Complex hair question.?

Okkaayy, i used to straighten my hair everyday with a pretty good straightener (Infiniti. $100), i used all kinds of conditioning products and my hair did not appear or seem any weaker or damaged at all. Then i got a perm (what was i thinking?) and yeah i did get some damaged hair along my front and back hairlines. After i got the perm, i did straighten my hair like 2x, but i stopped because i didn't want to damage it. It's been over 4 months since i got the perm and i really miss my straight hair, although some days i would like to wear it curly just to save time. Sooo... i want to start straightening it maybe once a week. opinion: in relation to damaging hair: should i straighten it once a week? or will all my hair fall out? ;) thanks. i know it's a long and weird question. do your best. thanks thanks thanks.
