I shampoo my hair, to get all the build up out, then use a deep conditioner (20 minutes max). I towel dry my hair to get the excess moisture and braid into 4 sections. While still damp I add a little kemi oyl to a section and gently blowdry (combing hair with wide tooth comb as I follow with the blowdryer, 2 handed method), and rebraid, then I move on to the next section and repeat. When everything is dry, I unbraid one section and comb through with a medium tooth comb and then rattail comb, which isn't hard if I blow dried correctly. Then section off that section and flat iron each part with my Chi. Unbraid another section and repeat.
ETA: If a section is tangled, I add a lil more kemi oyl and detangle throughly. Try not to use too much though or you get flat, limp hair.
