You need to have washed and dried hair before you can start. Once your curls are ready, washing your hair will straighten them, and defeat the purpose. Just wash your hair a day before (or at least a few hours before) so that they are thoroughly dried up by the time you start working on them.
Take sections to work with
Ideally you should part your hair from the middle before gathering it all and placing it on the front to work with. Now take one section from one side of your hair and start twisting it.
Just hold a section of your hair and start twisting it around on itself until it all comes together. You don’t need to twist them around too tightly, just make sure there are no loose locks.
While you twist one section of your hair, add more sections to it and twist them all together, much like French braiding. The aim here is to twist one complete side together into one section.
Once you have twisted all the sections together, make sure you go all the way to the tip and then hold it tight for the next step.
Holding the tip of the twisted side you need to wrap it around itself into a bun of sorts. Don’t worry about the placement; you can set the bun behind your ear. Just make sure it’s not wrapped too tight.
Once the bun is set you need to tie it with a hair tie and secure it. Wrap the tie around the bun twice and make sure the tail of your twisted section is also tied up. This will prevent the twist from coming loose, especially while you sleep.
Now repeat this on the other side of your hair get a good night's sleep.
You can untie the buns when you wake up the next morning. Just inspect them to see whether they remained intact during the night.
Once you untie and unwind the buns, start separating your hair by running fingers through them. The sections you twisted together will be tangled with each other and need to be untangled.
Once you have separated the sections, just set your hair with your hands and enjoy the curls. You did it - overnight curls without using any heat!
-Make sure your hair are dry before you begin. If you twist wet hair into buns they won’t dry till the next day and your curls will be very weak.
-The tighter you tie the buns in the end the more pronounced your curls will be.
-Don’t wash or brush your hair after this process to keep the curls for longer.
