Sometimes, and in a few cases only (around 5% of the patients using the treatment), a hair loss may occur in the part treated with Minoxidil. Usually, it is just a transitional loss which often starts between two weeks and two months after the beginning of the treatment. It may be due to the acceleration of the loss process of those hair which where going to fall soon. I advice you to wait for two more months and then the beneficial effects of the Minoxidil should be visible. If this does not happen, you will have to stop it and possibly start to use Propecia.
