Q: Do my hair and nails really reveal anything about the state of my overall health, as so many women's magazines claim?
A: To some degree, this is TRUE -- especially with your nails. And while "you can't look at someone and determine their general health or how well they're aging by their hair and nails," says Richard Scher, MD, a professor of dermatology at Columbia University College of Physicians and Surgeons in New York City, your coif and manicure can betray a number of health concerns.
For instance, certain changes in the nails can point to particular diseases. Some types of heart disease can turn the nails bright red, while fully white nails may suggest liver disease.
"If the nails become yellow, it may indicate diabetes or lung disorders, such as sinusitis. If they lose their nice pink color and become very pale, it could be a sign of anemia," says Scher.
Nails offer more clues for the health detective, but some hair disorders can point to disease, Scher says. A sudden, rapid onset of brittle hair (rather than lifelong split ends) or hair loss could point to broader health problems.
