"We Had So Many Wigs!" — and Other Beauty Secrets From Impeachment: American Crime Story

Since the show is set in the '90s, the hair and makeup team wanted to stay true to the trends that were prevalent during the time period by sourcing and using products that were staples throughout the decade. According to Driscoll, one hair product that almost never lasted on set is the Paul Mitchell Flexible Style Sculpting Foam ($25).

"It's an affordable product, but it also just works," she said. "Over the season, people would try to use more modern-day products, but they didn't act the same."

On the makeup side of things, key makeup artist Karrieann Sillay connected with several beauty brands that were popular during the decade to source some of the same major products for the show. "MAC was huge in the '90s," she said. "The Spice Lip Pencil ($19) and all the muted browns and earth tones were huge back then. A lot of the shades are still prominent in the line, they've just been renamed, so we were able to connect and get a lot of those products."
