KX-826 is undergoing Phase III trials in China as a potential treatment for male pattern baldness, with some users considering it as an alternative or addition to finasteride and dutasteride. Opinions on its effectiveness vary, with some users reporting positive results and others finding it expensive and ineffective.

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.

PP405 is a new hair loss treatment showing early promise with a 20% hair density increase, but skepticism exists due to past failures of similar treatments like Pyrilutamide, RU58841, and Bimatoprost. Users debate its potential effectiveness, with some hopeful due to Google's involvement, while others urge caution without more evidence.

There is no new information on pp405, with data collection expected to finish by the end of 2025. Users are discussing the timeline for data analysis and completion of Pelage Pharmaceuticals' phase 2 study.

A user created a tracker for hair loss treatments in clinical development, including compounds like Dermaliq, RU58841, and Pyrilutamide. The tracker updates with new information and allows filtering by conditions like androgenetic alopecia (AGA) and alopecia areata (AA).

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.

The conversation discusses the delay in bringing FAK inhibitors and Stanford's hydrogel to market for hair transplants, with a preference for FAK inhibitors over Verteporfin due to their superior potential in preventing scarring. The user expresses frustration over the slow progress and hopes for faster development by companies like FAKnostics.

The conversation discusses a community called PHG, which focuses on experimental hair loss treatments and scientific approaches to hair regrowth. It mentions treatments like Minoxidil, finasteride, and RU58841, and highlights interest in new treatments like Setipripant, Histogen, and Replicel.

PP405 is a potential new hair loss treatment that might replace finasteride and minoxidil, but it is still in clinical trials and may not be available until 2028-2031. There is skepticism about its effectiveness, with only a 20% increase in hair density observed in some participants.

A user is interested in Absci's AI-driven antibody platform, ABS-201, for treating androgenetic alopecia, which shows promising preclinical results and potential for hair regrowth and pigmentation restoration. However, concerns are raised about the drug's development timeline and its advantages compared to existing treatments.

PP405 is advancing to Phase 2b trials, showing promise from Phase 2a. It may be available in 3-6 years, with trials using a topical gel.

Ritlecitinib and PP405 show promise for hair regrowth. Diagnosing the cause of hair loss is crucial before treatment.

PP405 shows promise in hair loss treatment, but stem cell therapy using adipose-derived stem cells and ATP also successfully reversed androgenetic alopecia in mice. Stem cell therapy is costly, and some doubt the effectiveness of PP405 based on press releases.

People are discussing the potential of a new hair loss treatment, pp405, and its approval timeline, comparing it to existing treatments like Minoxidil and finasteride. There is skepticism about its effectiveness and concerns about the time it will take for approval and availability, especially in Europe.
