I have used the CC3 and some cc3 embeded hair style, exported clothed character fbx, I then imported the fbx into unreal engine 4.25+ and the mesh looks correct when dragged onto the veiwport and dropped into the scene, but when i run the game, the characters hair seems to be coming from between her legs, and movement is wild.
I'm not sure what i did wrong.

Not 100% sure, but on your 4th picture also check the box that says "Update skeleton as reference", see if that helps

For me it looks like your hair hasn't been skin weighted as hair in CC3 but as accessory parented to a wrong bone. (but I am not sure too)
In the CC3 Scene manager you have symbols beside every mesh , which symbol does your hair have?

Oh yeah, you're right.  Hair as accessory might be parented to the hip bone and not the head.
Jordanlaboon  -check to see what bone the hair accessory is attached to in CC3, it might very well be "Hip"...if so, you would want to change attachment to "Head"

I have the exact same problem, but I can't figure out how to fix this. This is how it looks in CC3 and how it looks inside the UE4.
Can anyone give some detailed help please?
