Hair systems get pretty expensive to develop and implement pretty quickly. Even the higher end apps have struggled with getting believable hair. And a lot of it comes down to individual user skill.

Keep in mind also that hair in higher end apps is often extremely complex and even has its own rig at times. IIRC, the hair models used in Disney's Frozen - the main girl had something like 80 different hair rigs, after having an application designed specifically for her hair (talk about a high-maintenance female, lol).

However there are some artists that have done some nice hair work in Poser and DS with Z-Brush's fibermesh.
