I heard it had something to do with “alpha” but I can’t seem to get it to work. Anybody got some know how on this stuff.

You can use an Blended Alpha
Here’s a tut: http://mediawiki.blender.org/index.php/Manual/PartXIII/Particle_Hair
[EDIT] Haha I got before you guys. Oh didn’t looked at your example how to make hair like that is probably like someone said further down. The tut is on making particle hair.

You have to use a color map with your hair texture and a black and white alpha map. The black will make the transparency.
Look at this sample:
