    TLDR Minoxidil with caffeine works better for hair loss than minoxidil alone.
    In a double-blind randomized clinical trial involving 60 patients, the study assessed the efficacy of a topical solution combining caffeine and 2.5% minoxidil versus a solution with only 2.5% minoxidil for treating androgenetic alopecia. The patients were split into two groups, with one receiving the caffeine and minoxidil solution and the other just minoxidil, applying 1 milliliter twice daily over 150 days. Results indicated that the combination treatment was more effective, showing a statistically significant increase in hair count from around day 120 compared to the minoxidil-only group. The study suggests that caffeine may enhance minoxidil absorption and improve microcirculation, as well as inhibit the 5a-reductase (5aR) enzyme, which contributes to hair loss. The findings recommend further research with a larger sample size to confirm the benefits of combining caffeine with minoxidil for this condition.

      A user is trying to reverse male pattern baldness (MPB) naturally by taking high doses of Vitamin D, improving diet, exercising, reducing stress, and other lifestyle changes, but plans to use finasteride if no results are seen in 60 days.

      The conversation discusses the potential benefits of topical caffeine for Androgenetic Alopecia (APA) and female pattern hair loss. While some studies suggest positive results, there's no reliable scientific evidence to strongly recommend caffeine compounds for hair regrowth.
