Dr Rassman, I have been using both rogaine and propecia for the past ten years. I think they have worked fairly well but I have read that rogaine becomes less effective over time. My question is it still worth using, does it have any negative effect if you continue to use it even if it does not seem to be growing as much hair as when it was first started. I don’t have any shedding due to its use and have always read that using them together is a good approach to fighting hair loss.
If it is working now and you’ve had success for a decade, I’d keep up with your daily routine. Why take chances? Do what you know best. If you discontinue its use now, you’ll lose any benefits you’ve had for all this time. Remember, new hair that has grown from minoxidil is dependent upon the drug and if it is withdrawn, it is highly likely that these dependent hairs will fall out.
