    TLDR Enzyme presence in hair sheath cells decreases over time, affecting forensic analysis.
    The study investigated polymorphic enzyme systems in human hair sheath cells using starch gel electrophoresis. It identified several enzymes, including Phospho-glucomutase, Esterase D, Glyoxalase, and others, in fresh hair sheath cells. Over time, the detectability of these enzymes decreased, with only a few remaining detectable in older sheath cells. Acid phosphatase and Adenosine deaminase activities were observed, but reliable typing was not feasible, and Peptidase A activity was absent. This research contributed to understanding enzyme presence and stability in hair sheath cells, which could have implications for forensic science.

      community Creatine is the opposite of minoxidil !

      in Research/Science  321 upvotes 2 months ago
      Creatine may counteract minoxidil's hair growth effects by closing potassium ATP channels, potentially leading to hair loss in predisposed individuals. Despite anecdotal reports, there is no conclusive evidence linking creatine to hair loss.

      community Dutasteride Literally Saves Your Hair

      in Finasteride/Dutasteride  101 upvotes 1 year ago
      Dutasteride significantly reduces scalp DHT levels and can save hair, though shedding is part of the process. Some users report success with dutasteride, while others struggle despite using it along with finasteride and oral minoxidil.

      community Why does it seem everyone favors finasteride over dutasteride?

      in Female  62 upvotes 1 year ago
      The conversation discusses preferences for hair loss treatments, specifically finasteride over dutasteride. Users share personal experiences, cost considerations, FDA approval status, and potential side effects, with some switching between treatments to find what works best for them.

      community My Theory Of Androgenic Alopecia

      in Research/Science  17 upvotes 1 month ago
      Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

      community How to reduce scalp DHT as much as possible?

      in Finasteride/Dutasteride  16 upvotes 2 months ago
      The conversation discusses reducing scalp DHT to prevent hair loss, with a focus on using dutasteride, finasteride, and other treatments like RU58841 and minoxidil. It highlights the challenges of managing hair loss while on high testosterone levels, suggesting that dutasteride may be more effective than finasteride in such cases.
