Alopecia Areata, Causes, SIgns and Symptoms, Diagnosis and Treatment.

Summary

Alopecia areata is an autoimmune disorder characterized by hair loss in small patches, primarily affecting the scalp but potentially occurring anywhere on the body. The condition results from the immune system attacking hair follicles, leading to varied hair loss severity. Symptoms include distinct hair loss spots, thinning hair, and potential nail changes. Diagnosis involves assessing symptoms and may include scalp biopsies or blood tests. While there is no cure, treatments such as minoxidil, steroid injections, and lifestyle adjustments can promote hair regrowth. Individuals with celiac disease may see improvement with a gluten-free diet.
