I saw no one had replied to this, so I figured I'd help out.
Straightening for me can be a chore, that's why I dont do it often but when I do, I want to make sure it's nice to squash the 'natural hair cant get straight' haters I have in my life.
I think technique and product are key. I use a blowdryer with an attachment, Vidal Sassoon ionic and a tool science flat iron on 370. I think the more heat I use, the thinner my hair looks. I deep condition, shampoo and condition again. I have a spray mix of moisturizers which include shea butter, a little conditioner, olive oil, and coconut oil and water. It's more parts water. I spray while wet and massage it in. After I apply heat protectant, I blow dry in the downwards direction and relative to my part with my hair parted in two horizontally.
I apply a little more heat protectant after, for the flat iron's sake. I do two or three passes on small sections and then I wrap my hair in saran wrap. I sit under the the dry for 15 min and then unwrap. I can style and go or wrap it back up with my silk scarf for extra smoothness.
It works for me everytime
