What is the Origin of Scalp Inflammation?

The clinical recognition of inflammation's role in hair loss has evolved from the field of dermatology and trichology, moving beyond simple fungal or bacterial infections to include complex immune and hormonal mechanisms. The understanding that conditions like androgenetic alopecia involve a chronic inflammatory component around the upper follicle gained prominence in the late 20th century, expanding the therapeutic target beyond mere androgen blockade.

What is the Mechanism of Scalp Inflammation?

The inflammatory mechanism directly impacts the hair follicle's ability to cycle normally by disrupting the delicate signaling between the dermal papilla and the keratinocytes. Inflammatory mediators, such as TNF-alpha and interleukins, can trigger the hair follicle to prematurely enter the catagen (transition) phase, shortening the vital anagen (growth) phase. In hormonally sensitive areas, androgens like dihydrotestosterone (DHT) are known to initiate a perifollicular inflammatory response, which accelerates the miniaturization process and ultimately leads to permanent hair loss.

Scalp Inflammation

Meaning

Scalp Inflammation is a chronic or acute immunological response occurring in the skin and surrounding structures of the scalp, characterized by the local release of pro-inflammatory cytokines and immune cell infiltration. This pathological state is a significant, often overlooked, contributor to hair cycle disruption, follicular miniaturization, and various forms of alopecia. Even low-grade, subclinical inflammation, known as microinflammation, can progressively damage the hair follicle unit.
