Regularly sporting lipstick and dying your hair may increase a woman’s risk of developing lupus, according to preliminary new research, but only if the woman already has a higher risk."It’s a little early to tell everybody that lipstick is dangerous,” says researcher Jun Wang, PhD, an assistant professor of medicine at Tufts New England Medical Center in Boston. “Lupus is not common, and a lot of people use lipstick, so not everyone who uses lipstick is at risk of lupus, but maybe a select group of people who have a genetic disposition to lupus will further increase their risk when they use lipstick,” she tells WebMD."People with a family history of lupus may need to be more cautious when dying their hair or using lipstick,” she says. “While hormones have been [implicated], [these findings] may be an explanation of the gender differences in this disease because so far no one knows what is responsible for the fact that women have a ninefold higher rate than men,” she says.Researchers presented the findings at the annual meeting of the American College of Rheumatology in San Diego.
