The Beauty Updates You Can Expect on "That '90s Show"

Aside from the '90s Wisconsin yearbooks, the other most obvious place the hair and makeup teams got their inspiration for the kids was their parents. Specifically, in the instance of Leia (Callie Haverda), Donna and Eric's daughter, and Jay (Mace Coronel), Kelso and Jackie's son.

Similar to his dad, Jay has long, flowing '90s boy-band hair, because "Kelso always had hip hair," says Pollino-Rodman. Meanwhile, Leia's bob hairstyle is very simple, similar to Donna's in the '70s. "She is not as hip as the people that she meets in Wisconsin," she adds.
