Try Rag Curls. When I want a change, I do this before bed and I wake up with a head full of curls that won't quit for days. Cut a pillow case into strips approx 3 inches long and 2 inches wide. Make about 20 strips. Starting with dry hair, take a section of hair and spritz with water, or better yet, a leave in spray conditioner. Wrap the bottom of the hair section around the middle of the strip and roll under and up to the top of your head. Tie the ends of the strip around the hair roll in a knot. Don't worry, it will come out easily in the morning. Do your whole head. Not only will you have fabulous curls in the morning but you'll look cute as hell in your jammies!
Here are a few tips...Do NOT use a brush on curls. You will end up with poodle head. I style my curls with either a wide tooth comb or my fingers. The smaller the hair section, the smaller the curl. The tighter the roll, the tighter the curl. For loose curls, just roll the hair up gently and loosely. Do NOT spritz with holding hair spray before rolling hair sections. Your curls should last a few days if you don't get them wet. And if you hate the curly look, just wet them down. I love doing this because it makes me feel different and kind of sassy and sexy! Have fun!
