A mother of a college-aged son, who began losing his hair in high school, is concerned about his son's junk diet and excessive consumption of junk food, juice, and soda. His pediatrician dismissed her concerns, but now that he is an adult, there is nothing more to do. The most supportive thing for the mother is to listen to her son's concerns and provide help when asked for. While there are many options for hair treatments and resources for dietary assistance, parents should be proactive about these issues.
