When using a hair dryer

They say that using natural air or cool air is best for minimizing hair damage, but I find myself rushing to dry my hair with warm air because I'm always in a hurry to get dressed and head out. Afterward, I can definitely feel my hair getting worse, and it becomes frizzy, perhaps because too much moisture has been lost. Feeling a bit guilty, I apply hair essence to the ends before heading out. Are you all in a similar situation?
