Something’s up with this coif. Graying hair on men, an Egyptian cardiologist warns, appears linked to increased risk for coronary artery disease. A study of 545 men, whose hair was graded on a 5-point scale indicating how gray or white it was, checked heart health with coronary angiography. Researchers found that subjects half-gray or more were likely to be at greater risk of heart disease, regardless of age. The Cairo University team says more research could confirm the link — and assess similar risks in women.
