Can someone explain how to make hair in blender...i heard with particles..
but...how do i manage to make èarticles look like hair??

try pressing the Vect button in the animation: particle menu. It makes the particles "long". you may have to tweak the settings a little

There is Excellent RipSting fiber generator.

But I'd bet this sort of questions are better asked on http://www.elysiun.com/ in the Q&A forum
