 When you getting ready to finish the attached piece and make a silicone mother mold will be of Hydrocal. A reliable suggested is to make a glove mold with all due respect, then keep looking and feeling dubious to sure the silicone is going to be flexible enough and hair after leaving the area of the neck,if you just being paranoid and ignorant about this,  is a glove mold a possible recipe for disaster.Run the parting line up the back of the neck over the hair, a ways down the forehead and then to the temple down the cheek and back to the chin and down the neck avoiding all the detail of the eye, nose, mouth etc.

Completely unnecessary. Just a slit from the back of the neck to half way up the hair bun thing, and it will just pull off the front, bit like a glove  Avoiding any parting line on the face and most of the hair altogether.The glove mold should work fine. Build up the area where you're going to cut it, so it's about half an inch thick or more, and use a zig-zag cut that will key the sides together. One thing you need to deal with, though, is air getting stuck in areas that will be pointing up when the mold is being filled, like the lobes of the ears and some hair details. You don't say what you're casting in this mold, but it will take some strategic rotation of the mold as it's being filled to get a good casting without voids.

Also, test that rubber on something made of the same material with the same coating on it, to make sure whatever it is doesn't inhibit the rubber from setting - platinum cure silicone is very particular that way.
