Synthetic too shiny! Help

I'm new to doing extensions. I bought a weft of "futura" kanekalon that matched the shade of my natural hair. (Futura feels more like human hair and you can curl it too.) I was planning on sewing strands onto clips to add length around my face because my hair is short. I noticed that my only problem is that the hair is way too shiny and I couldn't match it even by using shine spray on my own hair. Is there any way to dull the shine on synthetic hair? It looks too fake and I can't return it and don't want to waste my money. 

Some synth gets less shiny with washing...
