Inflammation and Follicle Miniaturization: What Cytokines Reveal
Uncover how inflammatory molecules shrink follicles and contribute to different forms of alopecia.
Follicle miniaturization — the progressive shrinking of hair — is a hallmark of many alopecia types. A 2024 paper in The Journal of Dermatological Science explored cytokine-driven inflammation’s role in this process.
- Pro-inflammatory cytokines (IL-6, TNF-α) suppress follicle stem cell renewal.
- Chronic inflammation reduces blood flow to the follicular papilla.
- Anti-inflammatory diets and topical treatments reduced hair density loss by ~20%.
- Targeting cytokines may slow hair loss progression.
Inflammation links multiple forms of hair loss, from autoimmune alopecia to stress-induced shedding. Mapping these molecules provides new therapeutic targets.
The study did not differentiate between sources of inflammation (e.g., diet, stress, or infection).
