Male pattern baldness isn't just about genetics - it's a complex interplay of hormones, genetics, and environmental factors:

The DHT Connection Dihydrotestosterone (DHT) is the primary culprit: - Converts from testosterone via 5-alpha reductase - Binds to hair follicle receptors - Gradually shrinks hair follicles

Genetic Factors - Multiple genes influence hair loss susceptibility - Inherited from both parents, not just mother's side - Determines sensitivity to DHT

The Hair Growth Cycle - Anagen (growth): 2-6 years - Catagen (transition): 2-3 weeks - Telogen (rest): 2-3 months

Environmental Triggers - Stress and cortisol levels - Nutritional deficiencies - Smoking and poor circulation - Certain medications

Understanding these mechanisms helps explain why early intervention is so effective.
