Making Foil Armarture for Sculpting the head
Method 1 - for a small head
I use a big lump of wood with a hole drilled into it, to use as the base to pop the head in and support it while I'm sculpting. Start off with a big long screw - I'm guessing about 5" long and I wrap tinfoil around it over the screw and keep adding more tinfoil till it's about the size of a large egg. It helps if you have a reborn head sculpt to compare with. 
I try to get the shape as near to the finished shape of the skull by pressing in down onto the worksurface into a tight ball, refining the shape as I go. Keep scrunching up more tinfoil and adding it to the shape your creating. Wrap a long length of foil over the screw to thicken it up for a neck but leave enough of the screw out so you can place it into the hole in the wooden base support. I add more tinfoil around the screw to make the neck, but once the sculpt is finished I usually unscrew the screw from the sculpt.
Method 2 for a full size head
I start with a long piece of tinfoil and I sort of scrunch it up into a long sausage shape and keep folding it over to get a sausage sized shape. To this I add a ball of tinfoil which I form over half the sausage shape, so now I have a head and neck, now I add a few sheets of tinfoil over that so the head and neck are now together. Keep loosly scunching up the tinfoil and adding it to build up the shape, add a full sheet over it all if it's falling apart and keep pressing it tightly together.
If you can get the shape correct at this time your more likely to produce an accurate sculpt. With this method I use a block of wood with a long nail screwed all the way though it and I screw the head onto the screw by just turning it round and round on the screw until it's tight. I bake it in the oven on the block of wood and it's never come to any harm.
Some people use Mannequin head stands, the type used for hairdressing to hold there sculpt instead of the block of wood, if your using one of these, you will need to start forming the sculpt over the stand instead of over the sausage shaped tinfoil.
This is one that I made that was all wrong. 
Because the foil was all wrong I had to add loads of clay on top of the head and at the back of the head, this ended up too thick and the head all cracked. You want to start with a shape that allows you to add the clay quite evenly over it then there's less chance of it cracking.
It helps if you place the sculpt infront of the reborn head to compare shape. This one was nearly there 
but it needed a bit more adding before it was right.
Now this one was the right shape. 
Once I am happy with the shape of the head I start adding the eye sockets by pressing the tinfoil in, I use spoons and the end of a knife and allsorts to put the foil in to get it the right shape and also by scraping the foil out.
I create the nose and mouth area by adding more foil to the front. If the tinfoil bits that your adding keep falling off you can tape them on with masking tape then add more tinfoil over the top, but keep pressing the tinfoil down so it's nice and solid. It took me about 3 hours to make this form.
One thing to remember is that the eyes are half way down the face - I find this bit the hardest, I'm always tempted to place them higher up. but they should be half way down the head. When your happy with the finished shape cover the whole head with masking tape, but try and end up with the end peice of masking tape at the front of the face so it will be covered with clay first and there's no chance of it coming undone.
You can still press the head in and refine the shape at this stage if your not happy with it.
I hope this makes sense if not let me now and I will try and explain myself better
