Wigs are suitable for absolutely everyone, whether you've got a ton of hair, or no hair at all. They neatly skirt round the problems of colour-matching and weight, so you can do things with a wig that would be difficult on a real head of hair. You can also do things to it that you wouldn't dare do to hair - glue is your friend here.
They're also a perfect solution for anyone who has to look normal for work.

Making fake hair wigs is pretty straightforward. It can be summed up thusly: get hold of a wig, attach things to it in the same way you'd attach things to real hair (usually plaiting, or latch-hooking through the wig cap), and then wear it.
There are a couple of differences, obviously - since it's not real hair, you don't have to be quite so careful with heat and glue. You also don't have to try to hide the base hair so much, because you can just buy a wig in the colour you want and work with that. There's no obligation to plait to the end of the wig's hair, as there is with double-ended dreads on real hair - just braid enough to attach whatever you're attaching, then snip off the excess.

You might also find it very helpful to buy a cheap styrofoam/polystyrene wig head to skewer your wig onto - it's much easier to work on a wig on a stand that it is to work on a wig that's just flopping about loose.

In case you've never had a look at a wig, they usually consist of wefts of hair stitched in rows onto a base. The wefts tend to be quite spaced out at the back, and then the wefts get closer together as you get closer to the crown. The base may be a complete cap made of mesh, or may be a load of strips of lace strung together, with wefts stitched onto the lace. The mesh base wigs are easier to do extensions on, because you can stitch extra wefts on the mesh base if you need to. If you plait dreads, braids etc into the wefts on a wig, it can expose the mesh cap underneath - this is where you'd need to stitch extra wefts onto the wig cap, or, pull extra loose hair through the holes in the mesh with a latch-hook tool.

It's usually a good idea to spend some time tidying and sprucing up the fringe/bangs on a wig, after you've added extensions to it. This is often the giveaway to a cheap wig - one that has a very nylon-y looking fringe, or that's too long, or all one colour. You can glue little bits of weft in a contrasting colours between the layers on the fringe, or, just glue in little bits of loose hair - that'll make it match up with other colours on the wig a bit better. A pointy fringe, or one that's been swept sideways, will often look an awful lot better than the standard 'rolled bangs' that most wigs come with.

And that's pretty much all I have to say abut wigs. Worth the wait, huh? [fx: tumbleweed].
