Is there a way to make the heads look and stay upward?

Hi hi's. I need some help or advice on this little problem. I have two DC MSD dolls, a Ray and Loby, and both can't look upwards due to perhaps the O ring in their heads. If there a way I could possibly get around this? Sueding? Modding? Or what? They can look up, but they can't hold it, they basically snap back down once you release your hand. :/

If anyone needs a piccu to post what the inside of the head looks like let me know.

I really want them to be able to look up and stay up. >__<

FYI there's 4 corner bumps that holds the O hook in place.

To twigling:
Can you provide a picture or diagram to me to understand on what to do in the interiors? I'm more of a visuals person. Sorry.

 

Thanks a lot. I'll try out the sueding first as you said.

BTW what materials and procedure would be good to cut the resin and such just in case?

 

Thanks a lot for the info.

 

You kinda lost me, but I think I got the jist of what you said, at least for latter 2/3rds of the second part.

But looking at the head and the interaction with the neck, I'm seeing the string is hitting the back of the neck and can't follow through 'cause the string is being 'bented' and more tension is created thus might 'cause the prevention of look upward? (There's also a small gap that's created in the frontal area between the neck and chin, but I can probably just suede that.)

I might have to end up doing the mod twigling mentioned, if the sueding doesn't work, but possibly change it to kinda like how my AODs' necks are, they have no problem at all looking upward. (I just checked their necks right now, gen 1+2, lmao.)
FYI, the hole for the neck is just a straight lined hole with no angles or such unlike my AODs.

Also, again looking at my AODs vs my DCs, would one of the contributions to this problem might be the string itself? o__O??? Their string that connects to the head seems to be a lot tighter then the AODs when I first got any of them, AOD or DC.
(So possibly I have to do a mod/suede and a restringing?)

 

I'll try yours first since I'm like pulling the string atm, and applying pressure on the head with my hand near the magnets while doing the stance and it seems to show promise. o-o

UPDATE: Looking at the shape and how high the O ring it. The adding a stick to it might not work because of a) the shape inside is a bit steep to allow anything to be held to its sides and b) the tip of the O ring is very close to where the cut off is so close, I don't have a lot of space to play around with if at all. ._____.;;;;

To thothep:

Please supply when you do. I'm still open to many ways on how I can fix this.

 

Problem fixed now! !

Solution: Remember the gap and possible solution I mentioned?

I hijacked my mom's hot/cold dual glue gun after trying a couple non-mod suggestions, applied a bit of a thick layer to where that gap was being created(which is technically the bottom frontal area), it worked and added more pose-abilty than just looking upward and before!

Thanks for all the suggestions guys.

BTW, here's some photos of it:



I played around with the sueding since there's some side poses where it's 'weak' to hold, I just added the glue to the sides and it also worked. I didn't suede the back since it got 'ripped off' easily from my primary test when I tried moving the head around.
