Alopecia areata, also known as circular hair loss or follicular degeneration syndrome, is a common phenomenon of hair loss. Its causes mainly include the following:
- Genetic factors: Alopecia areata may be related to heredity. If there is a family history of alopecia areata, the risk of developing the condition is relatively higher.
- Mental stress: Long-term mental tension, anxiety, excessive stress, and other psychological factors may also trigger alopecia areata. Psychological stress can interfere with the body's normal functions, including hair growth.
- Autoimmune diseases: Alopecia areata is sometimes associated with autoimmune diseases such as psoriasis and thyroid disorders. These diseases may cause the immune system to mistakenly attack hair follicles, leading to hair loss.
- Follicle infection: Bacterial, fungal, or viral infections of the hair follicles, resulting in hair loss, are also possible causes of alopecia areata.
Treatment options for alopecia areata include topical corticosteroids, light therapy, oral medications, and others aimed at promoting hair regrowth and suppressing immune system attacks. However, treatment outcomes may vary from person to person.
