In the 1960s, TCU adopted a purple and white helmet with a large "TCU" logo in the center. This design remained largely unchanged for several decades, becoming one of the most recognizable in college football. In the 1990s, TCU began experimenting with different helmet designs, including a black helmet with a white "TCU" logo. This design was short-lived, and the team eventually returned to its traditional purple and white look.

In recent years, TCU has made several updates to its helmet design, incorporating new technology and materials to improve player safety. The team has also experimented with different helmet graphics and decals, including a horned frog logo and the number "2" to represent the program's two national championships.

The TCU Horned Frogs football helmet is a symbol of the team's rich history and tradition. It has evolved over the years to reflect the changing landscape of the sport, while still maintaining its iconic purple and white colors.
