Growing hair is a continual process with 3 distinct phases lasting anywhere from weeks to years. Minoxidil will help revitalize hair follicles to move them from the resting to the growth phase and regrows hair with continued use. While the mechanism of action for minoxidil is still completely unknown, it is known that hair follicles gradually return to a dormant state after someone stops using the topical solution. The hair will most likely follow the hair growth cycle and will be lost gradually over time – it will not suddenly fall out. Think about your hair being similar to grass that doesn’t grow. When the grass is cared for with water and fertilizer, it is more likely to grow and become stronger. Once you stop applying the water and fertilizer the growth of the grass will most likely slow down and the grass may become dormant after a period of time.
