    TLDR Normal androgen levels need ACTH, and different mechanisms control adrenarche and gonadarche.
    This study examined plasma androgen levels in 45 patients aged 5.6-23.8 years with growth hormone deficiencies over 1-7 years. It found that mean plasma androgen levels were normal in isolated GH deficiency but lower in those with multiple pituitary hormone deficiencies, especially when ACTH was also deficient. The study suggested that adrenarche and gonadarche are controlled by different mechanisms and proposed the existence of a specific hypothalamic-pituitary adrenal androgen-stimulating hormone (AASH). ACTH was deemed essential for normal adrenarche. The study also noted that induced puberty with estrogens in girls did not affect plasma androgen levels or hair growth, suggesting dehydroepiandrosterone sulfate replacement for girls with hypopituitarism. Body surface was found to be as effective as bone age in interpreting plasma androgens in hypopituitarism.

      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.

      Key treatments for hair preservation include minoxidil, finasteride/dutasteride, and microneedling, with additional options like specific shampoos, oils, biotin, zinc, tretinoin, clascoterone, and low-level laser therapy. Maintaining a healthy lifestyle, reducing stress, and addressing nutrient deficiencies can also support hair health.

      A 19-year-old has been using finasteride, minoxidil, and microneedling to treat hair loss with no regrowth, feeling mentally affected by it. Advice given includes continuing treatment, considering a hair transplant, addressing potential vitamin deficiencies, and possibly switching to dutasteride or adding ketoconazole shampoo.
