New Insight Into the Multifactorial Pathophysiology of Hair Loss: Inflammation, Stress, and Follicle Biology Take Front Stage

As our understanding of the microenvironment of the hair follicle deepens, it is becoming increasingly clear that targeting a single pathway in this complex system is not ideal. Androgens, cortisol, and corticotropin-releasing hormone, all of which are not in balance in hair loss due to internal and external stress, and gene expression of pro-inflammatory mediators all affect the hair follicle to suppress “normal” function and negatively influence hair growth.
