I'm guessing that a high number of people have tried this at some point in their lives, but this is for the ones who haven't! So here's all that you have to do...
- Wash your hair
- Put plats (braids if you're America) in your hair while it's damp. The bigger the plats, the bigger the waves.
- Tie string around the bottom of each of the plats. The string doesn't damage your hair like elastic bands would.
- In the morning simply pull the pieces of string from the ends of you hair. The string doesn't snag so don't worry about that!
- Carefully take out the plats and run your fingers through your hair and there you go!
You can always add some product to define the waves if you wish :)
