Inhibition of 5α-Reductase Activity in SZ95 Sebocytes and HaCaT Keratinocytes In Vitro

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

GHK-Cu helped control Seborrheic Dermatitis and reduced scalp irritation, with no immediate change in hair fall or growth. Users reported reduced flakes and healthier skin using GHK-Cu topically.

Hair follicles cannot be desensitized to DHT like allergies; treatments focus on reducing DHT levels or blocking its effects using methods like finasteride, GT20029, or PROTACs. Topical treatments like ceterizine and BPA application are also mentioned.

ABS-201 shows promise for male hair regrowth by blocking the prolactin receptor, with higher expected efficacy than current treatments. The discussion also covers dosing differences between macaques and humans for hmi115, highlighting a significant dosage disparity.

Finasteride, Minoxidil, Bioneer CosmeRNA, Technoderma, Kintor, Hope, Breezula, and Follicum treatments showed increases in hair count, with Technoderma showing the highest increase at 24.3 hairs/cm². Amplifica has not yet published results.

Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.
