Two types of hair loss not related to the hair growth cycle are trichotillomaniaand traction alopecia.
Trichotillomania is a compulsive behavior in which a person pulls hair out of the scalp, eyelashes, or eyebrows. There is usually mounting tension before pulling the hair and a feeling of relief afterward.
Traction alopecia involves hair loss around the edge of the hairline and is especially noticeable around the face and forehead. It is caused by your method of hairstyling. Certain hairstyles can pull hair too tight; for example, tight braids or tight ponytails can cause hair loss.
