Traction alopecia is a type of hair loss that occurs when hair is continually pulled taut due to tight hairstyles. On top of wearing hair in tight up-dos, traction alopecia is more likely to occur if hair has been treated with chemicals or heat styled on a regular basis. Traction alopecia differs from other forms of alopecia, such as alopecia areata, which is a form of autoimmune disorder.
Besides hair loss, other symptoms of traction alopecia include itching, soreness, scaling, redness, and inflammation of the hair follicles (also known as folliculitis). In more severe cases, you may even notice pus-filled blisters appearing on your scalp.
