Before the season started, and to coincide with the dark, ominous vibe of the show, Sanders had to bring down Sydney Park's golden highlights. "Because her character, even though she is striving for perfection in every aspect of her life, including her hair, we didn't want her to look like she's going to the salon all the time to get highlights," she said. "So even though her curls are on point, we had to make it darker. At first we used a temporary colour gloss so that she wouldn't lose the colour altogether in her real life, because she really loves those highlights. We did that a few times during the show. Then, we sprayed her hair with Illustrator, which is an alcohol-based makeup. I just painted that on with a paintbrush and it washes right out."
