What is comma hair?

The answer

Comma hair is a fringe that curves inward and sweeps across the forehead, resembling a comma. It is usually paired with shorter, tidier sides so the fringe stands out. The fringe commonly sits between the eyebrows and eyelashes, and the curve can come from the cut and blow-drying alone. Enough length at the front, softened ends and a little lift at the roots are what make the shape hold.
