OBJECTIVES: Exposure to chemical agents in salon products, such as ammonia and formaldehyde, poses significant respiratory health risks for hairdressers. This study aimed to assess the prevalence of Diffuse Parenchymal Lung Disease Patterns (DPLD) observed in chest X-rays of hairdressers in the National Capital Region and to document their reported respiratory symptoms.
METHODS: An analytical, cross-sectional study was conducted involving 100 hairdressers who underwent plain chest X-ray examinations to identify any of the 12 recognized DPLD patterns. Participants also accomplished a self-administered questionnaire detailing their demographic information, working conditions, health histories and current respiratory symptoms.
RESULTS: Thirty nine percent of participants showed DPLD patterns on chest X-rays, primarily fine reticular opacities (69.23%) and coarse reticular opacities (25.64%). Positive associations (RR>1) were linked to over five years of work, lack of PPE, daily exposure to hair iron steam, respiratory symptoms, and salon vapor exposure of exceeding five hours daily. Symptoms reported included shortness of breath (27%) and throat irritation (15%). Logistic regression confirmed a significant link between DPLD and positive respiratory symptoms.
CONCLUSIONS: This study highlights the risk of structural lung abnormalities and respiratory symptoms among hairdressers, emphasizing the need for improved workplace safety, consistent PPE use, and routine medical screenings to reduce occupational health risks.
