I draw around the lines with a 0.1 stroke and no fill to match the thickness and shape to the line, and then press Shift+X to swap the fill and stroke, removing the stroke and adding a fill. Then I do some extra cleanup to make sure the thickness is consistent with previous lines I've drawn.
The ends of the hair are sharp because there is no stroke applied. Strokes add a blunt end to single node points. If you remove the stroke and only have a fill, the endpoints will be sharp.
Attached is the outline of the shapes so you can see how I drew around the original lineart and how the separate hair shapes are hidden within each other. The picture in the previous post is with the stroke removed, and fill applied.
