    GlossaryMendelian randomization

    uses genetic variations to infer causal relationships in biology

    Mendelian randomization is a research method that uses genetic variations to study the causal effects of a modifiable exposure (like diet or lifestyle) on a disease. By leveraging the random assortment of genes from parents to offspring, it mimics the design of a randomized controlled trial, helping to determine whether an observed association between a risk factor and a health outcome is likely to be causal rather than due to confounding factors.

      community Hair Loss Causes Depression. Not Finasteride.

      in Research/Science  188 upvotes 4 months ago
      Finasteride and Dutasteride do not cause depression or mood disorders; hair loss itself may be a more significant factor. Some users experience side effects from Finasteride, but it is generally well-tolerated.

      community Genetics are so weird and unpredictable

      in Minoxidil  118 upvotes 1 year ago
      The user experienced male pattern baldness starting at 18, tried finasteride with no success, and switched to dutasteride, which halted hair loss. Minoxidil had no effect for them, while their brother, who didn't use AR inhibitors, maintained a juvenile hairline and successfully grew a beard with minoxidil, highlighting the unpredictable nature of genetics in hair loss and treatment response.

      community Proposed new pathogenesis model for androgenetic alopecia (AGA)

      in Research/Science  7 upvotes 2 years ago
      The conversation discusses a new model for understanding androgenetic alopecia (AGA), linking it to dietary and lifestyle factors similar to PCOS, and highlighting the role of DHT, vascular damage, and inflammation. Treatments mentioned include Minoxidil, finasteride, and RU58841.

      community Genetic testing to determine individualized hairloss treatment?

      in Research/Science  10 upvotes 3 years ago
      A user discusses a company, Roots by Genetic Arts, that offers a genetic test for hair loss to create personalized treatments, and is curious about its legitimacy and the science behind it. The company tests 16 genes related to hair loss and compounds a topical treatment based on the results.

      community I want to be a science experiment

      in Research/Science 9 months ago
      The user plans to use a "nuclear protocol" for hair improvement, including topical minoxidil 12.5%, topical finasteride 0.1%, and tretinoin 0.05%, with microneedling once a week. They have seen improvements with minoxidil and are seeking opinions on their approach to achieve thicker hair.

      community CRISPR treatment for AGA on the horizon after approval for blood disorders

      in Treatment  9 upvotes 2 years ago
      CRISPR treatments for blood disorders have been approved, leading to discussions about its potential for treating hair loss (AGA). A study showed that editing a gene related to DHT sensitivity could lead to hair regrowth, suggesting CRISPR may eventually be used for AGA, but it's expected to be expensive and not soon available.

      community I want to sacrifice my hair in the name of science

      in Chat  12 upvotes 2 years ago
      The conversation discusses various theories of hair loss, including DHT sensitivity and genetic factors, with the user willing to use themselves for research due to having a hair loss gene but different hair loss patterns compared to their brothers. Specific treatments were not mentioned in the provided text.

      community Looks like a real cure to the root of baldness (DHT-induced senescence) was proven earlier this year

      in Research/Science  739 upvotes 3 years ago
      A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.

      in Research/Science  25 upvotes 2 years ago
      The post discusses a theory that hair regrowth after transplant is due to the angiogenesis process (new blood vessels forming), not because the transplanted hair is unaffected by DHT. The responses highlight the established belief in 'donor dominance' (the importance of the hair's origin in transplantation) and skepticism about the new theory.
