Kim Hayes wrote for AARP that while many of us only focus on the aesthetic pleasure of having flowing shiny locks, the fact is that dull, limp strands, or hair loss, can sometimes indicate a health issue. Here are a few conditions to watch out for: Hair loss and graying
While thinning and graying hair can be a standard part of aging for both women and men, a recent study of 2,000 men in India showed that participants who had coronary artery disease were more likely to be prematurely bald or gray. The study, conducted by the European Society of Cardiology on men under 40, discovered that the 50 percent of participants with coronary artery disease were more likely to have gone prematurely gray, versus 30 percent of a healthy control group, the BBC reports. The participants in the heart condition group were also more likely (49 percent) to have male pattern baldness, compared with those in the healthy group (27 percent).
Metabolic or hormonal stress and certain medications can cause hair loss, especially if it is sudden. This condition is called Telogen effluvium, according to Medscape. In a majority of cases, new hair starts growing within six months, but longer durations of the condition also exist.
