    TLDR Men with hair loss have more DNA changes in back-of-head hair follicles, possibly protecting them from thinning.
    The study found that men with androgenetic alopecia (AGA) have higher levels of DNA methylation of the androgen receptor (AR) gene in occipital hair follicles compared to vertex follicles. This may protect occipital hairs from miniaturization and hair loss. The study suggests that this finding could lead to the development of therapeutic strategies for AGA, but further analysis is needed.

      community Why is dht bad for scalp hair but good for hair on the rest of body?

      in Satire  109 upvotes 1 year ago
      The conversation discusses why DHT (dihydrotestosterone) negatively affects scalp hair but promotes growth elsewhere on the body. Various opinions include genetic predispositions, differences in hair follicle reactions to DHT, and the potential role of Omega-3 in reducing inflammation and promoting hair health.

      A 29-year-old woman is experiencing gradual hair thinning since age 15, suspects Androgenic Alopecia, and has tried 5% minoxidil with little success. She has purchased various hair loss treatments including minoxidil, dutasteride, finasteride, and spironolactone, but is cautious about starting them due to potential interactions with her ADHD medication.
      Diffuse hair loss and scalp biopsies

      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.
      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 1 month ago
      FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.
