22 Facts About The Award-Winning Series

Female characters on "The Marvelous Mrs. Maisel" sport the carefully coiffed hairstyles that characterized that era. For stars Rachel Brosnahan and Marin Hinkle, who plays Midge's mom, Rose Weissman, there's a secret behind how they maintain those 'dos: they're wigs.

In fact, sharp-eyed viewers may have noticed that Midge's hair changed early in the first season. "We shortened the wig from the first couple of episodes of the show to make it more perky," said Jerry DeCarlo, the series' hair department head, in an interview with Refinery29. "She has a perky quality as a character, so we wanted the wig to match." According to DeCarlo, the show attempts to recreate the hairstyles from the time — back when women would typically have their hair washed and styled in a salon to maintain the same look. "Back then, you'd keep the same style for basically 10 years or beyond," DeCarlo added. "Women in that time didn't change their hair on a daily basis."

That, explained the series' key hairstylist, Kimberly Spiteri, is why the wig that Brosnahan wears for the role isn't just crucial for the character's signature look but is also illustrative of Midge's personality. "Part of her character is that she always has the same style that she's had since she was 12 years old," Spiteri told Allure. "She's evolved a little bit, but we haven't changed her too much."
