Advances in Microbial Poly(3-Hydroxybutyrate-Co-3-Hydroxyvalerate) Over the Past 5 Years: Applications in Medicine, Food, and Environment

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.

Breezula's phase 3 results are expected in July or August, with commercialization possibly in two years. There are concerns about delays and effectiveness, and the cost may be high.

The conversation discusses the delay in the PP405 Phase 2 study results, now expected by the end of 2025, and skepticism about research practices. There is also mention of optimism for Amplifica's AMP303 and a topical treatment in early testing.

PP405 shows promising results for hair density improvement, potentially outperforming Minoxidil in a shorter time. However, its public release is expected around 2029/2030, and its cost and availability remain uncertain.

Veradermics' phase 2 trial of slow-release oral minoxidil shows promising hair regrowth with minimized side effects, gaining significant attention and funding. PP405 is also noted for its potential as a side-effect-free alternative.

Probiotics like L. reuteri ATCC PTA 6475 and B. longum BB536 may improve hair growth and density by reducing inflammation and reversing DHT damage. The user is trialing these probiotics personally, ordering them from the U.S. to Canada, and plans to continue if no adverse effects occur.
