No Minoxidil loses its effectiveness after 2 years. It only helps to regrow "new" hairs for 2-3 years and after that you will need to use it everyday to keep what you regrew.
Oh, and i've been using Xandrox 15 for about 5 months and seeing slow regrowth at the hairline but overall hair thickening is going slowly too. I definetly noticed better and faster results when switching to Xandrox 15.
Minoxidil (Rogaine/Xandrox etc) does not lose its efficacy after 2-3 years, it carries on doing the same job (which is to keep hair in the anagen, or growth, phase) for as long as you use it.
