Overview
Trichotillomania is repetitive twisting and twirling of the hair. The hair loss is usually in a well-defined area with shortened, broken-off hairs and early regrowth of hair. The scalp is the most commonly involved site, but eyelashes and eyebrows may also be involved. The hair loss can also be patchy and poorly defined.
