Problems with particles

Hi everyone,

I’m creating for the first time characters with hair.

I’m using vertex group to specify where I want the hair, and till here it’s ok. The problem is that when I use children (working only with particles is not an option) some black dots appear on the final rendered image where they shouldn’t be, i tried adjusting everything on the children menu but it ain’t working. When I render from another view the dots are somewhere else. I just don’t know what to do now…

I thought of vertex paint but I don’t know how to make it and if it would solve the problem.
