make sure your hair is clean and dry for the test. We recommend you wash your hair the morning of the test,
as many people produce oil from their scalp during sleep, which often makes it difficult for the electrodes to pick up a good connection.
You cannot use mousse, gels, or hairspray the day of the test as this also affects the connection of the electrodes. No braids, extensions or cornrows are permitted and hairpieces will need to be removed at the time of testing. Also, no dreadlocks are permitted. Please do not wear turtleneck tops or hooded sweatshirts.
