PP405 is a potential hair loss treatment undergoing trials, with discussions on its effectiveness and comparison to existing treatments like finasteride and minoxidil. There is skepticism about its status as a cure, with hopes for future advancements in genetic treatments like CRISPR.

SCUBE3, a protein linked to hair growth in moles, was discovered over 25 years ago and is being developed by Amplifica for potential hair loss treatment. Concerns exist about SCUBE3's association with cancer, as it is a protein that promotes cell growth, which could potentially trigger cancer development if used for hair growth therapy.

The user experienced hair thinning from chromium and alpha lipoic acid supplements, which stopped after discontinuing them. Someone mentioned this could be telogen effluvium, a temporary condition.

Topical Finasteride is most effective at 0.1-0.25%, and Minoxidil at 5%. Tretinoin is optional, and additional ingredients like biotin, caffeine, and saw palmetto are recommended.

Adding caffeine to topical minoxidil is unlikely to enhance its effectiveness, with most users agreeing it has minimal impact. The main treatments discussed are minoxidil and finasteride, with some users adding other ingredients like azelaic acid and retinol.

A new hair loss treatment, PP405, is moving from phase 2A to 2B in clinical trials, sparking discussions about its potential to regrow dormant hairs and its impact on existing treatments like Minoxidil and finasteride. Some users express skepticism, while others are hopeful about its future effectiveness.

The post discusses the experiences of individuals with diffuse hair thinning using finasteride, with many reporting no improvement or worsening conditions after 6 months. Various suggestions include persisting with the treatment, checking for underlying conditions, adding minoxidil for volume, adjusting dosage, and considering other potential causes like autoimmune responses and inflammation.

The user is experiencing hair loss at the hairline and is using finasteride, but considering minoxidil due to lack of improvement. Replies suggest that minoxidil may be more effective for hairline maintenance, especially when used in combination with finasteride.

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.

Finasteride can quickly raise estradiol levels by blocking DHT, allowing testosterone to convert to estrogen. Taking finasteride for just a few days can affect blood test results.

Dutasteride effectively stops hair loss but can cause side effects like sexual dysfunction, muscle mass changes, and testicle shrinkage. Adjusting the dosage may help manage these side effects, but long-term health effects remain a concern.

The conversation discusses doubts about the effectiveness of topical finasteride for hair loss, suggesting that DHT could be produced elsewhere in the body and affect the scalp. It proposes that androgen receptor antagonists like spironolactone and clascoterone might be more effective as they could prevent this potential bypass mechanism.

Cannabis and THC may have mixed effects on hair, with some studies suggesting potential negative impacts on hair growth in isolated hair follicles, but these results are hard to apply to living humans. Treatments like minoxidil and finasteride are commonly used for hair loss, and the effects of cannabis might be neutral or vary based on individual factors.

The conversation discusses skepticism about Breezula, a hair loss treatment, with the consensus that it's not a miracle cure but a maintenance drug that may work well with finasteride. Some users report side effects from finasteride, like sexual dysfunction, while hoping for better results from Breezula or RU58841 without such side effects.

Some users report encouraging results with laser caps for hair loss, while others see no improvement. Treatments mentioned include low-level laser therapy, Minoxidil, and finasteride.

The conversation is about the potential availability of GT20029 on the black market and whether users would try it. Participants advise waiting for phase 3 trial results to ensure safety and efficacy.

A user is considering starting finasteride for hair thinning but is concerned about side effects like low libido and gynecomastia. They plan to consult a dermatologist and are advised to test DHT, testosterone, and estradiol levels.

A user is experiencing increased hair shedding after using a homemade topical finasteride mixture with stemoxydine for six weeks. They are concerned about whether the low dose could cause shedding so early.

User discusses hair loss treatments, including fluridil, minoxidil, tretinoin, melatonin, stemoxydine, ketoconazole, and piroctone olamine. They suggest that shedding healthy terminal hairs may be bad, while shedding weaker hairs could indicate a beneficial treatment effect.

Scientists found hidden stem cells that might reactivate hair growth. The discussion includes treatments like Minoxidil, finasteride, and RU58841.

PP405's phase 2a trial results were presented, focusing on safety and pharmacokinetics, with a future meeting planned to share the full dataset. The trial includes a randomized controlled portion and an open-label extension, with no indication of phase 2B completion.

The conversation discusses experimenting with microneedling for hair loss, specifically addressing non-responsiveness and the use of topical treatments like dutasteride, minoxidil, and tretinoin. The user seeks advice on effective frequency and depth combinations for better results.

Hair thickness can fluctuate while on finasteride, possibly due to product overuse or other factors like health or hormones. The user experienced a significant thinning in November 2025 but noticed improvement since then.

Lighting and camera angles can greatly affect the appearance of hair thickness in photos. Consistent conditions are crucial for tracking progress, and treatments like Minoxidil and finasteride can show results in about 6-8 months.

A new topical treatment, PP405, shows promising results for hair regrowth, potentially outperforming existing treatments like finasteride and minoxidil. However, it may still need to be combined with DHT blockers for optimal results, and its long-term effectiveness remains uncertain.

The user experienced increased shedding and an itchy scalp after switching from Ascend to Aurobindo finasteride. They are considering switching to dutasteride and are concerned about elevated estrogen levels and the effectiveness of adding minoxidil later.

The conversation is about the anticipated results of Pelage's Phase 2a clinical trial for their topical hair loss treatment, PP405. Users speculate on when the results will be available, noting that delays might indicate less successful outcomes.

Low-dose oral minoxidil shows mixed results, with some users experiencing hair regrowth and others seeing no significant change. Finasteride is also commonly used, often in combination with minoxidil, and is generally considered effective with a low rate of side effects.

The user experienced side effects like heart palpitations, chest tightness, and fatigue from using 5% minoxidil foam once daily. They are considering switching to a 2% concentration due to lingering symptoms like lightheadedness and brain fog.
