I have been on topical minoxidl for over 6 years now and have been on 1.25mg oral finasteride for over 3 years now. The topical minoxidl provided regrowth the first year but now has just flatlined the last few years. My hairline has staying the same over the years but i have slowly lost density. I was considering switching to oral dutasteride and oral minoxidl. Would this be a good idea and how should i go about it? Straight switch or slow introduction of the new medication?
