Professional hair brush, round ceramic, straightening.? - hair straightening brush

My hair stylist told me the other day with a round brush, ceramic type, which I use a 3-inch, I think. I was wondering if anyone knows what is the size of more than just the hair under Surls. If 4 or 4.5? perhaps even a brand that you know the great works, watch BC almost flat ironed my hair!
