When we say we want Bella Hadid's body, know that we're referring to the va-va-volume she served on the night of her bae The Weeknd's birthday night. Part of Bella's luscious, voluminous waves might have been borrowed (clip-in extensions are magic), but the rest of the shiny waviness you witnessed are courtesy of flat hair fighters OUAI Wave Spray and Volumizing Hair Spray. The best part? Half-up hair, when secured tightly, has an instant face slimming effect. For sexy, half-up waves like the supermodel's, scroll down for Jen Atkin's step-by-step breakdown.

  1. Attach clip-in extensions
  2. Prep with OUAI Wave Spray
  3. Dry with the Dyson Supersonic Hair Dryer and Diffuser attachment on medium heat and low speed
  4. Enhance natural waves with the Kristin Ess 3-In-One Flat Iron
  5. Apply Tancho Stick to roots for a frizz-free finish
