Targeting Potential of Zinc Oxide Nanoparticles and Finasteride-Loaded Nano Lipidic Carriers-Infused Topical Gel - In Vitro and In Vivo Skin Permeation Studies

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.

Finasteride and dutasteride have potential risks, including post-finasteride syndrome, but are commonly used for hair loss. RU58841, minoxidil, and needling are suggested as alternatives, though all treatments carry risks.

Finasteride can reduce neuroactive steroids, causing side effects like depression, anxiety, and sexual dysfunction. Some users experience persistent symptoms after stopping finasteride, while others use alternative treatments like topical solutions.

Dutasteride may not effectively stop scalp hair loss and can cause thinning of facial and body hair, including eyebrows. Users suggest considering other causes like autoimmune conditions or vitamin deficiencies and exploring treatments like finasteride or minoxidil.

A user named "EgyptStar81" who has been dealing with hair loss since age 15 due to genetics, chemotherapy and finasteride/minoxidil treatment. Possible solutions such as dutasteride, oral minoxidil, hair transplants and extensions were suggested.

A 25-year-old man with hair loss from bleach damage is using oral minoxidil and considering adding Dutasteride for better regrowth and prevention. He seeks advice on Dutasteride's effectiveness and potential benefits over finasteride, and is also curious about RU58841.
