    TLDR Aging skin causes inflammation that affects the whole body.
    The review article "The Skin and Inflamm-Aging" explores the concept of "inflamm-aging," which is characterized by chronic low-level systemic inflammation linked to aging. It emphasizes the skin's role as a barrier and its involvement in immune responses, noting that age-related impairments in skin barrier function contribute to systemic inflammation. This inflammation exacerbates age-related conditions and is influenced by factors like UV exposure and oxidative stress. The document highlights molecular mechanisms, such as reduced aquaporin-3 and calcium-sensing receptor levels, which impair skin hydration and repair. Understanding these processes is crucial for developing therapies to mitigate inflamm-aging and improve skin function in the elderly.

They also experienced side effects from other treatments. They are considering cutting off their hair and stopping the medications if there is no improvement in three months. Other users suggested trying different treatments and getting a blood test to check for underlying conditions.

      A user who shared progress pictures of their scalp using a microscope camera, demonstrating the difference between healthy and miniaturized hair. Various explanations for the cause of this were discussed, such as DHT build-up in scalp sebum causing an autoimmune response leading to inflammation and eventual hair loss, with some suggesting a do-it-yourself treatment involving adding ascorbic acid powder to shampoo.

      community Androgenetic alopecia is a skin disease: DHT-mediated skin disorders

      in Research/Science  61 upvotes 2 years ago
      Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.
