Ok thanks for all of the advice and help. The hair room really does sound like the only possibility to achieve what i really want. and i think i will purchase Jolie Fille hair, mainly as the skull cap is exactly what i want to grow the hair from. 

Although it would not look as good one way i could animate the hair using the Jollie Fille hair would be to set a key frame at the start of an animation with the hair in a certain pose and then at the end of the animation i could add one of the Jollie Fille's hair morphs, so that will animate the hair from point A to B and could look ok if done right.

In terms of the sculp mesh i cannot see anyone having a problem with what i am doing, as i am not trying to make any money from this. It is for my own personal use, but if things were to go further then i would definetly ask permission.
