Hair-straightening products may significantly increase the risk of developing uterine cancer among those who use them frequently, a large study published on Monday suggests.
“We estimated that 1.64 percent of women who never used hair straighteners would go on to develop uterine cancer by the age of 70, but for frequent users, that risk goes up to 4.05 percent,” study leader Alexandra White of the U.S. National Institute of Environmental Health Safety (NIEHS) said in a statement.
