Will straightening low porosity curly hair raise its porosity?

If I have naturally low porosity hair and I straighten it will that damage it just a little bit so that it will raise the porosity to about medium porosity.

Yes, but  it will also cause breakage. I suggest using a blow dryer to let your products penetrate. Try diffusing your hair instead. You should also use a heated cap or blow dryer during deep treatments.
