Prevalence of Dermatological Disorders Among Hairdressers in Ibadan, Oyo State

Occupational skin diseases represent an underrecognized health burden among informal sector workers in Nigeria, particularly those in the beauty and personal care industry. This study assessed the prevalence and risk factors of dermatological disorders among hairdressers operating in Ibadan, Oyo State, South West Nigeria. A cross-sectional survey was conducted among 175 hairdressers across five local government areas in Ibadan metropolis. Data collection involved a structured questionnaire, skin examination using standardized diagnostic criteria, and a checklist on occupational exposure to chemical agents. Findings showed that 63.4 percent of respondents had at least one identifiable dermatological condition, with contact dermatitis (46.3%), nail dystrophy (28.6%), and eczema (19.4%) being the most common diagnoses. Frequent exposure to hair bleaching agents, relaxers, and dyes without glove use was significantly associated with skin disorders (p less than 0.05). Majority (78.3%) reported never receiving occupational health education related to chemical safety. Knowledge of the hazardous properties of commonly used products was inadequate among 84.6 percent of participants. These findings highlight the urgent need for targeted chemical safety training, mandatory personal protective equipment provision, and stricter regulation of hazardous cosmetic substances in Nigerian hair salons. The Oyo State Ministry of Health and relevant trade associations should collaborate to develop protective guidelines for beauty industry workers.
