It'll still work in Daz Studio, you have a couple of options.
1) Parent it to the head, and adjust the x/y/z scale to fit
2) Autofit using the Victoria 4 option.
As for how I managed to get it to work (tried it just now, I usually don't have problems with such things, I just autofit them.)
1) Grab this package (I'm assuming you did this already, just stating the obvious)
https://f95zone.to/threads/hr-159-victoria-4.12720/
2) Grab the Runtime folder from inside the .rar, drag it into whichever Library you usually put stuff in (My Library, My Daz 3D Library, etc.) and merge the Runtime folders so that the assets are placed properly.
Folder placement is very important here. If you drag the runtime folder contained within the .rar inside of the Runtime folder in your library, instead of dragging the Runtime folder inside of your My Library/My Daz 3D Library/Whatever folder and merge the folders, the paths will be off and the asset may not work.
3) Go into your Poser formats inside of your Content Library Tab, choose whichever library you dragged the folder to, and then look for Figures > Ali > Hair. HR 159 should be in there.
4) Take your mouse and grab the thumbnail and drag it into your viewport window while nothing in your scene is selected, and the hair should appear. You could also try to apply the hair to your figure directly, I'm just having you drag the hair into the viewport to make sure it works/was installed to the proper folder paths.
5) The hair should be currently selected (in the Scene tab and in your viewport). Right click on the hair and choose the 'Fit To' option, choose Victoria 4 as the 'fit' option and of course choose Linda as the 'target', and the hair should fit to your figure.
6) Alternatively, you could just parent the hair to Linda's head and use the x/y/z scale and translate options to position the hair on her head, IF you can't get autofit to work (say if you are trying to fit to G8 or G9 maybe/don't have the V4 autofit option for some reason), although Autofit should just work.
That's what I did. Texture options should be in Poser Formats > (the library you installed the hair to) > Pose > Ali > Hr-159. If such things are important to you, you could then apply the Iray Uber base shader to convert the Hair to Iray, otherwise you can leave it in 3Delight format...
Hope this helps!
