Okay. Short explenation how to get Sephiroth's hair to one piece.
Sephiroth's hair contains of three long ahirs divided into 5 parts. It gives you a total of 15 files for his hair.
The hairfiles are ranging from SAAP to SABF.
How to put them together?
1st hair is : SAAP-SAAT
2nd hair is : SAAV-SAAZ
3rd hair is : SAAB-SABF
If you're doing it in MS3D then, use Ultime to extract those files to .raw.
Begin with SAAP. Flip it vertically.
Take the next file. Flip it.
And so one files from SAAP to SAAT. You will get the first hair. Then do the same with the 2nd and 3rd. Now get them together pin them under his head and voila, completed (you might to need to rotate them a bit so the hair won't get inside his chest).
Great news for Sephiroth Patch fans!
I just took my time and did something like this.. I got Sephiroth to use cloud weaponds (looks odd) and his Ultimate Weapon look like masamune. Now you really should see Sephiroth with a "Buster Sword" holding like a Masamune. Ugh!! 
Oh yeah. Bout weapons. I also made something like a color range - all weapons for him are Masamunes. But the better the weapon it is more mettalic and shiny like the real Masamune.. The weaker the more rusty/dark it gets.. What do you think about that?
For all girls out there - Sephiroth look cool when you combine him, change torso to Last Sephiroth Torso, make some adjustments ane he look's way sexy in his outfit (no top)..
Next major change is that Sephiroth is Sephiroth everywere instead of Cloud (you take all Clouds files and replace them with Sephiroth files). This one is just a theory but it might work.
Wheeff... Enough is enough... End of update..
