TLDR Stress can worsen skin and hair conditions by affecting the skin's immune response and hormone levels.
The document from 2006 reviews the connection between the brain and skin, particularly how stress affects the skin's immune and neuroendocrine systems, potentially exacerbating skin diseases and conditions like alopecia areata and chronic dermatitis. It explains that the skin has its own local stress response system, producing stress hormones and mediators such as CRH, cortisol, and catecholamines, which can lead to neurogenic inflammation and impaired hair growth. The paper also discusses a study using a murine model that showed chronic psychological stress could inhibit hair growth through mechanisms involving NGF, SP, and mast cells. The findings underscore the importance of further research into the brain-skin axis to develop treatments for stress-related skin and hair disorders.
