Protein and Fine hair(questions)

I have fine hair which I read needs protein and I read about the LVPNG and I want to try it. How do I know if im protein sensative? I tried the suave coconut which I think has protein in it and my hair felt very dry but thats probably because it is loaded with humectants and the air in my area has low humidity so it may have back fired. Does the LVPNG have any cones? Does the rest of the LVP line have cones just in case my hair cant take protein?
