Interdigital pilonidal sinus is a rare occupational disease related to work with short hair. Hair dresser's disease is the interdigital pilonidal sinus encountered in male barbers. A case of pilonidal sinus in the interdigital web is reported. ⋯ There were neither complications nor recurrence in the third month after excision. We propose that surgical excision is inevitable and that any primary treatment can improve the patients' postoperative comfort. Thus, primary closure or closure with a flap, instead of secondary healing, should always be the first choice of treatment for a defect due to excision of an interdigital pilonidal sinus.
