I am almost shure my hair is highly porous (I bleached it a lot, it dries fast and it behaves in humudity like high porosity hair), but according the float test my hair isn't porous. I think the test is not that accurate. And what's more: there are also low porosity curlies that like prote´n, and high porosity curlies that don't like it. So I think you have to give prote´n a try to know if you like it. In most cases, highly damaged hair is also highly porous.
I think the best thing that you can do, if you want to go back to curly hair, is take really good care of it. Hair that is once damaged, can not be reapaired. You can take good care of your damaged hair and let it look somewhat better, but you probably have to grow the damaged hair out. If you continue to straighten your hair, it probably is never going to change like the situation how it now is.
So, I suggest that if you really want to wear it curly, you have to get rid of your dead ends en take really good care of your hair. So, no or little heat, no or little sulfates, no or little chemical treatments and lots of conditioner (satin pillowcase optional) etc.
Good luck girl!
