Noobie materials question

hello all…

I have a noobie materials question for Blender…

Is it possible to have a texture/material/picture like this:


And make it so all black colors are alpha = 0, so only really the hair will be displayed and the black part of the mesh will not?

I know how to do this on unity… but I want use this with BGE, so want to do this in blender.

thank you for help…
