Hair dying, hair smoothening and straightening products are hazardous chemicals that affect human health and are frequently used in beauty salons. So, this study aimed to evaluate the genotoxic risk among the studied hairdressers, to estimate the level of p-phenylenediamine (p-PDA) in urine and to assess the degree of adherence of the studied hair- dressers to occupational safety measures at work. A comparative cross sectional study was carried out on 40 hairdressers working in beauty salons in Zagazig city, Egypt and 40 administrative staff at faculty of medicine as a control group. The results of the study revealed a significant increase in mean concentration of urinary p-PDA as well as significant increase in DNA damage assessed by Comet assay in lymphocytes among studied hairdressers than among their controls. Also, there was a statistically significant decrease in adherence to most of the occupational safety precaution measures that should be followed by the studied hairdressers. The significant risk factors of high Comet total mean score among the studied hairdressers were occupational use of hair straightening ≥8 times/week, use of hair dyes at work ≥15 times/week, length of service ≥13 years, negligence of wearing gloves during work, use of bleaching agents ≥12/week and negligence of hand wash after handling chemicals. So, it was concluded that the hairdressers are occupationally exposed to the risk of genotoxic hazards from chemicals frequently used in their work. The lack of commitment to occupational safety measures at beauty salons like wearing gloves during work and hand washing increases the risk of genotoxicity.展开更多

Skin protection is a very important factor for the prevention of occupational skin disorders. Therefore, we evaluated a hand cream that was specially formulated for highly stressed skin with regard to its capability to reduce dry, rough, and scaly skin. The objective of this study was to conduct a controlled use test of a barrier repair cream containing pseudo-ceramide and demonstrate its efficacy for hairdressers with dry, sensitive hands and/or occupational skin disorders. A total of 30 hairdressers (29 females and 1 male, aged 20 - 67) participated in the study. All subjects suffered from dry hands. Subjects applied the test cream on their hands for 28 days (four weeks). For each subject, the skin surface topography of the hands was measured by the Surface Evaluation of Living Skin (SELS) system at day 14 (week 2) and day 28 (week 4). Dryness, scaling, cracking, redness, and itchiness were evaluated and graded by experts at week 2 and week 4, and then compared to baselines. All 30 subjects completed the study. A comparison of the changes from baseline to endpoint revealed a statistically significant reduction in skin roughness, scaling, and volume measured according to SELS. These data were confirmed by photographic documentation. The results were further supported by the expert evaluation. For the symptoms dryness and scaling, improvement could be observed in almost all regions of the hands. In addition, according to subjective assessments of overall hand skin condition and the hand cream, subjects reported clear improvement over time (p value below 0.001) and good efficacy of the product. In this study, the test hand cream showed excellent skin compatibility. Therefore, the hand cream may be effective for hairdressers with dry, sensitive hands and/or occupational skin disorders.展开更多
