If you want a new HSI flat iron in your hair routine, make sure to stop and consider some important factors first: temperature range, dual voltage, accessories, and price. I made sure to search for the brand’s best of the best out right now. If you want to find out what made it into today’s list considering these factors, go ahead and read along now!

I like wearing my hair natural, waves and frizz and everything in between. I still like to straighten my hair from time to time whenever I’m in the mood for something new and different from how my hair usually is. The thing is, on top of having wavy hair, my hair is dead thick. It’s one of the reasons I never grow my hair past my chest as it gets heavy with the length.

Part of having frizzy, thick, and wavy hair is the fact that not all flat irons work well to straighten and tame them. Thus I begin my search for efficient yet safe options. With my search, I stumbled upon one leading hair styling brand: HSI Professional.
