Catherine has very long straight hair. A shaved flattop will be a big change. Her ponytail is buzzed off at the back. Clippers buzz all of the back and sides close. The top is then taken down with clippers. Shorter and shorter the falttop goes. The sides and back are rebuzzed with zero clippers. Shaving cream is added and the back and sides are shaved smooth. That is one incredible flattop you have, Catherine.
