Frequent use of hair-straightening products may raise uterine cancer risk, study says

Researchers find uterine cancer risk more than two and a half times higher for women who used straightening products

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% 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%," the study leader, Alexandra White of the US National Institute of Environmental Health Safety (NIEHS), said in a statement.
