I'm in composer mode when I try to change Ruby's hairstyle, and I can't seem to get it to work properly:
74% of original size (was 676x19) - Click to enlarge
Seems a bit off, but it looks pretty decent. When her head moves towards the viewer, the hair still holds...kinda, but when she looks to the side, this happens: 
74% of original size (was 676x19) - Click to enlarge
Then more to the side:
74% of original size (was 676x19) - Click to enlarge
I've tried with Ruby's head already facing the viewer, and the same thing happens, no matter which hairstyle I change it to. I seem to be having trouble with hair changing in general; even trying out the other hairstyles from the pack Ruby's from does this.
Considering there are no tutorials for when this happens, it must be on my end (which I totally agree with). What am I doing wrong here?
