    TLDR Hair and wool have complex microscopic structures with microfibrils and varying cystine content.
    The study by G. E. Rogers uses electron microscopy to explore the fine structural organization of a-keratins in hair and wool, identifying microfibrils as fundamental units within a sulfur-rich matrix. It highlights the effectiveness of OsO4 staining in enhancing visibility and notes structural differences in various hair and wool types, correlating microfibril clarity with cystine content. Merino wool shows distinct orthocortex and paracortex regions, with the paracortex having higher cystine content, affecting dye penetration. Human hair lacks bilateral structure but contains both microfibrillar packing types. The research provides detailed insights into the complex microscopic structure and composition of hair and wool fibers.

      Procapil is marketed as a natural hair loss treatment but lacks strong evidence and is industry-biased. Minoxidil and Finasteride are the only FDA-approved treatments for androgenetic alopecia.

      community Verteporfin and Microneedling

      in Treatments 1 year ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.

      Rotenone, a natural plant extract, may promote hair growth by increasing LDH activity and blocking MPC in the scalp, but it carries risks due to its toxicity. The suggested formulation includes Barbasco extract, DMSO, propylene glycol or PEG-400, ethanol, and a carrier oil.
