The risk factors of the WMSDs that were identifiedrnincluded, work experience [AOR: 2.5, 95%CI (1.2-5.4)], time spent in standingrnposition for long periods [AOR: 2.6, 95%CI (1.6-7)], working hours per week [AOR:rn1.5, 95%CI (1.06-2.4)], BMI[AOR: 2, 95%CI (1.1-4.1)], and thermal condition[AOR:rn1.6, 95%CI (1.0-2.4)]. Taking sufficient rest by hair dressers was one of the copingrnstrategies adopted by the hairdressers.rnConclusions and recommendation: The prevalence of work related musculoskeletalrndisorder among hair dressers was higher and the three most body parts reported werernlower back, shoulder and hand.
