Trichotillomania (TTM) is a compulsive hair-pulling disorder that causes people to pull out their hair from any area of the body. It can range from occasional light pulling to regular removal of large portions of hair. TTM is classified as an impulse control disorder and is often triggered by stress or other stimuli. Common signs include hiding bald spots with wigs or styles and pulling when hands are free during other activities. While there is no cure, treatment focuses on preventing pulling through techniques like bandages or fidget toys and avoiding confrontation about hair loss.
