Michael Landon played Charles Ingalls on Little House on the Prairie. Not only that, he was the executive producer, director, and writer of the long-running series. Basically, he had to be on set every single day! There were some times when he had to stop filming because something went wrong. For instance, the time his hair turned a lovely shade of purple. When Michael was on the show Bonanza, his hair started graying prematurely. To combat this, he reportedly used Clairol Medium Ash Brown to dye it to his original color. He didn't like to go to the hair salon, so he would dye and cut his hair himself! Michael Landon's hair once turned purple on set Over the years, Michael continued to dye his hair this color.
