I used minoxidil for over two weeks then stopped using it, now that I stopped I'm losing more hair than before, is it temporary?

Yes, there is an initial hair shed with Minoxidil and this is temporary. Keep in mind, it takes 6 months to see results with Minoxidil. I  recommend getting a formal evaluation with a hair loss expert to go over your condition and advise you on best treatment options and shampoo recommendations. There are great non-invasive options like prp/progesterone which works well with Minoxidil/Finasteride. Hair transplant is an alternative. See an expert. Best, Dr. Emer

Minoxidil helps to stopping hair loss and thickening of hair although it may cause a little loss at beginning . I recommend you to use minox for at least 6 months to get any  benefit. But remember that  ıf you stop to use minox after a long time usage, you may experience a fast thinning, even loss of hair because of ending action of active ingredient. That phenomena leads people to a misconception that minoxidil causes hair loss after  stopping to use it. 

Minoxidil causes an immediate release of hairs that were supposed to come out in a few weeks but end up coming out early. For most people, it's temporary and the shed lasts less than 4 months. See  your physician if worried.
