
- Hair loss market valued at $3.5 billion annually in US.
- Average lifetime cost of hair transplants: $10,000-$15,000.
- Minoxidil users spend $500/year on treatment.
- The AR gene on X chromosome contributes 40% to male pattern baldness heritability.
- Over 200 genetic loci associated with androgenetic alopecia identified via GWAS.
- EDA2R gene variants increase baldness risk by 2.5-fold in men.
- Testosterone converts to DHT via SRD5A2, binding AR 5x stronger.
- DHT shortens anagen phase from 1000 to 300 days in follicles.
- Postmenopausal estrogen drop increases relative androgens by 30%.
- Globally, androgenetic alopecia affects about 50% of men and 40% of women by age 50.
- In the US, male pattern baldness impacts 80 million people, with 2/3 being men.
- Alopecia areata prevalence is 1 in 1,000 people worldwide.
Genetics, DHT, and deficiencies drive most hair loss, while treatments like minoxidil and finasteride help regrowth.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
