    Did you mean Poisson's ratio?
    GlossaryPoisson's ratio

    measure of material's perpendicular deformation to applied force

    Poisson's ratio is a measure of how much a material deforms in directions perpendicular to the direction of applied force. When you stretch a rubber band, for example, it not only gets longer but also gets thinner. Poisson's ratio quantifies this thinning effect. For most materials, this ratio is between 0 and 0.5, where a value of 0.5 means the material volume remains constant during deformation.

      community Bloodwork reports just came in

      in Update  23 upvotes 2 years ago
      A 21-year-old male suffering from male pattern baldness is using topical finasteride and minoxidil, and oral minoxidil. His bloodwork shows normal DHT levels and slightly high testosterone, leading to discussions about the role of DHT sensitivity in hair loss, the potential impact of finasteride on his DHT levels, and the suggestion to proceed with oral finasteride due to his high testosterone.

      community Why don’t people just just DUT instead of FIN?

      in Finasteride/Dutasteride  48 upvotes 2 years ago
      The conversation discusses the use of dutasteride (DUT) versus finasteride (FIN) for hair loss treatment, with some users preferring DUT for its effectiveness while others choose FIN due to its approval status, better long-term data, and lower risk of side effects. Users share personal experiences with both medications, including side effects and effectiveness.

      community Why do people say you will have an extremely high chance of maintenance if you are on Dutasteride, if 0.5 mg only removes 50% of scalp dht

      in Finasteride/Dutasteride  30 upvotes 1 year ago
      Dutasteride and finasteride are effective for many in reducing hair loss by lowering DHT levels, though results vary based on individual sensitivity and genetics. Higher doses of dutasteride may not significantly increase hair growth due to diminishing returns, and topical finasteride is suggested as an alternative for some.

      community Creatine is the opposite of minoxidil !

      in Research/Science  322 upvotes 4 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 Massive study on finasteride side effects released

      in Finasteride/Dutasteride  83 upvotes 3 years ago
      The release of a study on 5a-reductase inhibitors (finasteride and dutasteride) which showed an increased risk of depression, dementia, decreased libido, and reduced semen load as potential side effects; discussion around other forms of hair loss treatments such as topical minoxidil, RU58841, or opting to accept baldness; and advice to consider professional help for deeper issues related to hair loss.
