MIPS has a [**thorough, and interesting, take**](https://mipsprotection.com/science-technology/test-lab/) on its website about why they don't consider the neck in their testing which is always something that surprised me.
They don't appear to have a write-up about hair. My understanding - which admittedly comes from someone selling MIPS, is that you have to consider the amount of pressure in an impact. Essentially the hair is an unreliable slip plain because it's being pushed down/held in place by force whereas the MIPS systems can still rotate consistently in the same circumstances.
