This is simply using hair ties to softly stretch your hair. To do this, first use your styling products to shampoo and condition your hair. Before it dries, part a section of your hair measuring roughly 2 x 2 inches, and twist or braid each section straight from the root until the ends.
Then, starting from the top of one of your twists or braids, tie a hair tie around your hair’s root and wrap more until the end. After this, let your hair dry before you remove the hair ties. Finally, separate your strands, then fluff them.
