The user discusses their long struggle with hair loss, considering various treatments like hair transplants, hair systems, and natural methods such as micro-needling, vitamin supplements, and a healthy lifestyle. They express concerns about side effects from drugs like finasteride and ultimately lean towards using a hair system for better appearance and confidence.

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.

User discusses a promising topical Procyanidin B2 treatment for hair loss. Users share mixed experiences and mention effective treatments like finasteride, minoxidil, and LLLT.

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.

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.

A user received a topical finasteride solution from a pharmacy, which likely dissolved finasteride tablets instead of using pure finasteride powder, resulting in sediment. The user expressed dissatisfaction, expecting pure powder, and discussed the pros and cons of DIY solutions and the use of minoxidil with finasteride.

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.

A user made a 70/30 ethanol/propylene glycol topical finasteride solution but noticed chunks at the bottom. The discussion focuses on this issue with the DIY hair loss treatment.

RU58841, a potential hair loss treatment, was not commercialized due to marketability issues and lack of long-term safety data. Concerns about its formulation and delivery methods further complicate its use.

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.

Rotenone, a natural plant extract, may promote hair growth by increasing LDH activity and blocking MPC in the scalp, but it carries risks due to its toxicity. The suggested formulation includes Barbasco extract, DMSO, propylene glycol or PEG-400, ethanol, and a carrier oil.

User experienced hair thickening with pyri but also side effects like reduced sex drive. Stopping pyri and returning to CB restored sex drive, suggesting pyri may go systemic or be incorrectly formulated.

User creates 0.1% topical finasteride solution using Alfatradiol Avixis base. Seeks help to ensure alfatradiol base dissolves finasteride.

Concerns about CosmeRNA safety mechanisms and potential side effects. Discussion includes comparisons to Fluridil and questions about nanoparticle specificity and siRNA stability.
