Hair loss is quite severe; what are the possible reasons?
Recently, my hair has been falling out in handfuls while shampooing, and I feel quite worried. May I ask what are the possible reasons for severe hair loss?

Excessive hair loss can be caused by various factors. The following are some common reasons:
1. Genetic factors: If there is a family history of hair loss, individuals may also experience similar issues.
2. Hormonal changes: Events such as pregnancy, postpartum period, menopause, and thyroid dysfunction can lead to hormonal fluctuations, thereby affecting the hair growth cycle.
3. Poor nutrition: Long-term picky eating or dietary imbalances leading to inadequate nutrient intake can affect hair health and cause significant hair loss.
4. Psychological factors: Prolonged depression and high levels of mental stress can cause the body to produce specific hormones, affecting mental health and resulting in hair loss.
5. Medication side effects: Certain medications, such as chemotherapy drugs, antidepressants, and blood pressure medications, may cause hair loss as a side effect.
6. Unhealthy lifestyle habits: Excessive life stress and irregular作息 (作息 refers to rest and activity patterns) can lead to nervous tension, causing loosening of scalp hair follicles and significant hair loss.
7. Physical damage: Frequent hair dyeing, perming, using excessively hot hair dryers, and wearing tight hairstyles (such as braids or hair clips) can damage hair roots and follicles, leading to hair loss.
8. Diseases: Autoimmune diseases (such as alopecia areata) and chronic conditions (such as diabetes) may also be associated with hair loss.
If experiencing severe hair loss, it is recommended to seek medical treatment promptly.
