New Study Links Hair Dye to Breast Cancer. Here's What You Need to Know

A new study reported claims that of the thousands of ingredients that go into hair products used to dye and straighten our hair, some might play a role in kick-starting breast cancer in women already at risk. Among nearly 47,000 women with sisters diagnosed with breast cancer, researchers from NIEHS and the University of North Carolina identified a significant increase in incidences of the disease among those who dyed or straightened their hair frequently.
