    TLDR Quercetin nanocrystal gel shows promise for hair regrowth in androgenetic alopecia.
    The study investigates the development of a quercetin nanocrystal gel (QT-NC gel) as a novel topical treatment for androgenetic alopecia (AGA). By enhancing the transdermal delivery of quercetin, the QT-NC gel significantly improved skin penetration and retention compared to traditional formulations. In a dihydrotestosterone-induced AGA mouse model, the gel demonstrated significant hair regrowth, reduced DHT levels, and increased hair coverage and diameter, comparable to minoxidil. The combination of quercetin and glycyrrhizic acid showed synergistic effects, suggesting QT-NC gel as a promising therapeutic strategy for AGA with potential for clinical application. Further studies are needed to explore follicular targeting mechanisms and conduct clinical trials.

      A user shared their frustration about their cousin's refusal to take their advice on using finasteride for aggressive hair loss, despite the cousin's desperation and current use of minoxidil and consideration of PRP injections. The user, who has done extensive research, suggested the cousin needs a 5ar inhibitor, but the cousin dismisses the advice because the user isn't a doctor.

      The conversation is about the lack of improvement in hair loss after using Pyrilutamide for 14 weeks, with the original poster unable to use Finasteride due to depression. Replies suggest that Pyrilutamide, like RU58841, may not work for everyone, and a more potent drug is being developed by Kintor.
