    TLDR The man had myotonia, which caused delayed hand grip relaxation.
    In 2007, a 31-year-old Caucasian man was reported to have presented to the hospital with weakness in his arms and legs, six weeks after sustaining burns to his right hand. His medical history included hypertrophic cardiomyopathy, androgenic alopecia, and abdominal pain. Physical examination revealed a slim male with frontal alopecia and wasted facial and proximal limb muscles. His reflexes were preserved, and sensation was intact. However, his hand grip relaxation was delayed, a condition known as myotonia. His haematological and biochemistry tests were unremarkable, but left ventricular hypertrophy and lateral T wave inversion were present on the electrocardiogram.

      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.

      The user experienced hair loss despite using Fin and Min for 12 years and switched to Dutasteride, RU58841, and Keto scalp serum, but shedding and itch persist. They are considering increasing Dutasteride to 2.5mg and questioning the necessity of a scalp biopsy, with mixed opinions on its usefulness.

      The user has been using finasteride, minoxidil, and nizoral for hair loss but hasn't seen regrowth, only maintenance. They are considering switching to dutasteride, which is believed to be more effective, but are concerned about potential side effects.

      in Research/Science  81 upvotes 1 year ago
      The conversation is about the role of testosterone in hair loss and the effectiveness of different treatments. The conclusion is that DHT is the main culprit for hair loss, and finasteride has been proven to work long-term in maintaining and regrowing hair. Testosterone may have a minor effect, but it is not the primary cause of hair loss.
