Which hair loss treatment is most effective among Follihair, Hairful, Keraglo Men, or finasteride tablets, and what are the recommended biotin shampoos for promoting hair growth?
Among the treatments you mentioned, finasteride is medically the most effective as it directly targets the hormonal root cause of male pattern hair loss. Follihair, Hairful, and Keraglo Men are nutritional supplements; while they support overall hair strength, they cannot stop genetic hair loss alone. Regarding biotin shampoos, they can improve hair texture and thickness, but because they are washed off quickly, they don't significantly stimulate new growth. For the best results, I highly recommend consulting a dermatologist.
