I had similar with a doll I got for reborning...the wig will not budge, no matter what I try (acetone included), So I have given it up as a bad job.
I also dicovered that my doll had a hole in her head anyway, so I would have had to re-wig. Shes for sale again now as I cant be bothered trying anymore!
I suppose you could try immersing the head in boiling water to try to soften the gle? But then it may damage the paintwork though...
Sorry, not much help am I??
