Frequently Asked Questions
Yes. Androgenetic alopecia (male pattern baldness) is primarily genetic. The androgen receptor gene on the X chromosome (inherited from your mother) plays a key role, but genes from both parents contribute.
FDA-approved treatments include finasteride (oral) and minoxidil (topical). Finasteride blocks DHT and can slow or reverse hair loss in ~80% of men. Early intervention is most effective.
About 25% of men begin balding by age 21. By age 35, roughly 66% show some hair loss. By age 50, about 85% of men have significantly thinner hair.
Acute stress can cause telogen effluvium (temporary shedding). Chronic stress may accelerate androgenetic alopecia. Stress-related hair loss is usually reversible once the stressor is removed.

Methodology
This calculator estimates baldness risk using a weighted point system based on family history (strongest predictor), current hair status, rate of loss, stress level, and smoking status. The Norwood-Hamilton scale classifies hair loss from NW1 (no loss) to NW7 (extensive loss). Progression rate is estimated from the risk score using epidemiological data on male pattern baldness timelines.
Male pattern baldness (androgenetic alopecia) is primarily genetic, with the androgen receptor gene on the X chromosome being a key factor. About 25% of men start balding by 21, 66% by 35, and 85% by 50. Risk factors include family history (strongest predictor), stress, and smoking. FDA-approved treatments are finasteride and minoxidil, most effective when started early.
