    TLDR Hair ages due to various factors and treatments like minoxidil and finasteride can help, but more research and better public awareness are needed.
    The document from 2007 explores the phenomenon of hair aging, including changes in the hair shaft and follicle that lead to graying and decreased hair production, as seen in androgenetic and senescent alopecia. It reviews the esthetic and biological aspects of aging hair, the impact of intrinsic and extrinsic factors like genetics, UV radiation, and smoking, and current treatments such as minoxidil, finasteride, and hair transplantation. The paper also discusses the psychological effects of hair loss, the role of DHT and androgen receptors in AGA, and the need for further research and public health education. It highlights the importance of scalp sun protection and the use of antioxidants, and notes the varying effectiveness of treatments like finasteride and minoxidil, especially in women. Additionally, 38% of patients at the Palm Springs Life Extension Institute saw improvements in hair thickness and structure with recombinant human growth hormone treatment. The document emphasizes the potential of tissue engineering and targeted delivery of active compounds to hair follicles, despite existing challenges. It references several clinical trials and studies on the efficacy of minoxidil and finasteride in treating patterned hair loss but does not specify the number of participants in these studies.

      Minoxidil with alcohol and propylene glycol was more effective than non-alcohol versions, and RU58841 worked best in a non-water-based solution. Oral finasteride showed better results than topical, despite side effects; microneedling and tretinoin worsened hair loss, and PRP was only helpful when younger.

      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.

      Hair loss treatments like finasteride, minoxidil, and dutasteride work but have side effects. A permanent cure is still not available due to the complexity of hair loss and limited investment.
