Well I am sure their are many different ways people section their hair off to do it. As for me I just take my wet hair and do 2 school girl braids on each side and then I take about 4 inches of foil and wrap it around starting from the middile of the braid down to the end ( make sure foil covers the ends and all hair that will be touched by heat) then I take my hot curling iron and apply it where the foil is and go down the foil holding in place 5-7 seconds. Once you complete this keep the foil on until it cools. Oh by the way I used Dudley's pressing cream, I am sure you could use any pressing oil. Good luck!
