Speaking for myself, I have a guess "fetish" for having my hair pulled, so in a rule match or general fight it takes a lot more pulling to really bother me i guess you can say, but I have seen and dealt with women who you touch their hair and they scream, so in general refusing to react or cry out is like a sign your oppoenent or rival is not hurting you, it is kind of a tactic make the one doing the pulling think they aren't hurting you enough kind of,s oi agree it is kind of a double effect, in my mind not having a "major "reaction can really play on your oppoenents /rivals head I been in situations where i shook another woman by her hair and she was able to stare me in the face after and smiled I was thinking "How is that not making you scream" and next hing i knew my scalp was buring, but in any situation it comes to your pain threshold the more you can with stand the less reaction to it, and if you think about the torture we put our scalps and hair through daily, brushing, curling irons, hair dryers, pulling our own hair into buns and pony tails and the vitamin shampoos and vitamins that build stronger hair and hair cells
