RU58841, an anti-androgenic compound, showed early promise for treating alopecia but faced challenges after its patent in 1997. Despite advancing to Phase II trials, safety concerns and financial struggles led Aventis to abandon its development. Proskelia, which later merged into ProStrakan, couldn't prioritize the drug, leading to its eventual stagnation and failure to reach the market.

Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.

PP405 significantly improves hair density, outperforming finasteride, with 31% of users seeing over 20% improvement in four weeks. Concerns exist about its availability, cost, and long-term effects.

The user is considering switching from pyrilutamide to 0.025% topical finasteride due to concerns about effectiveness and past side effects from a scalp elixir. They aim to maintain hair until new treatments like breezula or GT00029 become available.

A custom-made serum based on double-blind studies for AGA, which includes natural ingredients such as rosemary oil, procyanidin B-2, saw palmetto extract, curcuma aeruginosa, pumpkin seed oil and castor oil. The user has updated their recipe to include apple poly procyanidin B-2 4% concentration and other ingredients before topping it off with Pura d'or serum.

The safety of combining alfatradiol and fluridil with finasteride as a potential treatment for male pattern baldness, which is approved in the European Union. Other treatments such as minoxidil and RU58841 were also discussed.

Hair loss treatments, including PP405, minoxidil, finasteride, and RU58841, with hopes for future solutions. Participants discuss the emotional impact of hair loss and consider alternatives like hair transplants or acceptance.

Choosing between KB and PG solutions for applying RU58841, considering factors like scalp oiliness and absorption. Some users prefer KB for being gentler, while others use PG and recommend washing hair before application for better results.

The conversation discusses concerns about RU58841 degrading when exposed to light and transferring pyri to a dark glass bottle to prevent this. The user keeps the pyri out for only two minutes before storing it in a dark place.

The user switched from oral minoxidil to topical minoxidil and added JXL-069/PP405-3HP, along with topical dutasteride, melatonin, and tretinoin. They also use low-level laser therapy (LLLT) but doubt its effectiveness.

Hair loss discussion includes treatments like Minoxidil, finasteride, and RU58841. Platelet rich plasma treatment is considered expensive but cheaper than hair transplant.

Exosomes combined with fractional picosecond laser treatment were effective in treating androgenetic alopecia and promoting repigmentation in white hair patches. The role of exosomes in hair repigmentation, particularly in conditions like poliosis, is not well-studied.

A user is considering trying Aevin hair creme, which contains ingredients like jojoba oil and saw palmetto, despite skepticism about its effectiveness compared to treatments like finasteride, minoxidil, or hair transplants. They are wary of the product's legitimacy due to the lack of reviews outside the brand's website.

The conversation is about the FDA approval of WINLEVI for acne treatment and the anticipation of Breezula, a hair loss treatment using the same active ingredient, which may indicate a positive future for Breezula's release. There is disappointment that Breezula's results are not optimal, but it is seen as progress in hair loss treatment.

Veradermics' phase 2 trial of slow-release oral minoxidil shows promising hair regrowth with minimized side effects, gaining significant attention and funding. PP405 is also noted for its potential as a side-effect-free alternative.

The conversation discusses using cyproterone acetate at 12.5 mg to manage hair loss, with concerns about its effects on testosterone and potential health issues. Other treatments mentioned include finasteride, dutasteride, minoxidil, and RU58841, with varying experiences and outcomes.

DLQ01, a prostaglandin F2α analog, shows promise for hair growth by directly stimulating PGE2/PGF receptors without needing conversion, and can be combined with minoxidil and retinoids like tretinoin for enhanced effectiveness. Minoxidil's efficacy may be reduced by COX-1 inhibitors, but using prostaglandin analogs like Latanoprost or Bimatoprost can help maintain its effectiveness.

Pelage executives' hairlines were discussed, with speculation about them using PP405 for hair regrowth. Concerns were raised about using untested drugs, with some suggesting executives might not risk using them without safety data.

Sprocketshead asks if pyrilutamide can be applied with minoxidil, and inquires about its consistency and odor. They want to know if it's more high maintenance than topical minoxidil.

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.
