For my second attempt at rerooting, I had another look at the various rooting methods and decided to
use an anchor thread, adapting the 'Needle and Thread' technique described on the
Instead of upholstery thread I picked a rather thick but fluffy (loosely spun) type of thread (probably meant for embroidery), do make sure the thread is hard to break.
Cheap dental floss wire (without wax) also works great.
The length of the original spiral rooting pattern plus the parting line on a CG head is about 40-50cm (16-20in), so for a full reroot use some 60cm (24in) of thread: you want at least 10cm (4in) excess length.
If you just want to redo the parting line, about 15cm (6in) of thread will do.
I started by inserting two plugs of hair next to each other at the start of the pattern (over the righthand ear). I threaded the loop of the first plug through the loop of the second plug, then firmly tied one end of the thread to both loops of the two plugs of hair and pulled the knot into the head (I used two loops, one threaded through the other, so one keeps the other from getting pulled back into the head).
Then using a split wire needle, inserting the folded tip into a hole in the head and out of the neck hole, I picked up the thread, pulled it back until I had pulled a small loop out of the head, then I slid off the needle, inserted a plug of hair into the loop and pulled back the thread.
First the loop pulled back into the head, then the thread slid through the loop of the hair plug. I did not pull the new plug of hair tight yet.
Repeating the above, I inserted the second plug of hair after which I pulled the first plug tight.
The fluffy thread proved to offer some benefits: first of all once a plug gets pulled tight it tangles into the thread, locking it quite firmly. Secondly the thread won't slide through the tight end of the eye of the needle so you can avoid pulling a part of the thread with hairs tangled into it through the hole in the head.
I followed the original spiralling rooting pattern counter-clockwise.
Then I rooted the parting line from the back of the head towards the forehead in a saw-tooth pattern, rather than one row at a time.
Finally I used a pair of hair plugs inserted in a bald spot on the back of the head to tie the end of the thread to and pull it tight.
I did not take pictures of the procedure but hope the diagrams make the steps clear:
First insert two plugs of folded hair into the head, let each loop
stick out of the neck hole and thread one loop through the other.
Note: if you want to follow the original rooting pattern on a CG head, then better start near the right-hand ear as that is where the original pattern usually starts.

Insert the split wire needle into a hole in the head and make the tip come
out of the neck hole, then carefully widen the eye a bit and insert the
Slide at least 7.5cm (3 inch) of thread through the eye so the end of the thread won't disappear into the head during the next steps.
||Pull the needle back and pull a small loop of thread through the hole, then slide the needle off.|
Thread a plug of hair through the loop and pull the thread back
until the hair gets pulled into the head.|
Then pull the thread some more until it is tight again.
Gently pull the previously inserted plugs of hair to make sure the thread lies tightly against the inside of the head.
Repeat Steps 1 to 3 until the head is completely rooted.|
Then root the parting line from the back of the head towards the forehead in a saw-tooth pattern.
Finally pick a bald spot on the side of the head opposite to where the final plugs were inserted (the distance is needed to be able to pull the thread tight) use a needle to poke two small holes in the bald spot and insert two folded plugs of hair in the same way as in Step 0.
Tie the end of the thread to these loops of hair, cut off any excess thread and pull the knot into the head.

That's all !
