I have been using it for about 3 months. I am 67 and it was prescribed for frequent UTI's. I was having them constantly, I went to a urologist, he really found nothing because they had stopped. Before I saw the urologist I saw my gynecologist to make sure everything else was okay. He prescribed entrance. Perhaps it has helped the thinning of tissue and thus no infection? But I simply cannot lose my hair. Comments welcome.
