The Odyssey III is designed for top-of-the-head bonding as well as the conventional extended and daily wear methods.
The Odyssey III systems uses 100% human hair, which is infused into the cortical layer of skin using the new knotting technique. The cortical layer is then merged to the epidermis layer of the scalp to form a skin-tight fit without bumps of ridges. As though nothing existed other than a full head of hair on your scalp. The front is so natural thai it's totally undetectable.
The cortical layer is make of a permeable, co-polymer material which is thermal conductive. this allows the cortical layer to stretch and breathe as needed, plus to be as thin as possible.
