there is a slight possibility that you have too much protein in your hair. that is usually the straw-like texture. so, try a dt with heat and see if that helps. make sure the dt does not have protein. if it does help, then i'd do as many dts with heat as you can over the next few days.
if it doesn't help, then i'm seconding the thought that you fried your hair.

good luck!
