Measurement of cortisol in hair is emerging as a biomarker for chronic stress in human and nonhuman primates. Because of its external nature, hair is potentially vulnerable to a loss of cortisol from within the hair shaft due to repeated exposure to various substances such as shampoo (in humans) and water (in free-ranging monkeys). This study examined the influence of both factors on the hair cortisol levels of indoor laboratory housed rhesus monkeys. The effect of shampoo and water cannot be tested in humans because of the need to have hair that had no prior exposure to these elements. Hair was shampooed and exposed to water in vitro (i.e., after it had been gently shaved from the nape of the neck of the rhesus monkeys).
