Women want the dye to be present on the hair, but not on the
scalp. Among women with other slow genes (the "CYP1A2 slow"
phenotype), exclusive permanent hair dye use was associated
with a 2.5-fold increased risk.
Large epidemiological studies show no elevated health risk for
women using hair dyes. Now, an equally important part of the
study is those women who were not at increased risk despite
using the hair dye. It state that women who used permanent
hair
dye once a month had a 25% higher rate of bladder cancer.
Women who dye their hair might be different from the average
woman in many ways. Those women have turned to at home hair
dye
kits. I heard of women going bald from over-dyeing their hair,
or braiding it. The study of 1,300 women claims that those who
started dyeing their hair before 1980 were one-third more
likely to develop NHL. The researchers did not find any larger
risk of cancer in women who started using hair dye later than
1980. The exception was women who used black hair dye for more
than 20 years. Another study found that women who dyed their
hair one to four times a year had a greater risk to develop
ovarian cancer. Women who smoke and use permanent hair dyes
have an even higher risk of cancer.
More studies might look at the risk of cancer from exposure to
hair dye at work, which the researchers excluded from this
analysis. For hematopoietic cancers, studies found a slightly
increased risk of cancer in people who had used hair dye. For
bladder cancer and breast cancer, the results indicate that
there was no effect of hair dye use on cancer risk.
Risk of salivary cancer increased three times in hair dye
users
and risk of brain and ovarian cancer almost doubled. Personal
use of hair dyes and risk of cancer: a meta-analysis. The
researchers found no strong evidence of a link between
personal
hair dye use and an increase in cancer risk. But researchers
have not been able to find a clear link between using hair dye
and cancer risk, including the risk of breast cancer.
Take-home
message. This study supports previous research that found no
link between hair dye use and increased risk for breast
cancer.
