Great question. I don't know which Finasteride studies are you talking about. No, the results are not the same of Finasteride 1 mg vs .25 mg. I will trust the Merck studies. There is a 1999 Merck study that compared Finasteride 5 mg vs I mg vs 0.5 mg and .25 mg vs placebo and one of the results showed that the patients on Finasteride 1 mg had 18% more hair count vs .25 mg. But and I don't know why, the patients on Finasteride low dosage had more "Adverse Events" than the high dosage. Also, the study showed minimal difference in the hair counts of Finasteride 5 mg vs 1 mg. I have been recommending Finasteride I mg or 0.25 mg daily to my patients for many years with very, very few adverse events and great results to stable the hair loss and hair regrowth.
