There are lots of brushes in brush palette, which one to chose? because when i try these steps i don't exactly get this pointed end like hair.. its shape is all same from start to end. And one more thing i want to ask when working with zoom, i get the hair really big i mean we cant minimize the brush size from 1px.
I usually used the regular, round brush, but you can of course experiment. As for the endings, when you switch to pen tool, right click > window pops up > pick 'brush' and make sure 'simulate pressure' is also checked, then it should work fine
