You will have done this when you were little, but maybe you’ve forgotten about this super neat trick to get mermaid waves over night.
Wash or dampen your hair then braid it however you like. For loose waves, just a couple of braids. But for a more crimped look, try lots of braids. Then go to bed, wake up the next morning, take out your braids and enjoy your new mermaid look.
If you haven’t got 12 hours, just braid your hair and then run over the braids with a straightner!
