Using flat iron on my natural wig

[Kayla1995]

Hi everyone! I wonder if I can use a flat iron hair straightener on my natural hair wig from Indique. Can't really find this information for my particular model from the manufacturer. I want to straighten it a bit with a steam iron from my sister (the one that produces steam between plates, like these), she says it's much less damaging than an ordinary iron, but I'm still not sure.
