1. Blow-Dry: In order to achieve extra length, you can blow-dry hair before styling. You don't have to make it completely straight, but it is more important to stretch out your length. Once hair is completely dry, you can add ringlets with a curling iron. Remember to use a heat-protecting spray formulated for curly hair like Ghd Heat Protect Spray ($21.59).
2. Roller-Set: If you're more low-maintenance, you can roller-set your natural hair while wet. Apply a setting lotion like Evo Liquid Rollers Curl Balm ($25.61) to dripping wet strands that are fully detangled. Then, taking small sections, you can roll using perm rods, Curl formers, or flexi rods. To keep ends from frizzing, try using end papers. If you're in a hurry, you can set under a hood dryer or air-dry overnight.
