Oral PTD-DBM was discussed as a potential hair loss treatment, but it was deemed ineffective in humans despite promising results in mice. The conversation concluded that trying it without VPA might be unwise.

Female considering adding topical anti-androgen, seeks advice on RU58841 or pyrilutamid's binding affinity compared to spironolactone.

PP405 is a promising molecule that may reactivate dormant hair follicles, potentially offering a new treatment for hair loss. It is in phase 2 trials, with possible availability between 2027 and 2030.

ABS-201, a prolactin receptor blocker, shows promise in reversing hair loss and graying, with early success in macaques. Current treatments like finasteride, minoxidil, and RU58841 are still widely used, but new options like PP405 are eagerly anticipated.

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.

PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.

The conversation discusses the absorption and effectiveness of PG-free versus PG versions of RU58841, with some users believing PG improves efficacy while others see no difference. Concerns about RU58841's potential side effects on the endocrine system are also mentioned, with one user considering switching to pyrilutamide.

AH-001 is a new topical treatment designed to degrade androgen receptors, targeting the root cause of androgenetic alopecia without the side effects of oral treatments like finasteride. It has shown a strong safety profile and good local tolerability in early trials.

The conversation discusses the lack of public information on the chemical structure of PP405, a hair loss treatment, and the challenges of synthesizing it without a patent. It also explores a patent related to hydrogen-based topical formulations for reducing oxidative stress and inflammation.

PP405 is a potential new hair loss treatment that works through metabolic pathways rather than hormonal ones, with an estimated market release between late 2027 and 2029. Current alternatives to finasteride include minoxidil, pyralutamide, fluridil, and RU58841, with hair transplants also being a viable option.

PP405 shows promise for hair growth with significant results after 4 weeks, but skepticism exists due to its unavailability. Some users are hopeful for its potential, while others express concerns about side effects and market release delays.

PP405 is a potential hair loss treatment showing promise, especially for men with severe balding. Some are hopeful it will be a game-changer for those who cannot tolerate finasteride or minoxidil, despite skepticism about the outcomes.

Setipiprant and Fevipiprant are questioned for their effectiveness in hair maintenance, with skepticism due to lack of convincing results beyond vellus hair growth. The user is satisfied with Minoxidil and Finasteride but is curious about the potential of DP2 inhibitors.

A new hair loss treatment, PP405, showed promising Phase 2a results with 31% of patients experiencing over 20% hair density increase without systemic absorption, avoiding hormonal side effects. The treatment is expected to be expensive, with Phase 3 trials starting mid-2026, and there is skepticism about the data's strength.

PP405 and GT20029 are new hair loss treatments with different mechanisms from traditional options like Minoxidil and Finasteride. PP405 targets hair follicle stem cells to reactivate growth, while GT20029 works as an androgen receptor deleter, both requiring ongoing use for effectiveness.

User wants to add RCP to regimen and asks if it can be applied with topical minoxidil and/or finasteride at night.

VDPHL01 shows faster and stronger hair growth compared to standard minoxidil, with no major side effects reported. Users discuss combining it with other treatments like dutasteride and finasteride for better results, while expressing skepticism about the effectiveness of PP405.

PP405 is progressing to Phase 2b trials, with results expected in late 2025 or early 2026, and potential Phase 3 trials in 2026. Some users experienced side effects from finasteride and are hopeful for PP405 as an alternative treatment.

People are discussing the use of an untested hair loss treatment called PP405, which is not available on the grey market. Some users are trying a mimic formulation called HP3, reporting thicker hair but no new growth yet.

AMP-303 and AMP-601 are new hair loss treatments targeting dermal papilla cells, with AMP-303 showing early efficacy in transitioning vellus hairs to terminal hairs after one injection. Further clinical trials are planned, and these treatments are seen as promising due to their biologic approach and less frequent application compared to daily treatments.

PP405 is discussed as a potential adjunct therapy for hair loss, with skepticism about its effectiveness and trial results. Users mention combining it with finasteride and minoxidil for better results, while others debate the root causes of hair loss and the limitations of current treatments.

Various hair growth treatments were discussed, including microneedling, bimatoprost, setipiprant, stemoxydine, PGE2, CB-03-01, WNT Beta-Catenin upregulators, KY19382, topical estrogen, IGF-1, GH, MK-677, oral castor oil, fisetin, resveratrol, cetrizine, and lactic acid. Users shared experiences and sources for these treatments, with some expressing interest in topical solutions and others noting the lack of FDA approval or scientific evidence for certain options.

PP405 may help with hair regrowth, especially when combined with minoxidil and finasteride, but its long-term effectiveness is unclear. Phase 3 trials are expected to begin soon, with results in a few years.

The conversation questions the lack of feedback on the effectiveness of PGE2 and setipiprant for hair loss, despite their availability. The user is puzzled by the absence of reviews or results, whether positive or negative.

PP405 is a potential new hair loss treatment that might replace finasteride and minoxidil, but it is still in clinical trials and may not be available until 2028-2031. There is skepticism about its effectiveness, with only a 20% increase in hair density observed in some participants.

The conversation is about the effectiveness and production of GT20029, a drug being developed as a topical androgen receptor degrader for hair loss, and whether it can fully degrade androgen receptors or only partially. It also discusses the drug's potential unique working mechanism and synthesis by a company called Anagen.

The GT20029 tincture, a topical androgen receptor degrader, showed significant hair growth and good safety in a China Phase II trial for male androgenetic alopecia (AGA), with the 1% dose twice weekly identified as optimal. The company plans to initiate Phase III trials in China and Phase II in the U.S., and the treatment also shows promise for acne.

PP405 shows significantly better early-stage hair regrowth results compared to minoxidil and finasteride, with 31% of users experiencing over 20% density increase in 4–8 weeks. Minoxidil and finasteride show minimal or no visible regrowth in the same timeframe.

The conversation discusses the approval of Kintor Pharmaceutical's AR-PROTAC (GT20029) for clinical trials in China for acne and androgenic alopecia. One user expresses optimism about new treatments being developed and seeks clarification on how the new drug works, specifically if it temporarily degrades the AR protein to reduce DHT sensitivity in hair follicles.

PP405 is being discussed for hair regrowth, with mixed opinions on its effectiveness and legitimacy. Some users report early signs of regrowth, while others are skeptical about its authenticity and results.
