Hi Poser peeps! 

I need your help with the above item, which came with The Girl 4 over at DAZ. I just dusted her off tonight and loaded the hair, only to discover. much to my chagrin, that it doesn't have any really good morphs for, say, draping the ponytail over a shoulder or blowing in the wind. Do any of you know where I could find morphs for it, either free or cheap? Thanks in advance!

Here she is with the original hair. She has Dream9Studios' Nicola 3 textures (Superfly, which are available in Freestuff).

Moi, personnellement j'utiliserai la morphbrush

As Vince said, you could use the morph brush, or try magnets. 

Or use another, such as OOT's Zoey, which has The Girl morph

I'm writing this because I gave up with TG's hair long ago, as I have never been completely at ease with the magnets and the morph brush (my main use is to correct poke-thrus')

Wow, Y-Phil, she is beautiful! Whose body texture is that? I'm with you on the magnets/morph brush, although I wouldn't mind futzing around with the latter to create head/body shapes. 

I'd also like to know whose head morph that is because I'm not a fan of the default G4 head morph, which I think is too round/chubby looking for my liking.

In fact, this one is a Sasha-16, morphed to mimic some young sporty woman I've found on the net, with P3D's Aelita morphology deactivated and The Girl part of Sahsa loaded and active for the head.
So, I restart from the default TG4, from Daz, and loaded the morphs++, the Elite morphs  (<- not sure it's useful) and the head settings presented here:

Poser displays a message but loads it anyway:

The skin texture I've used is Seven's Arianna passed through EZSkin
Her eyes are doctor Jo's Veronica green eyes.
The hair is of course using Ghostship's Hair shading system

Hope this helps 😁

Thank you sooo much, Y-Phil! I'm in luck as I do have the Zoey hair :)

I don't think any hair has all the morphs I need, I almost always end up adding more using the morph brush. It's worth playing around with, I think hair is relatively forgiving for that.
