A new study looks to clarify the theorized connection between hair dye and cancer.
The study did not find a link between using hair dye and an increased risk of most types of cancer in women.
It did however find a possible relationship between hair dye and certain forms of breast cancer.
The study also showed possible links between the dyes and ovarian and some types of skin cancer.
That study has kept track of women's health and lifestyle habits since 1976.
More than 120,000 women between the ages of 30 to 55 were initially enrolled.
