    TLDR Hair follicle stem cells and mitochondria are key for hair growth, and targeting their activity could lead to new hair loss treatments.
    This review article highlights the importance of hair follicle stem cells and mitochondria in hair growth and the hair cycle. Hair follicle stem cells, found in the bulge area, are crucial for the hair cycle and can differentiate into various hair follicle cells. They are typically inactive but can activate and contribute to the formation of anagen hair follicles. Mitochondria are emphasized for their role in stem cell activity, with studies on mice indicating that mitochondrial proteins like CRIF1 are vital for the hair cycle, and mitochondrial dysfunction can result in delayed or suppressed hair follicle development. The review suggests targeting mitochondrial activity in stem cells as a potential approach for creating hair growth stimulants and notes the need for more effective hair loss treatments, with further research on these stem cells possibly leading to better therapies.

      Hair becomes gray and thin as we age, and while most hair loss in older people is due to genetics, there's a chance for gray hair to regain color under certain conditions.

      The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.
