A user is advocating for Phase 3 trials of the hair loss treatment PP405 to be conducted in Germany, citing benefits like a diverse patient base and faster access for European patients. Despite skepticism about the petition's influence, the user believes it can demonstrate significant interest and potentially influence strategic decisions.

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.

The conversation discusses using P5P (Vitamin B6) supplements to reduce elevated Prolactin levels and concerns about its potential effect on increasing DHT levels. The user is not currently using finasteride or any anti-androgens.

PP405 targets hair follicle stem cells differently than exercise-induced lactate, suggesting exercise alone may not replicate its benefits. Minoxidil and finasteride are recommended alongside exercise for hair regrowth, with additional suggestions like spicy food and infrared exposure.

The conversation is about the use of peptide therapies for hair loss, specifically GHK-CU, ZN-Thymulin, and PTD-DBM. The user is seeking feedback on the effectiveness of these treatments from those who have tried them.

PP405 is discussed as a potential alternative to finasteride, but its effectiveness and market availability are uncertain. Users share experiences with finasteride, minoxidil, and topical treatments, noting side effects and application techniques.

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.

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 conversation discusses using a multimodal approach to treat androgenic alopecia, including substances like gamma-linolenic acid, DHA, sulforaphane, melatonin, cetirizine, astaxanthin, fisetin, apigenin, curcumin, limonene, genistein, and berberine. Users also mention using ketoconazole, minoxidil, and low-level laser therapy (LLLT) as part of their hair loss treatment regimens.

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.

Federal funding cuts have delayed PP405 research, affecting hair loss treatment progress, though clinical trials will continue. The discussion highlights PP405's potential compared to minoxidil and finasteride and stresses the importance of government-funded research.

PP405 is seen as a potential breakthrough for converting vellus hairs to terminal hairs, with users expressing both hope and skepticism. It is compared to treatments like minoxidil and finasteride, with discussions on side effects and marketing concerns.

A woman with AGA is using spironolactone, dutasteride, finasteride, oral minoxidil, bicalutamide, and anti-androgenic birth control but still experiences worsening hair loss. Steroid shots temporarily stop her hair shedding, leading her to question her biopsy results.

People are discussing the anticipated release of PP405 phase 2a results, expected by the end of March, with some skepticism about its effectiveness. There is cautious optimism due to past experiences with similar treatments like Breezula, despite concerns about the lack of presentation at the AAD 2026 conference.

Pelage plans to conduct two Phase 3 trials for PP405, a new hair loss treatment, which may take about a year to complete. Users discuss various hair loss treatments, including pyrilutamide, minoxidil, finasteride, and clascoterone, with some expressing impatience over the lengthy trial process compared to faster drug approvals like the COVID vaccine.

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.

PP405 is criticized for overhyped claims and cherry-picked data, with doubts about its effectiveness compared to minoxidil and finasteride. Many users express skepticism, emphasizing the need for more comprehensive trial results.

Hair loss treatments Cosmerna, RU, and Pyri discussed. Cosmerna inhibits androgen receptors, but not 100%, so RU/Pyri can be used synergistically.

Setipiprant trial for hair loss failed, showing no difference between placebo and treatment. Discussion also noted placebo users reporting side effects.

The phase 3 trial results for Pyrilutamide showed no significant difference from the control treatment in increasing hair count, leading to the company halting its development. Users discussed their disappointment and skepticism about hair loss treatments, with some mentioning other treatments like Minoxidil, Finasteride, and RU58841.

A 57-year-old man with male pattern hair loss and insulin resistance experienced hair regrowth and weight loss after using tirzepatide, without other hair treatments. Dysregulated glucose metabolism is linked to hair loss, with tirzepatide potentially improving hair density by normalizing insulin resistance.

GT20029 is a topical treatment that degrades androgen receptors to prevent hair thinning and loss, potentially offering fewer side effects than systemic treatments like finasteride. Concerns include its impact on hair texture and potential systemic effects, with market availability speculated in 3 to 5 years.

The conversation discusses the potential effectiveness and future results of the hair loss treatment pp405, with questions about its impact on different hair loss stages and areas. There is anticipation for phase 3 trial results to provide more data, and hope that pp405 could enhance hair transplant outcomes.

Using DIM and Calcium D-Glucarate to reduce finasteride side effects. Discussion includes dosage, brand, and product effectiveness.

Alfatradiol is used by some for hair loss, often alongside treatments like finasteride, RU58841, and minoxidil, but its effectiveness is unclear. Some users report no significant improvement, while others note reduced sebum production but experience side effects like gallbladder pain.

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.
