To curl your hair without curling rods, you can try a few simple methods. First, try using a curling wand or a straightener. Wrap a small section of hair around the barrel or plates and hold for a few seconds before releasing. Another option is to braid your hair before going to bed. In the morning, undo the braids to reveal loose waves. You can also twist small sections of hair and secure them with bobby pins. Leave them in for a couple of hours, then remove for natural-looking curls. If time allows, try the sock bun method. Dampen your hair, gather it into a high ponytail, and wrap the ends around a rolled-up sock. Sleep with it overnight or wait for a few hours before opening the bun for soft curls. Be sure to use heat protectant and hairspray to hold your curls in place.
