Here is my night routine for my hair when I have it styled in two strand twists. This process keeps the twists stretched and keeps the relaxed ends from being disheveled.
All you will need is a couple of bobby pins and your satin/silk scarf.
Next, wrap the twists at the back of your head towards the right side of your head. Secure that section with a bobby pin.
Now, gather the twists on the right side of your head and wrap it towards the left side of your head.
Here is the front view.
Lastly, tie on your scarf to help keep the twists from moving out of place.
