Naah. It is possible, but I would not use the extrude technique on that hair. On this example I would first create a Cone with subdivision axis on 5, and delete the faces under it. Then I would bend the cone downwards (as on the image), duplicate the cone and paste it on the areas where the hair should be. When you have placed the cones and formed them, you combine them and merge the vertices. =) - Sepo
