    TLDR Cytokines and neuropeptides are key in controlling androgen levels, affecting skin and hair conditions.
    The 2000 document examined the complex regulation of adrenal androgens, particularly DHEA, and their impact on skin conditions such as acne, hirsutism, and androgenic alopecia. It detailed the role of the pituitary hormone ACTH, as well as an intraadrenal network involving immune cells, cytokines, and neuroendocrine factors in the regulation of these hormones. The skin's ability to metabolize androgens and its own neuroimmune network were also discussed. Dysregulation of androgens can lead to various skin disorders, and the document emphasized the importance of understanding these regulatory networks for developing new treatments. It concluded that cytokines and neuropeptides within the neuroimmunoendocrine networks of the adrenal gland and skin are crucial in regulating androgen production, with cytokines like IL-6 and TNF-α potentially exacerbating hair loss by stimulating androgen production and altering the hair cycle.

      The conversation discusses whether to use finasteride for hair loss, considering its role in inhibiting DHT and 5AR, which can affect brain function and mood. Some users report anxiety and depression from finasteride, while others do not experience these side effects and emphasize the importance of DHT for brain and prostate 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.
