Day 13... FlexiRods on naturalhair. Flexirods are commonly used to make more defined, looser curls. Essentially you wrap you hair around the round which bends so that the rods can stay. There are different sizes of flexirods, the smaller the rod the tighter the curl, if the rod is big it create waves. Its better for me to use flexirods when my hair is freshly washed and with little oil in it. I also let me air dry which can take 3 to 4 hours, however you can blow dry your hair to speed the process along. There is an example of how to do flexirods down below by the YouTuber KaiRox who has a lovely head of hair.
