I want a japanese perm, but im worried about the damages it will do to my hair. any suggestions/advice?

I straighten my hair daily, and my hair is about a little longer than sholder length, and always curls into my face at the end, and curls up by the end of the day, how do i stop this? I want a japanese perm, but im worried about the damages it will do to my hair. any suggestions/advice?
I use a Joico Heat Protector/Straightening palm the night before school when I take a shower and my hair is wet. I apply that on my hair and then blow dry my hair (so no frizz and crap) and then when I straighten in the morning, my hair is shiny, frizz free, and straight. I walk to school (20 - 30 min. walk) and I usually put my hood up so the wind doesnt **** up my hair and my hair is fine when i get to school. So yeah.
