Ceramic flat irons produce gentle, far infrared ionic heat that won't destroy your hair and can help repair damaged follicles. Our professional salon ceramic irons come from the top industry brands. For long/thick hair, try 1 1/2", 1 3/4", 2" flat irons & up; short, medium & fine hair are suited to 3/4", 1" or 1 1/4" hair straighteners. Use high heat settings only for the coarsest, curliest or ethnic hair; style damaged, chemically treated or fine hair at low heat (under 300 F)
