What is alopecia areata?
Alopecia areata is an autoimmune disorder that causes patchy hair loss when the immune system mistakenly attacks hair follicles.
This condition disrupts the normal hair growth cycle and can lead to sudden bald spots on the scalp or body. It affects both men and women and often emerges without warning.
Red light therapy may help reduce inflammation associated with alopecia areata and support the regeneration of affected follicles. While not a cure, light-based treatments have shown promise in improving hair density in some cases.
