    TLDR Metformin promotes hair growth by affecting cell growth and protein signaling related to hair growth.
    In a study published in 2019, researchers investigated the effects of metformin, an AMP-activated protein kinase (AMPK) activator, on hair growth by examining its impact on dermal papilla (DP) and outer root sheath (ORS) cells. The study found that metformin treatment increased the proliferation of these cells and Ki-67 expression, a marker for cell proliferation, in ex vivo hair follicle cultures. Additionally, metformin treatment resulted in increased AMPK phosphorylation, which led to decreased degradation and increased nuclear accumulation of β-catenin, a protein involved in hair growth regulation. The conclusion of the study was that metformin promotes hair growth through the AMPK/β-catenin signaling pathway in vitro, suggesting that AMPK activators could potentially be used to treat alopecia. However, further research is needed to fully understand the potential of this treatment.

      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.

      The conversation discusses the potential of topical rapamycin, metformin, and alpha-ketoglutarate (a-KG) for hair growth, with skepticism expressed about their effectiveness based on personal experience and existing use. It also mentions AICAR, known as cardarine or GW, which is not suitable for long-term use due to cancer risks in animal studies and its similarity to metformin.

      The conversation is about whether it's safe to take Metformin for weight loss and Finasteride together, with the concern that Finasteride is not commonly used for hair loss treatment in the user's location, and their doctor is not knowledgeable about it.
