High levels of circulating stress hormones, which may be elevated by psychological or physical stress, have been shown to impair the function of our skin barrier known as the epidermal permeability barrier,[1] leading to dryness and irritation. More specifically, the hormone cortisol is secreted by hair follicles in response to high levels of stress [2] and may promote an immune response, increased sebum production, and irritation of the scalp and hair follicles — exacerbating the condition of dandruff.[3] Dandruff has also been linked to emotional disorders such as depression, suggesting a role for psychosocial stress in this phenomenon.[4]
