MH G2 Electrified Hair -what melts it? how to fix it

[Princess_Luvlee]

I remember back when G2 Electrified came out people were having trouble with the hair melting.  I'm just trying to help someone out who thrifted the Frankie with electronic components, seeing if anyone knows what can and can't be used on their cheap crimped hair.

I can't seem to find any info on the web anywhere even tho the community blew up  about it and deterred me from buying them new.

Any advice?
