Looking for guidelines on creating hairstyles

[nilead]

 Pretty much self-explanatory, there is plenty of guides on how to create armor for TES5, however my search for hairstyle one turned out fruitless. 

Im new to this, so the more details - the better. Ive got a mesh almost done (using Blender), however im in the dark on where to move from there. 

There is a ton of other questions, like if there any hard limitations for polygon count (currently i just try to keep it in line with one of KShairs i imported as en example), what are the requirements for it to be convertable to HDT-PE, etc etc. Long story short - i need information, dumbed down to fool-proof if at all possible.
