According to my limited knowledge, I don't think you'd lose anything. Based on what I have read so far, taking 3-4 weeks off once every 5-6 months is a good thing. That way, you give your body time to forget the tolerance of those chemicals in/on your body. I started my regimen 2 months ago, and I plan to take 2-3 weeks off completely at 4-5month.JimH88 said:I've been taking Rogaine, Nizoral, Propecia for about 5 months and I had reordering difficulities which led me to be off Propecia for nearly a month? Is that going to be like starting back over to day 1 before I'll see any results?
