This happens with most hair cuts depending on gear. It's a nuisance but personally I'd rather devs spend more time bringing out more gear than trying to fix clipping issues.
There is more of an issue with the 2nd and 3rd new haircut in which the back of the head is just completely flat making it look a bit like a bowl.
