Did you mean Perifollicular?

Glossary Perifollicular

area surrounding hair follicle

Perifollicular refers to the area surrounding a hair follicle. In medical and dermatological contexts, this term is often used to describe conditions or observations, such as inflammation or fibrosis, that occur around the hair follicles. For example, perifollicular inflammation is a common feature in certain types of hair loss, like alopecia areata, where the immune system attacks the hair follicles.

community Perifollicular Fibrosis and its role in androgenetic alopecia. Is Aminexil/Kopexil a must for anyone with AGA?

5 upvotes 4 years ago

Aminexil/Kopexil may help reduce hair loss by addressing perifollicular fibrosis in androgenetic alopecia, but it lacks the extensive clinical backing of finasteride and minoxidil. Some users find it effective, but availability and cost are issues, especially in the US where it's not FDA-approved.

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

11 upvotes 2 years 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.
