This study investigated the microscopic changes in hair among 154 Iranian women who used hair coloring, waving, or ironing compared to those who did not. The participants were divided into four groups: controls, dyed-hair, waved-hair, and ironed-hair. The study found that abnormal hair findings were significantly more frequent in the dyed (53.1%), waved (45.7%), and ironed (54.3%) groups compared to the control group (17.1%). Specific abnormalities included trichorrhexis, kinking, pseudo pili-annulati, trichonodosis, tracheoschises, and trichoptilosis, with varying prevalence across the groups. The results indicated that these cosmetic practices could induce hair abnormalities.
