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.

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.

TGF-B affects hair growth, both causing stem cell division and death depending on amounts. Amplifica's treatment injects Scube3 to increase TGF-B for hair growth.

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.

Hair regrowth treatment involving 3aHSD enzyme shows 6% improvement in 18 weeks. Sulforaphane, L-Menthol, and Dexpanthenol are potential ingredients for new hair loss solution.

Corticosterone inhibits GAS6, affecting hair follicle stem-cell activity, with potential implications for stress-related hair loss. Ashwagandha and Vitamin K are suggested for reducing cortisol, but their effectiveness is debated.

The conversation is about seeking updates on the hair loss treatment RCH-01, specifically its next phase and any news from Shiseido. The user recalls someone being in contact with a researcher or company representative.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

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.

JW0061 shows superior hair growth results compared to existing treatments, with significant increases in hair follicles. The Wnt/β-catenin pathway is crucial for hair growth, and JW0061 activates this pathway effectively.

Shiseido's hair loss treatment reported only 5% regrowth, disappointing many. Users discussed other treatments like Minoxidil, finasteride, RU58841, and CB-03-01 as potential alternatives.

The discussion is about using ASCEplus HRLB exosomes for hair loss treatment, which combines 10 billion exosomes with growth factors, nutrients, biotin, and copper tripeptide. The treatment is expensive and typically administered via scalp injections, but in Europe, it's done with microneedling.

Chime Biologics and Hope Medicine are speeding up the launch of a first-in-class antibody drug, HMI-115, for endometriosis and androgenic alopecia. The treatment involves a series of subcutaneous injections, has shown promising results in phase 1, and continues to promote hair regrowth even after the treatment is stopped.

3aHSD enzyme's role in hair loss and a crowdfund for research. Goal: explore new treatments, study RU58841, and develop natural topical product.

Amplifica is testing a compound called AMP-303 for hair loss, but it's not Scube3 or osteopontin. The timing for the results from the clinical trial is unknown.

The conclusion of the conversation is that the user "Shakalakaplaka" shares their comprehensive hair loss regimen, which includes various treatments targeting different pathways such as DHT, inflammation, fibrosis, immune system, testosterone, gut problems, and scalp health. The effectiveness of the regimen is not confirmed, and some users express skepticism or request before and after pictures for credibility.

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.

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.

ABS-201 shows promise for male hair regrowth by blocking the prolactin receptor, with higher expected efficacy than current treatments. The discussion also covers dosing differences between macaques and humans for hmi115, highlighting a significant dosage disparity.

Hair loss may be linked to the TRPS1 gene and protein, not just DHT. Amplifica's AMP-303 targets mesenchymal stem cells and shows promise in treating hair loss, unlike Pelage's PP405.

Peptides like GHK-Cu, BPC-157, and TB-500 have significantly reduced hair loss, with GHK-Cu being particularly effective. The discussion also covers the high cost of these peptides and explores more affordable purchasing options.

The post and conversation are about the role of the enzyme 3alpha-hydroxysteroid reductase in hair loss and the potential of compounds like procyanidin B2 and sulforaphane to boost its activity for hair regrowth. Further research is needed to develop effective treatments based on this theory.

The user experiencing diffuse hair loss is using various treatments including RU58841, finasteride, minoxidil with tretinoin, anti-hair loss shampoo, and microneedling, and is considering adding peptides TB500, BPC157, and GHK-Cu. They have low growth hormone levels and are questioning its impact on hair loss, while another user suggests androgenic alopecia and androgens are likely the main cause of hair loss.

Hair loss treatments discussed include Minoxidil, Finasteride, and RU58841. HMI-115, a monoclonal antibody drug, is in phase 1 and 2 trials for different conditions, but its availability on the gray market is unlikely due to high production costs.

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.

HMI-115, a potential treatment for hair loss that can reverse miniaturization and make individual hairs thicker, as evidenced by data from macaques given the treatment and one subject in the phase I trial.

Cold shock therapy may promote hair growth, but cold alone is not effective. Combining treatments like minoxidil, finasteride, cold showers, spicy foods, and exercise may enhance results.

Hope Medicine's announcement of the HMI-115 Phase II clinical trial for androgenetic alopecia in China; other related trials have been conducted or are ongoing in different countries, including Australia, US, and Europe.
