5α-Reductases in Human Physiology: An Unfolding Story

Finasteride can impact neurosteroids, potentially causing depression and other side effects in some users. Despite these concerns, many continue using it for hair loss, with some switching to topical applications to mitigate side effects.

The conversation concludes that finasteride, a 5α-Reductase inhibitor used for hair loss, does not impair cognition either short-term or long-term. It suggests "brain fog" is not caused by the medication.

The DHT itch is linked to hair loss and persists despite finasteride use; switching to dutasteride helped alleviate the itch and promoted regrowth. Some users suggest seborrheic dermatitis as a cause and recommend treatments like medicated shampoos, vitamin D, and minoxidil.

The conversation discusses the link between seborrheic dermatitis, acne, and male pattern baldness, suggesting that DHT may cause both skin conditions and hair loss. Treatments mentioned include RU58841, finasteride, dutasteride, minoxidil, Nizoral shampoo, and other topical anti-androgens.

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.

Rosemary Oil may inhibit the activity of 5α-Reductase, potentially promoting hair growth. Specific treatments discussed include Minoxidil, Finasteride, and RU58841.
