Dicer- and Bulge Stem Cell-Dependent MicroRNAs During Induced Anagen Hair Follicle Development

    TLDR MicroRNAs are important for hair growth regulation, with Dicer being crucial and Tarbp2 less significant.
    The study investigated the role of Dicer and bulge stem cell-dependent microRNAs in hair follicle development during the anagen phase. It found that Dicer, essential for microRNA processing, was crucial for the proper function and maintenance of hair follicle stem cells, with its absence leading to impaired hair growth and follicle development. Tarbp2 was not essential for anagen development. The research highlighted the importance of Dicer-dependent microRNA biogenesis in post-natal hair follicle growth and suggested that targeting microRNA pathways could be a potential therapeutic strategy for hair loss conditions. The study provided insights into the molecular mechanisms governing hair growth and the potential for developing new treatments for alopecia.

      The user forgot their minoxidil and finasteride while traveling in Indonesia and is concerned about hair loss. They are advised that a 6-week break might cause some shedding but not drastic changes, and it's safer to wait for friends to bring the medication due to strict drug laws.

      community New molecule PP405 vs exercise

      in Research/Science  36 upvotes 1 month ago
      PP405 targets hair follicle stem cells differently than exercise-induced lactate, suggesting exercise alone may not replicate its benefits. Minoxidil and finasteride are recommended alongside exercise for hair regrowth, with additional suggestions like spicy food and infrared exposure.
