“…This high frequency of occupational rhinitis symptoms has been also reported among bakers with occupational asthma [24]. Regarding LMW agents, a questionnaire-based study [25] in almost 5000 hairdressing students revealed that 18% had rhinitis symptoms. Nasal symptoms were also common among waste collectors [26] and significantly higher among healthcare and kitchen workers compared with the general population [27].…”

“…However, it is unlikely that the hairdressing industry is able to empower workers with meaningful alternative placements in all areas of either high-or low-income countries. Efforts to replace products containing multiple hazardous substances with less harmful products should have priority (Lysdal et al 2014), and a next logical step in preventing adverse health effects would be to develop safer products and to ensure their availability in Iran and other parts of the world.…”

Objective Exposures at hairdressers’ work have been reported to lead to an increased risk of several health outcomes. The present study aimed to investigate the relations between occupational exposures and respiratory symptoms and lung function among hairdressers in Iran. Methods We conducted a cross-sectional study to compare potential respiratory effects among 140 women working as hairdressers to such effects among 140 women working as office workers (administrative personnel). Both groups worked in Shiraz, Iran. Respiratory symptoms were assessed by a standard respiratory questionnaire. The questionnaire also inquired about substances used and workspace conditions, including ventilation type. Lung function levels were measured by spirometry. Results Respiratory symptoms, including cough, wheezing, shortness of breath, and chest tightness were significantly more frequent in hairdressers compared to the reference group (p < 0.05). After controlling for potential confounders, hairdressers had a prevalence ratio (PR) of 2.18 (95% CI 1.26–3.77) for cough, 9.59 (95% CI 1.004–91.73) for wheezing, 2.06 (95% CI 1.25–3.39) for shortness of breath, and 3.31 (95% CI 1.84–5.97) for chest tightness compared to the reference group. Lung function parameters (including VC, FVC, and FEV1) were significantly reduced in hairdressers (p < 0.001). Absence of air conditioning predicted greater reduction in lung function (p < 0.05) in the exposed. Decrease in FVC with normal FEV1/FVC in the exposed group suggested existence of restrictive lung function. Conclusions This study provides evidence of increased prevalence of respiratory symptoms and restrictive lung function impairment among hairdressers in Iran.

“…We identified 10 articles [5••, 27, 43-50] related to respiratory outcomes ( Table 2). Four studies assessed respiratory symptoms via questionnaires [43][44][45][46], while six additionally collected biospecimens and/or measures of lung function or inflammation [5••, 27, 47-50]. One study in New Zealand [47] reported an increased odds of self-reported chronic bronchitis symptoms among participants who had ever reported working as a hairdresser, although no associations with objective measures of lung function or chronic obstructive pulmonary disease (COPD) were observed.…”

“…One study in New Zealand [47] reported an increased odds of self-reported chronic bronchitis symptoms among participants who had ever reported working as a hairdresser, although no associations with objective measures of lung function or chronic obstructive pulmonary disease (COPD) were observed. Lysdal et al [46] reported higher prevalence of respiratory symptoms among hairdressers with adult asthma onset, as assessed by a mail-in questionnaire among 5239 Danish hairdressing school graduates. Twentyseven percent of respondents reported difficulty breathing or shortness of breath after contact with bleaching products.…”

“…OR odds ratio; 95%CI 95% confidence interval a While other outcomes were assessed in the study, data presented in the table is limited to respiratory outcomes. 27,43,[45][46][47]50], sole reliance on questionnaires to ascertain respiratory outcomes [43][44][45][46], lack of biomonitoring to ascertain exposures and related health outcomes to specific contaminants [27,43,45,47,48,50], lack of adjustment for critical confounders [44], small samples sizes [27,47,48], and potential bias arising from the healthy worker effect [27, 43-47, 49, 50]. Despite these limitations, studies generally arrived at similar conclusions.…”

Purpose of Review To review the literature published from 2014 to 2019 on hair and nail salon workers concerning exposure assessment, reproductive and respiratory endpoints, and endocrine disruption, in relation to workplace exposures. Recent Findings We identified 29 relevant peer-reviewed publications. Overall, there were insufficient studies to determine whether working in these settings is associated with reproductive health endpoints, although prior studies suggest that reproductive effects are of concern. There is consistent evidence that working in hair and nail salons may increase the risk of respiratory effects. Also, despite the fact that many hair and nail care products contain endocrine disrupting compounds, no recent studies have evaluated endocrine-related endpoints. Moreover, few studies have evaluated chemical exposures in these settings and biomonitoring studies are sparse. Summary Improved exposure assessment of chemical hazards in hair and nail salons is necessary to properly characterize occupational exposures and assess their potential health risks. Further studies on endpoints related to endocrine disruption and reproductive health outcomes among hair and nail salon workers are needed. Improved exposure and epidemiologic studies will help inform chemical exposure mitigation efforts in a vulnerable occupational population, as well as policies related to workplace and consumer product safety.
