    GlossaryThyroid Hormone Receptors

    proteins in cells that bind thyroid hormones to regulate genes

    Thyroid Hormone Receptors (THRs) are proteins found in cells that bind to thyroid hormones, which are crucial for regulating metabolism, growth, and development. When thyroid hormones attach to these receptors, they influence the expression of specific genes, thereby affecting various physiological processes. This interaction is essential for maintaining normal metabolic function and can impact conditions like alopecia if disrupted.

      Diffuse hair loss and scalp biopsies

      community Diffuse hair loss and scalp biopsies

      in Research  692 upvotes 3 months ago
      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      community Why does finasteride stop working?

      in Finasteride/Dutasteride  26 upvotes 1 month ago
      Finasteride may seem less effective over time due to increased DHT sensitivity or aging, but it still suppresses DHT. Switching to dutasteride offers stronger DHT suppression but may increase estrogen levels.

      in Treatment  9 upvotes 5 months ago
      The user discusses their hair loss experience, exploring various hypotheses including thyroid levels, vitamin D, DHEA, nutritional deficiency, diabetes, seborrheic dermatitis, lack of nutrition to hair follicles, chronic inflammation, female pattern hair loss causes, cortisol, and prolactin levels. They are currently using finasteride, beta-sitosterol, and have tried topical dutasteride and microneedling therapy.
