What is a one-sentence summary of the following article?
Cleanse your hair with your normal shampoo and rinse it thoroughly, then saturate your hair with conditioner. While you have the conditioner in your hair, detangle it with a wide-tooth comb. Once you’ve combed it out, rinse away the conditioner with cool water.  The cool water will help seal your hair’s cuticles, making it look shiny. Once you get out of the shower, use a soft microfiber towel or an old T-shirt to gently squeeze away excess moisture. Continue squeezing and blotting your hair until it’s just damp, not soaking wet. Do not rub your hair too vigorously, as this can lead to breakage. Starting at the front of your head, take a small section of your hair and wrap it around your head just above your ears. When you get to the end of the strand, use a bobby pin to secure the section in place. Once the first section is pinned, take the next section from the same side and wrap it around your head as well. Pin it place, then continue for each section all the way to the back of your head. Then, start again at the front on the opposite side of your head and wrap the rest of your hair in sections.  By wrapping your hair, it will dry with a gentle curve, but it should look smooth and straight once you take it down. Make sure you’re wrapping your hair all in the same direction. It can take several hours for your hair to air-dry, especially when it’s wrapped tightly in this way. This is a great method for straightening your hair while you sleep if you like to wash your hair overnight. Once your hair is dry, remove the pins that hold the sections in place, then use your fingers to smooth out your hair and enjoy your straight style!

Summary:
Wash and condition your hair. Blot your hair with a microfiber towel. Wrap a section of your hair around your head and pin it in place. Continue wrapping your hair all the way around your head. Leave your hair to dry overnight, then style it with your fingers.
