PP405 is a potential hair loss treatment that inhibits mitochondrial pyruvate carriers, increasing lactate dehydrogenase activity and stimulating hair follicle stem cells. In a phase 1 trial, 31% of participants showed over 20% hair density increase with PP405 treatment.

PP405 shows promise for hair regrowth by manipulating stem cell characteristics and lactate dehydrogenase, with Phase 2a trials pending. Google Ventures' $15M investment suggests confidence, but results and market availability remain uncertain.

High DHEA levels may contribute to hair loss by increasing DHT in hair follicles, potentially explaining why finasteride is ineffective for some. Treatments like high-dose dutasteride and RU58841 are suggested, but the underlying cause, such as adrenal issues, should be investigated.

The conversation discusses hair loss treatments, specifically mentioning Minoxidil, finasteride, RU58841, and TB-500 Thymosin Beta-4. It critiques the credibility of biohacking claims.

Pelage Pharmaceuticals announced positive Phase 2a trial results for PP405 in hair loss therapy. The conversation discusses the delay in publishing full results and the need for further trials and approvals.

2-Deoxy-D-Ribose is discussed as a potential hair loss treatment, but skepticism exists due to lack of human testing. The original poster uses a combination of topical Minoxidil, oral Finasteride, topical RU58841, and other treatments, reporting some hair regrowth but not significant results.

Hair follicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.

A user applied the 8T3 product for hair loss, targeting LPP and AGA, and plans to update on its effectiveness. The product uses a saline buffered phosphate vehicle, suitable for those intolerant to ethanolic vehicles.

Setipiprant and Fevipiprant are questioned for their effectiveness in hair maintenance, with skepticism due to lack of convincing results beyond vellus hair growth. The user is satisfied with Minoxidil and Finasteride but is curious about the potential of DP2 inhibitors.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

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 potential hair loss treatments focusing on stimulating IGF-1 at the follicle level using growth-factor cocktails and engineered peptides, such as Acetyl Tetrapeptide-3, Copper Tripeptide-1, Oligopeptide-20, Thymosin-β4, and Palmitoyl Tetrapeptide-7. It suggests that device-assisted delivery methods like microneedling may enhance effectiveness.

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

Osteopontin, a protein involved in hair growth on moles, may help with hair loss. However, it is also linked to Alzheimer's, cancer, and bone development, so caution is advised.

The post and conversation are about skepticism towards a new hair loss treatment containing 2-deoxy-D-ribose, copper peptides, and exosomes, with concerns about the legitimacy of the product and its website. The treatment's effectiveness and authenticity are questioned due to lack of testing and transparency.

The conversation discusses hair loss treatments, focusing on a new slow-release oral minoxidil compared to topical minoxidil and finasteride. The results show that twice-daily dosing of the new treatment is slightly more effective than once-daily, but concerns about cost, side effects, and the accuracy of reported results remain.

2 Deoxy D Ribose may promote hair growth and aid wound healing, potentially enhancing microneedling effects. Users discuss its combination with microneedling for better hair growth results.

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.

A 16-year-old is experiencing hair loss and is using minoxidil, finasteride, and plans to add RU58841, while considering other treatments like MK-677 and microneedling. Concerns are raised about the potential impact of these treatments on puberty and development.

The conversation discusses HMI 115, a new hair loss treatment with promising results, showing a significant increase in hair density after two months. Some users are skeptical, while others are hopeful for its release and potential affordability.

RT1640, a combination of cyclosporin A, minoxidil, and RT175, is discussed as a potential treatment for hair regrowth and repigmentation. The unique formulation aims to enhance hair follicle growth and restore hair pigment without the negative side effects of immunosuppressants.

A user is exploring VEGF gene therapy to enhance hair transplant results, considering measuring hair shaft diameter and growth rate. Suggestions include using phototrichograms and possibly adding PRP, though its effectiveness is uncertain.

The conversation is about the use of peptide therapies for hair loss, specifically GHK-CU, ZN-Thymulin, and PTD-DBM. The user is seeking feedback on the effectiveness of these treatments from those who have tried them.

A compound called MTP3 from the Monoterpene family was found to be safe and highly effective at treating hair loss by inhibiting the FGF5 gene, but its identity is undisclosed for commercial reasons. No specific treatments like Minoxidil, finasteride, or RU58841 were discussed.

ET-02 showed significant hair growth in five weeks, outperforming minoxidil, with a non-hormonal mechanism that avoids side effects of treatments like finasteride. A phase 2 trial is planned to further assess ET-02's efficacy and safety.

The post discusses the potential of upregulating aromatase to treat hair loss, suggesting that increasing CCL2 levels through Vitamin D or microneedling might help. The user questions why microneedling doesn't work for everyone, especially those with advanced hair loss.

RU-58642 is a powerful anti-androgen that was not developed further, possibly due to safety concerns or financial reasons. RU58841 is a topical alternative, but it is less effective than finasteride and dutasteride, and its long-term effects are not well-studied.

Rhamnose may promote hair growth and pigmentation, suggesting it as a potential hair loss treatment. The conversation discusses its potential alongside known treatments like Minoxidil, finasteride, and RU58841.

GHK-Cu is a potent inhibitor of the type 1 5-alpha reductase enzyme in hair follicles, which may reduce hair loss without the side effects associated with type 2 5-alpha reductase inhibitors. The user previously experienced side effects with 5-alpha reductase inhibitors and is considering GHK-Cu as an alternative.

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.
