       | Did a quick search for "hair" since in my experience the most

       | before heading to class. Always left me looking disheveled). It

       | (the person in most of these figures has a buzz cut) than other
       | e-tattoo methods but they do note:

       | neuroscience research is crucial, as traditional EEG electrodes
       | are often unreliable on individuals of African descent, resulting
       | in suboptimal patient experiences and outcomes in clinical
       | settings.69,70 Curly hairs tend to push against the EEG cap,
       | reducing contact between the electrodes and the scalp, leading to
       | a poor contact impedance.71 Developing on-scalp digital printing
       | for different hair types should prioritize bridging this
       | important gap.
