I've imported my own hair models as per the tutorials. (Import as accessory, fitted onto Female neutral base then used transfer skin weights to create the hair asset. Add to Custom Content tab)


The problem I have is that when reused on another character (a headshot model I've created) kinks appear in the hair strands:



What can I do to either remove these on the new model or, ideally, fix the original 'master' so that it can be applied to any model?

I've been looking at the Fixing Visual Defects videos, i.e. manually painting Skin Weights, but I'm unsure how to apply the techniques shown for clothes on my hair strands.
For example, when I select some of the problematic vertices I just see a simple value of 1 on just one bone (CC_base_Head) and the same for the surrounding vertices:


I don't understand why the kink is being created.
Any help or advice with applying skin weights to hair would be very much appreciated.
