I'm not sure if you'll want to hear from me, as our hair types are quite different. But i'll answer anyways!
Before I straighten my hair, I wash, PT and then DT all the day before, simply because it would be too much to do it all in one day. The next day, I check my hair to see how dry it is. I like to blow dry my hair when it's about 20% damp, so I'll spritz it with a bit of water and avj before blow drying. I section my hair into four parts, and apply heat protectant as I blow dry (Fantasia IC heat protectant and CHI silk infusion). Before I flat iron, I apply a bit more CHI silk infusion, and I flat iron at about 375 degrees.
