Should a client wash their hair before an EEG?

Washing the hair before an EEG is essential because clean hair ensures that the electrodes can adhere properly to the scalp and that the signals from the brain are not interfered with by hair products such as oils, gels, or sprays. When the hair is clean, it reduces the chance of artifacts in the readings, which could compromise the quality of the EEG results. Therefore, advising a client to wash their hair before the procedure is the right approach to ensure accurate and reliable data collection during the EEG.
