Here's how you can achieve Nicki's playful and wavy locks:
1. Dampen Hair. You can do this in the shower or with a spray bottle of water.
2. Section your hair into four parts ( two in the back, two in the front )
3. Braid each section.
4. Tie off and then go to sleep. You will want to start this process at night so hair has ample drying time.
When you wake up apply mousse or hairspray and voila, you will achieve Nicki's playful locks!
