The authors declare that there are no conflicts of interest. Table S1 qPCR primer sequences and associated GenBank accession numbers. qPCR, quantitative real-time polymerase chain reaction Table S2. Reference controls and hair dye ingredients with skin sensitization potential. HaCaT keratinocytes were exposed to each chemical for 24 hours and cytotoxicity analysis was conducted using the MTT assay to obtain the CV80 values. CV80, cell viability ≥80%; MTT, 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors.
