Problems with particle density.

I’m trying to make a character with a mane like a lion. I’ve tried using vertex groups, but it hardly works correctly. The particles are mostly were I did not tell them to be. They are WAY off of the verticies specified in vertex groups.

I’ve also tried using a texture, but the particles do not concentrate on that one area with enough particles. There aren’t enough particles in that one spot.
