Whenever someone wears a hat mog it cuts off their hair and sometimes even shaves their head completely making them completely bald.
There are a number of npcs in the game wearing hat and headgear mogs which we players have access to, but the hat does not cut off their default hairstyle. We need this option for players. Enough with the weird short/shaved hair under our hats and headgear. Enough! We demand our hair be visible!
This is often the case with helmets in games as things are often times forced to crop each individual hairstyle for each individual helmet to avoid clipping issues. The lazy way out is just to disable the hair and pretend like the helmet is covering it all up.
Helmets that cover the majority of the head make sense. What I’m referencing is headgear that leaves enough room for hair to actually hang down. For example the pirate hats you get from island expeditions.
They could implement a default long hair that shows up under certain hats and headgear if your hairstyle is long. The same with a likewise short hairstyle getting a short hairstyle under the headgear.
I am well aware of what you meant. And that still doesn’t change the fact that clipping would occur with many helmets. Yes, they could have a default hairstyle that goes along with helmets that make sense, but thats still extra work. this is blizzard we are talking about 
They should just accept the clipping TBH. Some clipping looks way better than random baldness, specially for females.
Did someone help you type that up?
The people. The people demand it!
Sure.
You forgot “the people” in your other thread, though.
I’ve always thought of it more like tucking the hair up under the helm, but I greatly prefer helms that do not obviate the hairstyle. Case in point…
