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

The study investigates the use of polydopamine (PDA) combined with a quercetin nanosystem (PDA@QLipo) to enhance the perifollicular microenvironment and promote hair regrowth in androgenetic alopecia. The materials used include dopamine hydrochloride, cholesterol, lecithin, and quercetin, among others. The synthesis of PDA and PDA@QLipo involved specific chemical processes, including mixing, stirring, and sonication. The findings suggest that this combination could potentially accelerate hair regrowth by improving the conditions around hair follicles.
