Did you mean Perifollicular Hyperpigmentation?

GlossaryPerifollicular Hyperpigmentation

darkening of skin around hair follicles due to inflammation

Perifollicular hyperpigmentation refers to the darkening of the skin around hair follicles. This condition often occurs due to inflammation or irritation, such as from acne, folliculitis, or certain hair removal methods, leading to an increased production of melanin in the affected areas.

community Polydopamine Synergizes with Quercetin Nanosystem to Reshape the Perifollicular Microenvironment for Accelerating Hair Regrowth in Androgenetic Alopecia.

in Research/Science 11 upvotes 1 year ago

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.
