 [ Symptoms ] how bald do i have to be for rogaine to work for me can i use topical rogaine and propecia pills at the same time  how long does it take to see an improvement in my hair [ Disease ] this is a great question and there are actually several questions in there so i will try to address all of them for you first of all the sooner you start using the products whether it is rogaine andor propecia the better off you are because it is much easier to prevent the hair loss than it is to try to fix it afterwards so as soon as you think the hair is starting to shed whether it is in the temple area or in the crown that is when you start going the other good point is that using propecia and rogaine together is better than using either one alone so it does not become like one and one is two it is more like one and one is four or five so they are that much better together it takes about two to three months to begin to see results and in about two years you will get the maximum that you are going to get out of them so not only do these products help prevent hair loss they actually help regrow hair and over time you will see that continue and in about two years you will hit that stabilization point
