    TLDR Recombinant keratin K31 makes damaged hair thicker, stronger, and straighter.
    The study investigated the effects of recombinant keratin K31 on human hair health and reshaping, finding significant improvements in hair strength, elasticity, and appearance. Recombinant keratin K31, expressed in E. coli and purified, increased hair diameter by up to 49%, doubled mechanical strength, and straightened curly hair after a single treatment. The protein's similarity to native keratin K31 allowed it to integrate into the hair structure, filling gaps and enhancing elasticity and strength, making it a promising ingredient for hair care products aimed at repairing and improving hair health.

      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 1 year ago
      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.

      A serum containing Centella asiatica extracellular vesicles, IGF-1, FGF-7, and caffeine significantly improved hair thickness, density, length, and reduced hair loss after 56 days. The conversation also discusses how treatments like finasteride, minoxidil, and ketoconazole address different aspects of hair loss by reducing DHT, improving blood flow, and lowering inflammation.
