New hair loss treatments PP405 and VDPHL01 are discussed with skepticism and hope, alongside existing treatments like minoxidil and finasteride. Users express frustration over limited progress since the 1980s but remain cautiously optimistic.

A user is concerned about the impact of topical dutasteride on sperm quality and potential long-term fertility issues. They are using microneedling with a 0.025% dutasteride solution and are seeking information on whether sperm parameters return to normal after stopping the drug.

The user experienced significant hair shedding after using a dermapen at 1.5mm weekly, which they later realized was too much. They are now using a dermapen at 0.75mm weekly and are also using topical minoxidil twice daily and finasteride 1.25mg daily.

Creatine generally does not affect hair loss, but some report increased shedding due to higher DHT levels. Many manage hair loss with dutasteride, finasteride, and minoxidil.

The user is experiencing increased hair shedding and is concerned about regression despite consistent use of finasteride, minoxidil, and other treatments. The consensus is that this is likely a temporary shedding phase, and adjustments to the dermarolling frequency are suggested.

The user has been experiencing diffuse hair thinning despite using finasteride, minoxidil, dermarolling, clobetasol cream, and PRP sessions. They seek advice on additional treatments and are advised to check vitamin D, iron, and thyroid levels.

PP405 is a new hair loss treatment targeting dormant hair follicles, with ongoing trials. Some users consider stopping finasteride and minoxidil to join trials, while others doubt its effectiveness.

The user is experiencing intense hair shedding all over the scalp after applying pyrilutamide to the hairline and taking oral castor oil. They are also using topical finasteride and latanoprost, but are unsure which treatment is causing the shedding.

This post and conversation are about the molecular mechanisms triggered by microneedling, specifically its effects on inflammation, tissue remodeling, epithelial proliferation, differentiation, and collagen synthesis. The discussion highlights the potential benefits of microneedling for hair loss treatment.

The conversation is about when GT20029, a hair loss treatment, might be available on the grey market, with users discussing the challenges of compounding it and speculating it might be available after phase 2 results, similar to pyri. Specific treatments mentioned are pyri, RU58841, and GT20029.

A user reported that after experiencing hair thinning, they started using finasteride in 2024 and later began GHK-Cu peptide injections in March 2026, which they believe stopped their hair loss and made their hair feel thicker. The user shared their experience despite receiving criticism for not solely endorsing finasteride.

The user experienced increased hair shedding after switching from finasteride to dutasteride, despite lifestyle improvements and additional treatments like oral minoxidil and PRP. They are concerned about persistent shedding, changes in hormone levels, and potential chronic telogen effluvium, and are considering a scalp biopsy for further investigation.

A user experienced side effects from finasteride and switched to using GHK-Cu for hairline improvement, noticing some positive changes after three months. They used a 2mg daily dose via subcutaneous injections and reported increased hair density and baby hairs, though results were not dramatic.

Topical dutasteride, particularly at 0.05%, shows greater hair density improvement than oral finasteride over 24 weeks, though hair thickness gains are similar. Some users report side effects with topical treatments, but others find them effective for maintaining hair without significant systemic absorption.

GT20029 and pyrilutamide are both androgen antagonists but work differently; GT20029 degrades the androgen receptor, while pyrilutamide blocks DHT from binding. GT20029 is expected to have similar efficacy to CosmeRNA.

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 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 started using topical latanoprost and dutasteride, experiencing significant hair shedding and scalp itchiness, possibly due to an allergic reaction. They are considering stopping the treatment if the shedding is linked to an allergy.

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.

User shows wet hair and blow drying to prove no hair fibers used. Hair gains achieved with finasteride and minoxidil.

PP405 might make minoxidil unnecessary, but finasteride or other 5AR inhibitors may still be needed. PP405 is expected to be expensive and not available until at least 2028, with limited information on its effectiveness.

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 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.

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.

Minoxidil, dutasteride, and copper peptides are used in a tattooing method for hair regrowth, with some users noting better results compared to oral treatments. Copper peptides are considered to have minimal impact, but the method may reduce side effects.

The conversation discusses the safety study of PP405, emphasizing that early trials focus on safety rather than efficacy, and that any efficacy data from such a short study should be viewed skeptically. It also highlights that the information released is primarily for securing funding, and that meaningful efficacy results are expected in later phases.

The conversation is about the struggles of dealing with diffuse thinning at a young age and the lack of significant improvement after using treatments like finasteride and minoxidil. Some suggest additional methods like derma rolling, microneedling, and hair fibers, while others share their own experiences and encourage persistence with treatment.

PP405 is a potential hair loss treatment that may reactivate dormant hair follicles, with Phase 3 trials expected. Some users are cautious, suggesting using finasteride in the meantime, while others are skeptical about PP405's effectiveness.

PP405 is considered a potential new treatment for hair loss, compared to finasteride and minoxidil. There is skepticism about its effectiveness in humans, with anticipation for more information from an upcoming conference.

The user noticed small circular hairless spots after a buzz cut and has been using finasteride, dutasteride, and oral minoxidil for hair loss. They are experiencing continuous shedding and thinning, and it is suggested they consult a dermatologist for a scalp examination and possible biopsy to determine if it's alopecia areata or androgenetic alopecia.
