MedicalResearch: What are the main findings of the study?
Answer: Our main focus was to study hairdressers’ exposure to carcinogenic aromatic amines. We found that the concentrations of the carcinogenic compound o-toluidine in blood increased with the number of treatments per week of light color permanent hair dyeing and hair waving treatments. Another aromatic amine, m- toluidine (assessed as not classifiable as carcinogenic to humans owing to a lack of data) in blood, increased with the number of treatments per week of light color hair dyeing and all other hair dyeing.
MedicalResearch: Were any of the findings unexpected?
Answer: We did not expect that the concentrations of o-toluidine to increase with the number of treatments per week of hair waving.
MedicalResearch: What recommendations do you have for future research as a result of this study?
Answer: We will continue measuring aromatic amines in hair dye products and hair waving products for the same aromatic amines that were measured in hairdressers’ blood, to further confirm our results.
