November 2004 in “Brain Behavior and Immunity” This study found that stress increases the number of peptidergic nerve fibers and mast cell activity in mouse skin, suggesting a significant neuro-immune interaction under stress.
April 2026 in “Comprehensive Psychoneuroendocrinology” This study found a partial positive association between adulthood stressor exposure and hair cortisol levels, but noted inconsistent results across two studies, reflecting variability seen in previous research.
In this study, a Monte Carlo-generated synthetic cohort analysis found that higher simulated cannabis exposure was linked to increased self-assessed hair loss severity and reduced follicular density, suggesting potential connections worth exploring in further clinical research.
In this simulation study, higher cannabis exposure was associated with increased hair shedding severity and reduced follicular density, with greater effects observed in female-assigned profiles, but these associations are based on modeled data and not clinical observations.
This simulation study found that higher cannabis exposure in a virtual population was associated with increased hair shedding severity and reduced follicular density, but these results are based on modeled data and cannot establish causal relationships.
