Trichodynia is a condition where the patient experiences a painful sensation on their scalp. The pain sometimes is described as burning. Often there is an underlying psychosomatic cause, such as stress, depression or anxiety. Only a few studies have been conducted on this condition. A theory behind the condition is that nerves innervating scalp hair follicles send pain messages back to the brain when the follicle no longer has a hair in it, in a similar way to phantom limb pain. Another theory is that people who have this condition (sometimes called "ponytail syndrome") have super-sensitive nerves in their scalp. A possible treatment is to halt hair loss in the patient, however it is important to understand and address any underlying psychologic comorbity. ==References== *(hair loss and Trichodynia ) *(Trichodynia, hair loss and patient gender ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trichodynia」の詳細全文を読む スポンサード リンク
