PP405 shows promise as a hair loss treatment, with 31% experiencing increased hair density in a short trial. It may complement treatments like finasteride and minoxidil, but long-term effectiveness and safety need confirmation.
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.
OP used 1mg finasteride for 4 years, then had a hair transplant, and for the past 6 months has been using 0.5mg dutasteride and 2.5mg oral minoxidil twice daily. The treatments resulted in significant hair density and thickness improvement.
PP405, a topical LDH inhibitor, has shown to stimulate hair follicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.
A treatment showed a 20% hair density increase in weeks, with nearly a third of participants experiencing significant results, while questions remain about its long-term efficacy and effectiveness across different scalp areas. There is interest in combining it with finasteride and minoxidil for potentially better outcomes.
The user is considering using P5P to reduce high prolactin levels and is questioning if oral minoxidil could be contributing to the issue. They are also debating whether to switch from oral to topical minoxidil.
PTD-DBM therapy for hair loss is being developed by Dr. Kang-Yell Choi, with human testing planned in South Korea. Some clinics in the U.S. offer PTD-DBM/valproic acid therapy, but it hasn't completed trials yet.
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.
The conversation is about gathering serum DHT data from individuals taking dutasteride to investigate its efficacy, especially in cases with unexpectedly low DHT reduction. The aim is to explore potential genetic factors affecting drug metabolism.
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.
The conversation discusses diffuse unpatterned alopecia (DUPA) and its possible causes, including sensitivity to DHT, not being androgenic alopecia, being diffuse alopecia areata, or hormonal issues. Treatments mentioned include topical melatonin, Clobetasol Propionate for alopecia areata, and the lack of results from using finasteride, dutasteride, and minoxidil.
The conversation discusses the fluctuation of testosterone levels in men under 40 and the difference between serum DHT and scalp DHT. It also mentions that DHT levels are higher on Dutasteride than on Finasteride, which is unusual.
HMI-115, a newly discovered hair loss treatment that could potentially be effective for those with diffuse thinning and telogen effluvium. It is based on prolactin receptor antagonist signaling and has already undergone Phase I trials in women, with potential commercialization by 2027.
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.
Concerns about the long-term safety of VDPHL01, an extended-release minoxidil, due to potential risks similar to Cantu syndrome, were raised, highlighting the lack of monitoring for chronic connective tissue changes. The conversation suggests that while the treatment may improve hair growth, it could lead to issues not detected in short-term 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.
The conversation discusses the effectiveness of different doses of Dutasteride (Dut) in reducing scalp DHT levels. It suggests that 1mg and 1.5mg doses would reduce scalp DHT by amounts between 51% and 79%.
The user is asking for opinions on whether their hair growth is due to Pantostin and hormone treatments. One commenter confirms regrowth and asks about the hormone treatments.
User's 2-month hair loss treatment includes Dut 0.5mg, oral min 2.5mg, Dut+PRP mesotherapy, microneedling, and other products. Dermatologist increased min dose to 5mg, expecting better results at 6-month mark.
The user has DUPA and suspects autoimmune activity as a cause. They have tried various treatments including finasteride, minoxidil, dutasteride, pyrilutamide, estrogel, hydrocortisone, and clobetasol, and are now seeking a long-term immunosuppressant.
A user has been taking finasteride for 5 months with no improvement in diffuse hair loss and suspects high levels of prolactin, cortisol, progesterone, and DHEAS, as well as iron, might be contributing to the issue. They are also taking vitamin D to address a deficiency.
A user on .5 mg of dutasteride for hair loss saw no improvement and is considering increasing to 2.5 mg but is unsure of its effectiveness. Another user mentioned that 2.5 mg reduces scalp DHT more and increases hair count more than .5 mg, but the cost and side effects should be considered.
User experienced hair loss since 16, used Fin, Minox, and Nizoral with success but stopped due to side effects. Now using Pur D'or shampoo, Rogaine foam, scalp massages, volumizing spray, and dermarolling for hair maintenance.
The user has been taking dutasteride for 8 months and finasteride before that, with normal DHT levels but high estradiol and prolactin, leading to sexual side effects. The user is disappointed with these results.
The user diagnosed with DUPA tried treatments like dutasteride, finasteride, RU58841, and minoxidil without success and is considering a hair system. They hope for a future cure, possibly with PP405, and others suggest options like scalp biopsy and SMP.
The conversation discusses the cost and insurance coverage of a comprehensive hormone and DHT blood panel for hair loss, with a focus on finasteride treatment. The user seeks a cheaper alternative to a $700 panel recommended in a video.
A user in their early 20s is concerned about minor hair thinning and is considering a hair loss regimen involving PRP sessions, mesotherapy with dutasteride injections, and low-dose finasteride. They dislike minoxidil due to its greasiness and prefer a routine that is easy to maintain.
The user experienced sexual side effects after starting finasteride and later switched to dutasteride, noticing hormonal changes. They are considering using P5P and possibly aromatase inhibitors to manage high prolactin and estradiol levels.
PP405 is progressing rapidly through trials, with mixed opinions on its potential effectiveness. Current treatments like minoxidil and finasteride are still widely discussed, with some users reporting positive results from new formulations.
