The original Chi 1-inch flat iron is best for people with straight or slightly wavy hair. For hair with a thicker wave or tight curl, the G2 ceramic and titanium model provides more straightening power. People with short hair should choose narrow irons, while wide models style longer hair faster.
People with color-treated or delicate hair should be cautious when using Chi flat irons. Overstock suggests preparing hair with one of Chi's color protectors or keratin mist products to minimize heat damage. Buyers with thin or treated hair should choose a Chi model with adjustable heat settings and use the lowest setting for safety.
