Wig gel/wax?

Hi. Are there possibly any other options for wig wax or some type of styling gel except the ones volks sells and azone? I was thinking maybe the stuff they use for cosplay wigs but im very unsure and dont wanna ruin my doll if her hair touches her, thanks in advance.

I’ve regularly used wig spray made for synthetic/cosplay wigs on dolls, I haven’t used wax but I don’t see why it would be different as long as it’s made for for synthetic hair and not real hair.

To be honest I use got 2 be hairgel and hairspray on my dolls. (Dollfie dream and others like Barbie,Bratz etc.) 
Dollfie Dream wigs (Smart Doll Wigs) are all made from the same fibre as cosplay wigs and as for now I never had any problem. Recently I also had to use clear drying non toxic water based glue to fix a doll wig because the layers were cut too short and it also works fine.
