Take the longer strand that should be on the doll's right side, behind the ear, wrap it around the pony tail. Then, using a toothpick or something like that, lift a bit of the rubber band and tuck the end in. It's tricky.
For the curl, I believe people use a human setting gel, a small piece of tissue, and a very thin permanent curling rod. Wrap it up in the tissue (those found in human perm kits work, but even a piece cut from some white gift wrapping paper will do), after applying some gel, roll around the perm rod, and let set. When dry (probably a day or so), carefully unwrap, remove tissue, and comb into place if necessary.
Oh, forgot to say, you'd put another small band just above where the curl will start before all this. Then, you can tie a ribbon bow to finish.
I believe this is how it used to be shown on Krista's doll repair site, but I think she's removed her tutorials.
