I got this method from
www.hairoil.com hair guide/techniques and it has worked well for me.
I apply a leave-in (Lacio-Lacio) to wet/damp hair and I seal with a light coating of Vatika oil. My hair is already divided into 4 section (2 front & 2 back) b/c I poo and DC that way. Anyway, I pin up all the sections with clamps or Good Days hair pins making sure to tuck the ends of my hair under the section before pinning so that they don't dry out. Then I divide one of the sections into 2 sections- I pin one while I dry the other.
I set my blow dryer on a very low setting and I don't use attachments. I
hold the ends of my hair and protect it with my hand while I hold the hair taut- I don't pull hard- put I gently stretch the section of hair and pass the blowdryer over the hair. The dryer is about 4 to 6 inches away from the hair and its on low. I have a Tourmaline dryer. I dry the shaft about 95 % but only dry the ends about 85% then I go on my way or scarf/bonnet for the night.
If you are curling with an iron or flat ironing you need to dry all the way before using the irons.
I do all the sections like this until I've done my whole head. HTH
