For 40 years, CHI has shaped the future of professional hair styling. Marking our Ruby Anniversary, this iconic 1” Hairstyling Iron celebrates a legacy built on innovation, performance, and trust. What began with award-winning ceramic technology has evolved into our patented CHI LAVA Advanced Technology—a powerful fusion of CHI Ceramic and Volcanic Lava. Like the ruby, a symbol of strength, passion, and longevity, this evolution delivers enduring performance with smooth glide, consistent heat, and healthier styling—honoring where we started and how far we’ve come.
