How do I create an alpha hair texture?

okay, okay, I hope you can understand it then one day
you must look at the image and understand it
you have to draw the hair
It's like the clothes you have to draw by geometry, common sense ...
the hair is a brush
a brush in photoshop to be exact
when a person draws in real life he makes the character's hair with brushes, with pencil ... well that's the same thing that you have to do
Do you know the zbrush program? That may help you

that's why I now understand why some creators say: do not use my texture

And of course, it has cost a lot of work, little hair for little hair in clear photoshop!
