Snippet from the article:
Men going thin on top may be more likely to have heart problems than their friends with a full head of hair, according to researchers in Japan.
Their study of nearly 37,000 people, published in the online journal BMJ Open, said balding men were 32% more likely to have coronary heart disease.
However, the researchers said the risks were less than for smoking or obesity. The British Heart Foundation said men should focus on their waistline, not their hairline.
Read the rest — Male baldness ‘indicates heart risk’
This paper was actually based on meta-analysis of more than 850 existing observational studies, and it found that vertex balding (not frontal hairline balding) lead to an increased heart disease risk.
Whether there is anything to it, I couldn’t say… but coincidentally (or not), I had someone ask me just last week if having a hair transplant into his crown would reduce his risk for coronary disease.
