Not combing, brushing, or styling immediately after a shower. Everyone's got their routine and habits, but one thing to remember is that your hair, once washed, is like a blank canvas. Just like paint starts to dry after applying, so does your hair start to dry and set after showering. Thus, the earlier you start styling your hair, the easier it will be, and the more control you'll have. At the very least brush your hair into place—even if it’s just with your hands—so that it dries in the right style.
