I laughed at that excerpt posted that 70% of women who dye their hair had an increased risk of ovarian cancer because all they did to come up with that was ask how many women out of 189 CANCER patients dyed their hair? Back in 1993...
How on Earth can asking women if they dye their hair or not show an increase in getting ovarian cancer?
It doesn't!
How many times have we all heard that practically everything was going to cause cancer? Only to have another study come out disproving the prior report?
This is just another bunch of hogwash we (people who aren't scientists) are being fed.

May 24, 2005 -- New findings may soothe fears of a possible link between hair dye and cancer.possible link between hair dye and cancer. Researchers say that there is no strong evidence of a clear increase in cancer risk among personal hair dye users.
Bahi Takkouche, MD, PhD, and colleagues analyzed 79 studies from 11 countries, focusing only on personal use of hair dye, not occupational exposure. "Our results indicate that, globally, there is no effect of personal hair dye use on the risk of breast and bladder cancer," they write.
Their findings are reported in the May 25 issue of The Journal of the American Medical Association.
'Borderline Effect' for Blood-Related Cancers
The researchers found a "borderline effect" linking use of hair dye and blood-related cancers,"borderline effect" linking use of hair dye and blood-related cancers, such as leukemia and multiple myeloma, but "the evidence of a causal effect is too weak to represent a major public health concern." They add that this effect, as well as two studies showing a borderline increase in the risk of brain tumors and ovarian cancer, warrant further investigation.

There were also small risk increases seen in brain and ovarian cancer, but this association is also suspect.
"The results concerning brain and ovarian cancers are based on minimal sample sizes (only two studies in each case), [so] they are not as reliable as the results of the rest of the cancers we studied," Takkouche said. "Besides, they are rare cancers, and the increase in the risk, even if it exists, would be of limited interest from the public health point of view."
I think all these "studies" are done just so these institutes can justify spending so much money. They always come up with something "new" that conradicts someone else...I think they just like to try and prove they're right and have something to argue about...
Dr Kennedy said, "Of course, this question came to public awareness wit the death of Jacqueline Onassis Kennedy in 1994 from non-Hodgkins lymphoma. Jackie has been a long time user of dark brown hair dye.
Rather than give an opinion, which would be relatively worthless, let me reproduce a review of the matter from Mindspring.com and then try to put it all in perspective.
A report published in the February 2, 1994 issue of the Journal of the National Cancer Institute, showed that women who use permanent hair dyes do not have an overall increased risk of dying from cancer. However, women who used black hair dye for more than 20 years had a slightly increased risk of dying from non-Hodgkin's lymphoma and multiple myeloma. Less than 1 percent of women in this study reported that they had used permanent black hair dye for more than 20 years."
So he just took excerpts from prior reports....
None of what I saw stated that any scientific testing had been done to prove a link to dying hair and ovarian cancer. A simple study (asking women questions) was all they seemed to have based their conclusions on.
