In most cases, hair loss in adolescents will regrow. The hair growth cycle is divided into the anagen (growth) phase, telogen (resting) phase, and exogen (shedding) phase. Normally, it is a natural physiological phenomenon to lose about 100 hairs per day, which generally does not require excessive concern. Causes of hair loss in adolescents may include heredity, lifestyle habits, malnutrition, and scalp-related issues. For example, unhealthy lifestyle habits, such as an imbalanced diet, excessive stress, and insufficient sleep, can all affect hair health. Long-term malnutrition, especially deficiencies in iron, zinc, vitamin D, and other essential nutrients, can also impair hair growth and lead to hair loss. To promote hair regrowth, adolescents can take several measures. First, improve lifestyle habits by maintaining regular作息 (作息 translates to作息 schedule) and a balanced diet, and avoid excessive fatigue and high levels of stress. Second, maintain scalp cleanliness and proper care by choosing shampoo and conditioner suitable for one's hair type. If the hair loss problem is severe, medication treatment under the guidance of a professional doctor may be considered.
