PP405, a potential hair loss treatment, is facing delays in releasing Phase 2 results, causing frustration among users who compare it to past failed treatments. Despite skepticism, some remain hopeful about PP405's future, while others discuss alternative treatments like Clascoterone and its expected market release.

PP405 is a potential hair loss treatment that inhibits mitochondrial pyruvate carriers, increasing lactate dehydrogenase activity and stimulating hair follicle stem cells. In a phase 1 trial, 31% of participants showed over 20% hair density increase with PP405 treatment.

The conversation is about using pyrilutamide and RU58841 as topical solutions to prevent hair loss. Pyrilutamide is considered safer but less potent than RU58841, which some users find effective despite potential side effects like heart palpitations.

Pelage Pharmaceutical raised $120 million to continue research on PP405, a promising hair loss treatment that showed a 20% increase in hair density in 31% of men during a Phase 2a trial. The treatment was well-tolerated, with no systemic absorption, and Phase 3 trials are planned for 2026.

The efficacy of degrading the androgen receptor through dermal application in DP cells, a delivery system for topical drugs that involves dissolving microneedles, and rosemary oil as an alternative anti-androgen.

PP405 shows initial promise for treating androgenetic alopecia, with safety confirmed in early trials, but skepticism remains due to limited data. Further trials are needed to determine its true efficacy and potential market impact.

Pyrilutamide is a selective AR antagonist with a high binding affinity, making it effective in competing with DHT for androgen receptors. The 1% concentration is more effective than the 0.5%, but the latter may suffice for mild hair loss; the drug is considered a good option for those avoiding 5AR blockers due to side effects.

The user experienced anxiety and side effects from topical finasteride and is considering switching to saw palmetto. Another user reported no improvement with saw palmetto and experienced liver issues.

The user seeks alternatives to Propylene Glycol (PG) for delivering topical finasteride due to scalp irritation. They consider using Propanediol 1,3 and ask for other suggestions.

PP405 is a new drug in Phase 2 trials for hair loss, generating cautious optimism among users. Some users are currently using finasteride and experiencing side effects, while others are skeptical about unapproved products being sold.

A user is interested in creating a hair growth serum using oleic acid, palmitoleic acid, and anhydrous ethanol, and seeks advice on sourcing these ingredients. Another user plans to mix these with minoxidil, which already contains ethanol, and mentions using RU58841.

Pelage Pharmaceuticals announced positive Phase 2a trial results for PP405 in hair loss therapy. The conversation discusses the delay in publishing full results and the need for further trials and approvals.

The conversation discusses the delay in the PP405 Phase 2 study results, now expected by the end of 2025, and skepticism about research practices. There is also mention of optimism for Amplifica's AMP303 and a topical treatment in early testing.

Piroctone olamine may be more effective and gentler than ketoconazole for dandruff and itchiness. Users report better results with piroctone olamine, but it is less available in the US.

The user tried pyrilutamide for hair loss and noticed reduced scalp itch and improved skin but stopped due to mild heart sensations. They plan to update after consistent use, noting improved sleep when applied at night.

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.

Hmi115, a prolactin receptor blocker, showed promise for hair growth, but results from Phase 2 trials have not been published. ABS-201, an AI-based analog, is expected to begin trials in December 2025, while commercialization of treatments like PP-405 is anticipated around 2027.

Oleic acid and ethanol are being considered for hair regrowth, with some users planning to self-experiment. There is skepticism about their effectiveness, and ongoing use of treatments like finasteride and minoxidil is mentioned.

User considers trying Pyrilutamide for hair loss and itch relief. Another user shares positive experience with Pyrilutamide, no side effects.

PP405 shows promise in hair loss treatment, but stem cell therapy using adipose-derived stem cells and ATP also successfully reversed androgenetic alopecia in mice. Stem cell therapy is costly, and some doubt the effectiveness of PP405 based on press releases.

P-1075 is a more potent hair growth agent than Minoxidil, but it poses significant heart risks, making it unsafe for use. Despite promising results in macaques, concerns about its cardiotoxicity in rats have halted its development.

Topical finasteride in a liposomal formulation reduces systemic absorption compared to ethanol solutions. The user is seeking sources for such products, noting that popular options like morr-f are not liposomal.

Users discuss using pyrilutamide for hair loss, seeking alternatives to 5AR inhibitors. They mention using minoxidil, ketoconazole shampoo, and RU58841.

Pelage is moving to Phase III clinical trials for PP405, a hair loss treatment, with results to be presented at a medical meeting. Users express skepticism and hope, comparing it to existing treatments like Minoxidil and finasteride, while discussing the potential for new hair growth in previously bald areas.

The user is considering topical Saw Palmetto or Pumpkin Seed Oil due to sensitivity to finasteride and cost issues. They also use dermastamping for Minoxidil absorption and seek advice on timing to avoid systemic absorption.

Creating a liposomal gel with Pyrilutamide for hair loss to reduce systemic effects, similar to Xyon's gel. The discussion includes concerns about ingredient sourcing and the benefits of targeted topical treatments.

Saw palmetto, a 5-alpha reductase inhibitor, caused unexpected side effects like breast changes and altered semen consistency, which resolved after stopping its use. Concerns about similar side effects with finasteride or dutasteride were expressed, and another user reported low libido and depression from saw palmetto.

PP405 is a new hair loss treatment showing early promise with a 20% hair density increase, but skepticism exists due to past failures of similar treatments like Pyrilutamide, RU58841, and Bimatoprost. Users debate its potential effectiveness, with some hopeful due to Google's involvement, while others urge caution without more evidence.
