Why does this happen to some textures and not others? Why is it only ever head textures? How come resaving from Photoshop corrects it?

It's down to the answer I gave at the beginning of the thread, where I pointed out that the diffuse colour map is sometimes used for other purposes too, which can cause the map to 'inherit' the wrong gamma. I gave the example of the map being used for the bump channel too, but it could just as easily be used for the specular and transparency channels, with the same result.

In the example texture you have since posted, it contains the transparency map for the eyelashes, and when used for that purpose the gamma is properly set to 1.0. Each texture map can only have one gamma setting applied, thoug, so when it used for two purposes one of them will be wrong (as i previously said). EZSkin resets the gamma in those cases, so that the gamma for the diffuse channel is correct and that of the other channel is wrong instead.

Resaving the texture with a new name makes it a different texture map, so it doesn't inherit the bump/specular/transparency setting of the previous map. You can now use one map with a gamma of 1.0 for the transparency, and the other with a gamma of 2.2 for the colour.
