Chi uses Infra red heat if thats what you're talking about. Chi is seriously excellent! So most likely the one you're talking about is Chi, since a lot of their products say Infra on it. Is it black and has like a gold plating? The only reason I recommend Chi is because it gets hot within seconds and hot enough to straighten the hair and 'seal' the cuticles. Also, the standard Chi doesn't get too hot so that it burns your hair. It stays within a good range and its smooth! Trust me, I've bought and tried lots of brands and Chi works well on any hair. Plus the plate doesn't pull your hair like some do. Chi comes in so many different varieties and versions... Plus they have oil that doesn't wiegh down and smooths, shampoo, conditioner, and other products!
