Despite these downsides, the HSI Professional comes with plenty of positives, including extras not often found with other hair straighteners. Along with the straightener, you'll receive a carrying case, a heat-resistant glove for easier hair styling, a style guide, and a travel-size argan oil leave-in hair treatment serum to smooth and protect your hair. This is more than most high-end hair straighteners come with, all for a fraction of the price.
The plates in this techy tool house an internal microchip that constantly measures and maintains an even temperature. With no random hot or cold spots, you'll get smoother, straighter, strands in fewer passes. (Spoiler alert: Fewer passes equal less damage). Adjustable temperature settings — from 260 to 410 degrees — make this ideal for any and every hair texture.
