What causes alopecia areata?
Doctor's answer (1)
Dr. Wang Xiaoyan
Possible causes of alopecia areata include the following:
1. Genetic factors: Alopecia areata is closely related to genetics. If someone in the family has the condition, the individual's risk of developing it increases.
2. Autoimmune disorders: Abnormal immune system attacks on hair follicles, such as those seen in psoriasis or thyroid diseases, may lead to alopecia areata.
3. Mental stress: Prolonged psychological tension, anxiety, or excessive stress may disrupt hair growth and trigger alopecia areata.
4. Endocrine imbalances: Hormonal imbalances, such as abnormal levels of androgens, may affect the hair follicle growth cycle and result in alopecia areata.
5. Hair follicle infections: Bacterial, fungal, or viral infections of hair follicles may provoke alopecia areata.
