Hair Straightening and Uterine Cancer Risks

During this time, 378 women were diagnosed with uterine cancer. Those who frequently (four or more times per year) used hair straightening products had a 4.05% chance of developing the disease by age 70, compared to a 1.64% risk among women who did not use them.

Formaldehyde and heavy metals (such as nickel, arsenic, and chromium) are types of carcinogens, and Johnson-Arbor revealed they have been associated with cancer development.
