P.S.: just a little workflow, to check out how it works on your side, and so we have (hopefully) quickly something working for you.
The files are here: https://www.amazon.com/clouddrive/share/lO_Kb9nlYtgpscczpfjNXiwoYDzgxDe08lYgfGTbQBE?ref_=cd_share_link_copy_flash
1
In your scene-one, where you have the Hair-object in the way you want to have it: “Cache” the result and save it to your project folder (or any place in your network if needed)
2
Clear the “Link”, so the Hair representation is “de-tached”, which will result in the green little circles.
3
Copy the Hair-object into the scene-two, your target scene, and place an object into the “Link”.
4
Load the cache-file into the Hair-object, check if it shows any memory use. If it shows 0.0KB something is wrong)
5
If not already done or available, set up the Render-Settings so the Hair-Render is available!
6
Move the target object (the one in the link), the Hair-object should follow, and show no sign of influences of the movement—in terms of hair Dynamic. Here the cache content is the only information used to move each hair, but the complete Hair set up should follow. I hope that makes sense, and/or I got your target idea correctly.
