Studies show that 38% of patients who took 320 mg of saw palmetto every day for two years showed improvement in their hair loss, compared to Finasteride’s effectiveness rate of 68%. It means that in direct comparison, saw palmetto appears to be less effective compared to Finasteride. However, you should be aware that saw palmetto increases its effectiveness with increasing doses. And also, unlike Finasteride, it shows no particular side effects whatsoever, which is why it appears as a new, robust alternative to Finasteride for treating hair loss.
