Hair Care Disasters: Caution with Relaxers and Dye (cont.)

In another study, published in the October 5, 1994, issue of the Journal of the National Cancer Institute, researchers from Brigham and Women's Hospital in Boston followed 99,000 women and found no greater risk of cancers of the blood or lymph systems among women who had ever used permanent hair dyes.

Then in 1998, scientists at the University of California at San Francisco questioned 2,544 people about their use of hair-color products. After integrating the results of this study with those of animal and other epidemiologic studies, they concluded that there was little convincing evidence linking non-Hodgkin's lymphoma with normal use of hair-color products in humans. The study was published in the December 1998 issue of the American Journal of Public Health.

FDA continues to follow research in this field.
