The hardest aspect of hair growth is the waiting game because even if you follow this advice, it will take time to see the results. Engelman suggests staying the course. "That's the worst part about hair: it's so slow to see results. All the actions aren't very reinforcing because everybody expects to see results immediately. It takes a while because of the hair growth cycle and all the action is at the follicle base under the skin's surface. Stay with it, though!"
