Alopecia areata, also known as circular hair loss, is a common non-scarring hair loss condition. Its occurrence is mainly attributed to the following factors:
1. Genetic factors: Individuals with a family history of alopecia areata have a higher risk of developing the condition.
2. Immune system dysfunction: The immune system of patients with alopecia areata may mistakenly attack hair follicles, leading to hair loss.
3. Psychological stress: Prolonged mental tension, anxiety, or significant life events may trigger or exacerbate alopecia areata.
4. Hormonal imbalances: Endocrine disorders such as thyroid dysfunction and polycystic ovary syndrome may be associated with alopecia areata.
5. Infection and inflammation: Bacterial or viral infections or scalp inflammation may trigger alopecia areata.
Treatment options for alopecia areata:
1. Medication therapy:
Topical corticosteroid creams or injections can suppress local immune reactions and promote hair growth.
Oral medications, such as minoxidil and cyclosporine A, can help improve immune function and promote hair growth.
Antihistamines may be used to control associated itching.
2. Phototherapy: Exposure of the scalp to ultraviolet light can reduce inflammation and promote hair growth.
