In most sleep labs, it is not recommended to wash your hair the next morning. This is because the electrodes attached to your scalp need to stay in place for accurate monitoring of brain activity during sleep. Washing your hair could potentially disrupt the electrodes and affect the quality of the data collected. It is best to wait until after the sleep study is completed before washing your hair. **

Hair accessories can be secured in a variety of ways depending on the type of accessory.
