Trouble with Racemenu face import/export

[Alexhia]

I'm very new to modding and I'm trying to create a Follower but I'm having several issues. I also have some questions.

1- I downloaded KS Hairdos SSE and several other mods to change my character appearance. The issue appear when I export a head with Racemenu sculpt option and then try to import it on a fresh character. At least two o the name strings are red, and I know it means texture is missing, but I can't understand why.

I tried removing all the mods, but the vanilla hair gives me even more strings of error (up to 4). Here is a screen (I was trying to import my modded head): Click Here

2- I know you can't directly import your modded character into creation kit since they will look vannilla. To import the head I found This Tutorial on Reddit and This tutorial on Wiki Nexus. I was wondering if this is the correct process, as I said I'm super new and just going around the internet trying to find tutorials and I also have zero competence in modding in general or programming ecc.

If anybody has any tips, tuorial ecc, I'll gladly accept the help.

Thanks for your time, now I'll list down below my mods.
