Marge Simpson's iconic blue beehive is not her natural hair color; it is the result of her consistently dyeing it. This distinctive hue has become synonymous with her character over the years.
The Truth Behind the Blue Dye
The reason for Marge's blue hair was revealed by her husband, Homer Simpson, in the episode "Secrets of a Successful Marriage". He disclosed that Marge has been dyeing her hair for a significant period. Her natural hair color, since she was around seventeen years old, has been gray. To achieve and maintain her famous look, she uses a product known specifically as blue dye #56.
A Consistent Style Choice Since Childhood
While her adult hair color is maintained through dye, Marge's connection to blue hair dates back much further. In the episode "Fear of Flying", flashbacks to Marge's childhood show her already having blue hair. This indicates that the choice of blue for her hair has been a long-standing personal preference and a key part of her identity, perhaps something she has deliberately chosen and maintained since a very young age.
