I think this really depends on the specific product. A lot of face/body creams have lots of parabens, alcohol, cones, paraffin, sometimes way worse things (for hair) like strong acids.
I don't think they would do much for hair, besides weigh it down, but you could always do a 'patch test' of sorts and just try it on a small amount of your hair and see how it fares.
I think for heat protection you really just need a good heat protectant spray, I'm not sure if you are cone-free or not but tresemme heat defence spray is highly rated. I don't think a face cream would provide any protection whatsoever, sorry.
