Solved: Small but recurring issue with Classic Long Straight Hair with dForce

I use the Classic Long Hair with dForce for Genesis 8 Females a lot, and I have this one recurring issue that I haven't been able to work around. If it's on a figure that is posed to look hard to the side, after simulating, the hair on that side will have a distinct section that flares outward. Any pose that involves a hard turn of the head seems to cause it. Any other pose, and the hair simulates as expected.

I have tried everything that I can think of. I think I've worked my way through all the shaping options that come with the product. I tried upping the gravity and air resistance simulation settings. I've tried everything from a memorized pose, and not. I've even tried primitives with static surfaces arranged around where the flare happens to try to divert or flatten it. The latter affects it - in fact I've gotten some interesting effects from arranging nested spheres there - but so far, no luck in accomplishing what I want, which is hair settling down flat like in every other pose. I'm guessing that there's some surface settings to try, but as you can see in these examples, the rest of the hair is about as straight and flat as hair gets.

Most of the time, I can work around it, but if you need to have something where that flare is - like a second figure - I cannot get that piece of hair to behave.

Attached are examples - with flare, on a pose in which the figure is looking to the side, and without flare, on a random pose that doesn't involve a hard turn of the head.

(I'm pretty much a newbie, so if this is a stupid question, or a question incorrectly asked, be gentle. :) )

What happens when you simulate to an ordinary posture and then turn the head using the posing/translate/shaping (?) tools? I'm a newbie too, so don't laugh too loud if that was a silly question.

Have you tried increasing the Stabilisation Time in Simulation Settings?

I'm embarrassed to report that I found the problem. There is a second figure in this scene, standing directly behind the girl, which was made invisible to the simulation. However, I must have overlooked making its eyelashes invisible. 

I have plenty of experience dealing with this hair getting caught on things like eyelashes and buttons on nearby figures otherwise made invisible, but it fooled me this time because it only was happening in this pose. Because I'd had this same problem previously with a looking-hard-to-one-side pose and this hair, in a circumstance when there was never a second figure or any other relevant object nearby, I jumped straight to conclusions. Don't know what was going on that other day, but it's "case closed" on today's issue. See attached.

contedesfees, there are no silly questions! (OK, there are, but that's not one, if you haven't tinkered with this hair or one like it.) For the record, the "PostSimulateMove" attachment here is an example of what happens if you simulate this hair and then change the pose. What I did was move the head back to face the front, after having simulated the hair for the looking-to-the-side shot. The hair is retaining the shape it had from the original simulation, which no longer matches where it is.

I'm really going to love getting to know DAZ Studio. (Yipes)
