Yes, when we started Sens.ai this was one of the first issues we solved for. Sens.ai's CEO, Paola has thick long hair and has first-hand experience with the difficulty at clinics with her hair and electrode signal quality - even with goop. Put simply if you can part your hair in the middle and see scalp then you can use our headset. Also the headset is designed to fit comfortably on different heads. The frame of the headset fixes to different head circumferences and the earphones move to provide more or less height. All of our product details are available on www.sens.ai.com/product.
