Do not continue this process with soaking wet hair. Plaited hair takes longer to dry, and the curls will not form if your hair is still wet the next morning. Optionally, you can apply hair oil to keep your hair shiny and healthy.
Two thick plaits create a wavy effect. Smaller, tighter braids will create more defined waves.
Do not brush your hair. This will just make your hair frizzy and ruin the effect.
Section your hair into several parts. Begin a pigtail with each one. Halfway down each pigtail, separate it into two lengths of hair. Wrap the two lengths of hair around the sock or ribbon, in an over-under helix pattern. Apply hairspray and leave in overnight.
You can even wrap the hair around your finger, then secure with bobby pins before pulling your finger out. Take care not to poke yourself.
