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.

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

PP405 is moving to late-stage trials, showing potential for hair regrowth, with 31% of male patients experiencing a 20% increase in hair density. Veradermics is developing an oral minoxidil version, and there is interest in combining treatments for better results.

Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.

Pelage Pharmaceuticals' PP405 aims to treat hair loss by reactivating dormant hair follicle stem cells, showing promising results in early trials. The company plans to present their findings at the American Academy of Dermatology Annual Meeting in 2026.

DUPA is considered more treatable than FAPD, as FAPD involves scarring that prevents hair regrowth. The user has started treatment with oral dutasteride and minoxidil, hoping for better results than previous treatments.

The conversation discusses the potential benefits of adding Vitamin B6 (P-5-P) to topical hair loss treatments like RU58841, finasteride, or minoxidil. The user suggests that Vitamin B6 might enhance these treatments by naturally lowering scalp prolactin.

A 28 year old using a hair loss prevention protocol to restore thinning hair, which includes finasteride, dutasteride, minoxidil, stemoxydine, alopecin, nizoral shampoo and microneedling; the user is now adding pyrilutamide solution to the regimen with the hope of improving their results. RU58841 was also ordered but not yet used.

The conversation discusses the delay in the release of a new hair loss treatment, Pyrilutamide, and speculates on potential safety concerns as a reason for the delay. It also mentions GT20029 as another future treatment option, with a release at least five years away, and touches on the avoidance of research chemicals due to uncertainty about their authenticity.

VDPHL-01 is essentially a slow-release oral minoxidil, which is already known to work for hair growth. The formulation includes other ingredients like Medrogestone, Valproic acid, Setipiprant, and Cetirizine, but their effectiveness and necessity are questioned.

PP405 is a promising new treatment for hair loss. It performs three actions in one, potentially offering a cure.

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.

The user started balding at 16/17 and tried various treatments including minoxidil, finasteride, and dutasteride with little success. They recently started applying diclofenac gel to their bald areas and noticed some hair regrowth, attributing this to diclofenac's ability to lower prolactin levels and its anti-inflammatory effects.

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 user is experiencing diffuse androgenic alopecia and is trying various treatments, including 5mg finasteride, loniten, and Formula 82D, which contains dutasteride, a steroid, and tretinoin. They report potential regrowth with Formula 82D, despite previous treatments being ineffective.

New treatments for AGA are emerging, including pyrilutumide, gt0029, scube3, kx-826, and pp405. Verteporfin is mentioned as a promising option.

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.

P5P supplementation helped reverse finasteride side effects, particularly by lowering prolactin levels and restoring sensitivity. The user experienced significant improvement within a day and full recovery in a few days.

The conversation discusses hair loss treatments, mentioning minoxidil, finasteride, RU58841, VDPHL, GT20029, and follicle cloning as potential solutions. It also reveals that the discussion about PP405 was an April Fool's joke.

TDM-105795 showed better efficacy and safety in trials for hair loss, with a higher hair count improvement compared to GT20029 and HMI 115, but it's not as widely discussed. The user is questioning why this is the case.

Extended-release oral minoxidil (VDPHL01) shows promising results for hair growth with improved safety, achieving significant hair count increases and minimal side effects compared to placebo. The treatment is designed to maintain effective concentrations while reducing side effects, making it a safer option for those who cannot tolerate standard minoxidil.

DLQ01, a prostaglandin F2α analog, shows promise for hair growth by directly stimulating PGE2/PGF receptors without needing conversion, and can be combined with minoxidil and retinoids like tretinoin for enhanced effectiveness. Minoxidil's efficacy may be reduced by COX-1 inhibitors, but using prostaglandin analogs like Latanoprost or Bimatoprost can help maintain its effectiveness.

The conversation is about a user's hair loss treatment regimen, which includes Dutasteride, oral Minoxidil, topical Dutasteride, Minoxidil sulfate, antioxidants, and various supplements. The user is also using a derma stamp and has paused Tretinoin due to a TCA peel recovery.

A user was prescribed betamethasone dipropionate spray for a receding hairline, which caused skin peeling and depigmentation. They stopped using it and are considering alternatives like BPC-157/TB-500 for healing.

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.

VDPHL01 shows faster and stronger hair growth compared to standard minoxidil, with no major side effects reported. Users discuss combining it with other treatments like dutasteride and finasteride for better results, while expressing skepticism about the effectiveness of PP405.

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.

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.

A human trial of verteporfin, a drug that can inhibit wound healing by scarring and promote regeneration of original tissue and hair follicles to provide an unlimited source for hair transplants; people discussed the potential of this drug and how it could be rolled out in mainstream with more doctors getting on board.

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.
