We collected and analysed the data from the patient group, diagnosed through typical clinical findings of PCD and the control group, which comprised age\/sex\u2010matched patients who visited the participating hospitals with pre\u2010existing skin diseases other than current allergic disease or PCD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Melasma and photosensitivity were significantly more common in the control group, and a history of contact dermatitis was more common in the PCD group. There were significantly more Fitzpatrick skin type V participants in the PCD group than in the control group. There was no significant difference in sunscreen use between the groups. Using dermatologic medical history, Fitzpatrick skin type and sunscreen use as covariates, we showed that hair dye use carried a higher PCD risk (odds ratio [OR] before adjustment: 2.06, confidence interval [CI]: 1.60\u20132.65; OR after adjustment: 2.74, CI: 1.88\u20134.00). Moreover, henna users had a higher risk of PCD (OR before adjustment: 5.51, CI: 4.07\u20137.47; OR after adjustment: 7.02, CI: 4.59\u201310.74), indicating a significant increase in the risk of PCD with henna dye use.
