    TLDR Hormones and genetics play key roles in male and female baldness, which can affect mental health and may be linked to other health issues.
    The document from April 1, 2014, provides a comprehensive review of the endocrinology of androgenetic alopecia (AGA), commonly known as male pattern baldness, and its implications for both men and women. It explains the role of androgens, particularly testosterone and dihydrotestosterone (DHT), in hair loss, and the genetic factors involved, including a single nucleotide polymorphism (SNP) in the androgen receptor gene. The review includes studies with sample sizes ranging from 63 to 1,717 men and discusses the psychological impact of baldness, such as increased anxiety and decreased self-esteem, particularly in younger men. It also addresses the potential associations between AGA and health conditions like prostate cancer and cardiovascular disease, although findings are mixed. Female pattern hair loss (FPHL) is acknowledged as different from male baldness, with its own genetic and hormonal characteristics. Treatments for baldness, such as finasteride and minoxidil, are mentioned, with varying degrees of efficacy. The document underscores the complexity of AGA's genetic basis, its potential health implications, and the distinct nature of female baldness.

      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 Does finasteride/dutasteride reverse aging?

      in Chat  45 upvotes 4 months ago
      Finasteride and dutasteride can improve skin texture and reduce acne by lowering DHT but do not reverse aging. They may enhance skin and hair health for some, but can also cause side effects like dry skin and sexual dysfunction.

      community Why is it that low testosterone causes hair loss as well? How can I be balding?

      in Chat  158 upvotes 10 months ago
      The conversation discusses the confusion over low testosterone potentially causing hair loss, with users sharing personal experiences and knowledge about hair loss treatments like Finasteride. Some users suggest that hair follicle sensitivity to DHT, not testosterone levels, is the key factor in balding, and others discuss the side effects of hair loss medications.

      Antiandrogens and androgen inhibitors like spironolactone, finasteride, and dutasteride can treat hair loss and skin conditions, but they have risks and side effects, including potential harm to pregnant women and risks of cancer and heart issues. Herbal remedies also have antiandrogenic effects but lack safety validation.
