HSI Professional a company based out of the Miami area. They deliver salon-quality flat irons and other styling tools as well as hair care to consumers from 47+ countries all over the world.

I am a big fan of Jason Makki, a talented barber stylist based out of Dubai. He sometimes uses the HSI Professional brand of  Hair Straightener on his clients. However,  if you think that black is just too manly, it also comes in PINK.

In this article, we answer:

What are the 6 Standard features on every HSI Professional Hair Straightener Flat Iron?

  • Do any flat irons come with solid Ceramic or Titanium plates?
  • Which is better, Dial or Digital heat control?

Detailed Review of HSI Professional Flat Irons

The real reason why people really like this iron is it has tons of features and is battle-tested, but it also comes at an affordable price, with a satisfaction guarantee and a 1-year warranty.

In Review

The main differences between these HSI Professional Flat Irons are:

  1. temperature range
  2. Dial vs. Digital heat control
  3. More expensive models are solid Ceramic or Titanium plates and not just coated.

My recommendation :  if you can afford the digital heat control, buy it. Digitally controlled temperature settings on hair straighteners are more accurate and help you to use just the right amount of heat and not more.

So for fine or thin hair, choose the ones that start with the lower temperatures. Ceramic is better for fine or thin hair over the titanium model.
For Thick Hair, choose the Titanium model.
