    TLDR Understanding the nanoscale structure of skin fibrosis can improve knowledge of wound healing and tissue regeneration.
    This review discusses the nanoscale structure and biophysics of cutaneous fibrosis, highlighting the role of the extracellular matrix (ECM) and fibroblast activation in wound healing. Techniques such as Raman spectroscopy, nanoindentation (NI), atomic force microscopy (AFM), and small-angle X-ray scattering (SAXS) are emphasized for their ability to characterize collagen protein expression, local ECM biomechanics, and collagen ultrastructure. These methods can enhance our understanding of the biophysical interactions within the collagen fiber network, aiding in the comprehension of fibroblast behavior and the mechanisms underlying tissue regeneration and fibrosis.

      in Research/Science  114 upvotes 3 years ago
      Natural treatments for hair loss, specifically peppermint oil and rosemary oil; how they can be used as a supplementary or alternative treatment to pharmaceuticals such as finasteride and minoxidil; and the personal experience of the user Divallo, who has seen an increase in density and thickness after using these oils for around 2.5 years. The post also touches on the potential antifungal properties of the oils and their effects on cutaneous blood flow.

      community Not sure if fin is enough, still losing lots of hair

      in Finasteride/Dutasteride  6 upvotes 1 year ago
      The user has been on finasteride for 17 months to treat hair loss, with some improvement in the crown but still experiencing significant shedding. They are considering if finasteride alone is sufficient and are hesitant to use minoxidil due to a pre-existing condition, while another person suggests trying dutasteride.
