According to HuffPost, Lucille Ball's natural hair color was actually brown. She changed her hair color to platinum blond for the first time when she entered the entertainment industry. Those bright blond locks made her stand out and helped her book a couple of minor roles in movies for Metro-Goldwyn-Mayer. By the 1950s, MGM asked her to change her hair to a heart stopping, eye-catching red. She agreed, and her most recognizable look was born. 

The bright red of Lucille Ball's hair was her defining feature on the legendary sitcom, I Love Lucy. Because she was a natural brunette, her hair required specific care to maintain that beautiful color. According to PopSugar, Ball's hair stylist revealed the secret to how they got that recognizable red. Apparently, her hair was not just dyed red, it was more of a "golden-apricot" color, and the red was achieved by using a henna rinse as well. Even after her most famous show went off the air, Lucille Ball still rocked her iconic red hair.
