Benign prostate enlargement and scalp hair loss are quite common among middle-aged males. The problems are known to come from the same origin, dihydrotestosterone (DHT). Scientists in Australia found that men with bald spots at the top of their heads were 1.5 times more likely to have prostate cancer than those without bald spots. The association was particularly strong for men who were diagnosed with high-grade prostate cancer at 60–69 years of age. In contrast, there was no link between a receding front hairline and cancer.
