Inhibition of 5α-Reductase, IL-6 Secretion, and Oxidation Process of Equisetum Debile Extract as Functional Food and Nutraceutical Ingredients

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.

Topical application of Eriodictyon angustifolium extract can prevent and reverse age-related beard graying and darken gray hair by increasing melanin production. Sterubin, a component of the extract, also promotes hair pigmentation and protects cells from DNA damage.

The user is experiencing scalp irritation from using RU58841 with a 70% ethanol and 30% propylene glycol vehicle and is considering switching to a less irritating vehicle, such as 30% ethanol with 70% squalane or emu oil. They are seeking feedback on the effectiveness and irritation levels of these alternative carriers.

Finasteride and dutasteride are discussed for hair loss, with concerns about their effects on neurosteroids and potential side effects like depression. Alternatives like topical estrogen and lifestyle changes are considered, with varying opinions on mental health and hair regrowth.

The conversation discusses the potential of Sanguisorba Officinalis Root Extract as a treatment for hair loss by inhibiting FGF-5. The user also mentions the product évolis, which is based on this extract but is only available in the US and Australia.

The solution contains minoxidil, finasteride, azelaic acid, caffeine, retinoic acid, and procapil. Users suggest minoxidil with tretinoin and a 5-alpha reductase inhibitor, while dismissing retinoic and azelaic acids as unnecessary.
