Step 1 : Introduction to the question "What hairstyle was successfully patented in the 1970s?"
...When Frank Smith and his son Donald sought a solution for Frank’s baldness, they discovered that by growing his hair longer on one side and combing it over the top, they could create the illusion of a fuller head of hair. This clever technique led them to file a patent—US4022227A—which was granted in 1977, complete with diagrams illustrating how to achieve the look. The patent outlined instructions for sectioning and arranging hair to disguise bald spots, making the comb-over both a practical solution and a quirky piece of hair trivia.
