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.

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.

A user is seeking advice on creating a homemade finasteride foam similar to over-the-counter Minoxidil foam, due to issues with glycerin and propylene glycol in their current solutions. They are considering using a mixture of ethanol/alcohol and water for the foam.

The user experiences irritation from alcohols in minoxidil and is considering alternatives like trichosol mixed with polyethylene glycol or DMSO. They seek advice on the best nonirritating option.

PP405 is suspected to be a scam, with users doubting its legitimacy and effectiveness. Many recommend using proven treatments like finasteride and minoxidil.

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.

PP405 is being discussed as a potential new approach to hair loss by targeting follicle stem cells, suggesting a different mechanism from existing treatments like finasteride and minoxidil. However, there is skepticism about whether it will lead to meaningful long-term outcomes or follow the pattern of previous treatments that showed promise but lacked consistent results.

OP asked if a product from Amazon is sufficient to dilute finasteride. A user advised against using propylene glycol alone, suggesting a pre-made solution instead.

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.

Diluting finasteride in a Hims spray can be done using ethanol or propylene glycol to maintain the desired concentration without increasing minoxidil levels. This approach ensures the finasteride concentration is reduced to 0.025% without affecting the minoxidil strength.

Everychem's solution, similar to PP405, has mixed results for hair regrowth, with some users reporting improvements and others seeing no change or worsening hair loss. Users are sharing experiences and updates to determine its effectiveness.

A new hair loss treatment, pp405, may regrow hair better than finasteride and minoxidil, with potential availability by 2028. However, there is skepticism about its effectiveness and commercialization timeline.

The conversation discusses a patent filed by Shiseido for cloning Dermal Papilla (DP) cells to treat hair loss. The method involves using viral vectors to maintain the cells' growth-inducing properties, differing from Replicel's approach with Dermal Sheath Cup (DSC) cells.

PP405's effectiveness in increasing hair density is questioned due to a small sample size, despite investment from Google Ventures. Users express skepticism and suggest waiting for more conclusive results.

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.

Koshine KX-826 has different versions, and the green version uses a plant-based carrier that may be less irritating for those sensitive to propylene glycol. Users report irritation with some versions of KX-826.

The conversation is about making topical finasteride using ethanol. The user is advised to use non-denatured or food-grade ethanol, as denatured ethanol may be harmful with prolonged skin exposure.

A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.

The user is seeking an alternative solvent for pyrilutamide due to skin irritation from ethanol and propylene glycol. They experienced similar issues with topical minoxidil.

PP405 shows some hair growth after 4 weeks, but results are debated and expectations should be tempered. Some users compare it to minoxidil or finasteride, questioning its effectiveness and commercialization timeline.

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.

The conversation discusses creating a DIY topical finasteride solution for someone allergic to propylene glycol, with suggestions to use glycerin or a glycerol-based vehicle instead. The user also mentions using foam minoxidil.

RU58841 powder is mixed with a 70% ethanol and 30% propylene glycol solution, with some users seeking PG-free alternatives. Minoxidil is also mentioned as a treatment option.

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.

The conversation discusses adjusting the isopropyl alcohol, propylene glycol, and water ratios in a topical finasteride solution for better scalp comfort and less dandruff. The user considers using 20ml IPA, 25ml PG, and 15ml water in a 60ml bottle, moving away from mixing finasteride with topical minoxidil.

Kintor plans to release pyrilutamide foam and a plant-based Koshine by year-end, with GT20029 progressing in their pipeline. Users are pleased about the absence of propylene glycol (PG) in the new products.

The conversation discusses using Rogain foam as a solvent for topical finasteride due to an allergy to propylene glycol. The foam's ingredients, including alcohol SD 40B, are considered suitable for dissolving finasteride for easier application without skin irritation.

PP405 is a new hair loss treatment advancing quickly in trials, generating excitement and skepticism about its effectiveness and marketing claims. Some see it as a potential alternative to minoxidil and finasteride, but concerns about long-term effects and the need for DHT blockers persist.

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.

PP405 is a potential hair loss treatment that may activate dormant hair follicles, but there are concerns about its effectiveness, cost, and side effects. Users discuss treatments like minoxidil, finasteride, and RU58841, expressing skepticism about PP405's long-term success and accessibility.
