Knowledge and Attitude Among Lebanese Women Toward Hazardous Chemicals Used in Nail Cosmetics.

Middle Eastern women seek frequently for self-adornment. Harmful effects of chemicals used in nail care services have involved women worldwide. This study was performed to determine Lebanese women's knowledge and attitudes toward adverse effects of compounds used in nail cosmetics. A national cross-sectional study was carried out using an online questionnaire and targeting women in Lebanon. Data was collected on sociodemographic characteristics, nail cosmetics' application, preventive measures, perceived knowledge and self-reported side effects associated with nail cosmetic's use. A total cumulative knowledge score was calculated to categorize consumer knowledge. A total of 573 women completed the survey. Young women with a high school education or beyond were overrepresented. Most of the participants preferred applying classic manicure and removers on a weekly basis. Over 82% had poor/fair knowledge about health hazards associated with chemical compounds used in nail cosmetics with their levels of education acting as a key factor. Skin and neurological symptoms were the more frequently self-reported symptoms. Interestingly, the use of a nail hardener was linked to a higher prevalence of headache, nausea, allergy, skin irritation, itching and burn. The prevalence of the three later symptoms was higher among gel users. Moreover, few participants read nail cosmetics' labels or questioned their safety. Although nail cosmetics' application was common among Lebanese women, there is poor knowledge regarding their harmful effects. Based on these findings, it is warranted to launch health awareness campaigns and introduce a cosmetovigilance system to ensure the safety of the consumer products.
