Epidemiological evidence on hair dyes and the risk of cancer in humans.
Epidemiological data on occupational exposure and personal use of hair dyes was reviewed with specific focus on bladder cancer and lymphoid neoplasms.
At least seven cohort and 11 case-control studies included data on occupational exposure to hair dyes by hairdressers, barbers and beauticians, and their subsequent bladder cancer risk.
The relative risk (RR) estimate was 1.4 (183 observed vs 129 expected) for cohort studies, and in several case control studies the RRs were somewhat above unity.
These results are compatible with some moderate association between past professional exposure to hair dyes and subsequent bladder cancer risk, but also with errors and biases in observational epidemiological studies, particularly since allowance for smoking was lacking or inadequate in most studies.
An open question is whether current occupational exposure to modern hair dyes is still related to some excess bladder cancer risk.
Five case-control studies included information on personal use of hair dyes and bladder cancer risk.
There was no evidence of any association.
