March 2020 in “Aids Reviews” This review found that hair antiretroviral concentration may be associated with several factors, including hair type and genetic factors, but not with race/ethnicity or alcohol use.
April 2026 in “Frontiers in Veterinary Science” This study observed that in privately owned, intact cats, male cats exhibited significantly higher long-term hair cortisol concentrations compared to females, while environmental and behavioral factors did not significantly impact cortisol levels, suggesting individual traits may influence stress markers more than external factors.
