Minoxidil and caffeine are discussed for hair loss treatment. The user questions the logic of combining them due to their opposing effects on adenosine receptors.
Oral dutasteride is the most effective for hair regrowth, followed by oral finasteride and minoxidil. Topical finasteride combined with minoxidil is recommended for those avoiding systemic DHT reduction.
Caffeine shampoos show comparable results to Minoxidil and may enhance its effects when used together. Caffeine can be detected in the scalp up to 24 hours after a 2-minute application, making it an affordable treatment option.
