Hey. I know you've already solved your problem, but I suggest using XGen next time. nHair is already outdated and, in my opinion, XGen is far easier to use.
Oh gawd yes, I completely agree with Gem, XGen all the way. You would have a much easier time with a lot more control and much better end results. https://www.youtube.com/watch?v=1Fs6rle_IbE
