Lawrence's character, Kate Dibiasky, spends most of the film begging everyone around her to take the aforementioned comet seriously. Her look, which includes red-velvet hair and micro bangs, is fierce and helps set her apart from DiCaprio as professor Dr. Randall Mindy. "I wanted to make sure they seemed like they were from two different worlds," Dehaney said.
In pre-production, Dehaney spent a lot of time testing out different kinds of bangs for the character. For a while, no one was quite sure who Dibiasky was and how her personality would translate through her look. After trying every kind of bang out there — a swooped-over bang, long bang, and no bang — Dehaney had the idea to try one more: short bangs, more popularly referred to as baby or micro bangs. Turns out, while she was cutting the wig, costume designer Susan Matheson sent Dehaney a reference photo of a hairstyle she liked; it just so happened that the exact reference photo she sent, unbeknownst to Dehaney at the time, matched exactly what she had cut. Sometimes cosmic alignments do work out in our favor.
Of course, getting to this finished result wasn't easy. It took 25 wigs, many of which were dyed a range of colors, including platinum and black, before Dehaney landed on the final look. When it came time to fit Lawrence for the wig, Dehaney suggested the actress take a stab at the hair — literally — offering her the chance to trim and shape any look she thought might fit her character. Eventually, the two moved onto another wig, the red one with micro bangs, and they immediately knew it as the one for Dibiasky.
