Syncope associated with hair-grooming

We report 20 girls who experienced episodes of unconsciousness while standing for hair grooming. The episodes were syncopal in character, electroencephalograms were normal in most cases, and at least 11 of the 20 had definite episodes of syncope in other circumstances. A number of these girls underwent extensive diagnostic testing. We consider this a form of situational or reflex syncope, perhaps related to orthostatic hypotension, the recognition of which may spare unnecessary diagnostic and therapeutic interventions.
