Hereditary hair loss affects roughly half of Caucasian men by age 50. The condition's prevalence, however, varies significantly across different populations and decades of life.
Key Takeaways
- Approximately 50% of Caucasian men have noticeable hair loss by age 50.
- The androgen receptor gene on X chromosome contributes 79% heritability to baldness.
- Dihydrotestosterone (DHT) sensitivity due to AR gene CAG repeats <20 in 60% balding men.
- Male pattern baldness linked to 32% higher heart disease risk.
- Finasteride reduces DHT by 70% leading to 65% hair count increase after 2 years.
Most men keep balding gradually, so early monitoring can help you choose effective options sooner.
