Justice was inspired to try this Dyson Airwrap Multi-Styler ($600) out for herself after seeing the tool's revolutionary effects on her sister's hair. "I would see her get ready for a night out and her hair would look like she got it professionally blow dried or something — it had some nice body and movement. I was like, 'How are you doing this?'" Justice jokes. The cult-favourite styler has been an essential in her beauty cabinet ever since.
