Excellent, Salon-Quality Iron

The HSI Professional provides one of the top straightening experiences available today. With a combination of ceramic and tourmaline plates, a heat range from 240 degrees to 450 degrees, and useful add-ons like Argan oil and a heat glove, it’s an economical and high-quality solution for any user. It also features 1-inch plates, dual voltage, and a rapid heating time.

Temperature between 240F-450F

The HSI Professional has optional temperatures between 240 degrees and 450 degrees Fahrenheit, giving it salon-level coverage for all hair types, from fine to coarse and thin to thick.

1-inch plates, curved edges

This flat iron has 1-inch plates featuring curved edges, making it easy to flip your hair at the bottom or curl it. While users with super long hair will prefer a wider plate, the 1-inch plate is great for most hair lengths. This model also has a swivel cord for easy styling, and a round body shape that makes curls look natural.

Dual voltage

This hair straightener is a dual-voltage flat iron, making it great for travel or as a gift for someone who lives overseas.

Comes with Argan oil and heat glove

The HSI Professional straightener comes with a small bottle of Argan oil, which is an exceptional treatment for helping dry, damaged hair recovery, as well as a heat glove that makes handling this high-powers flat iron comfortable and easy.

Strengths

Pure ceramic and tourmaline plates

It is made of 100% pure ceramic plates infused with tourmaline. Pure ceramic is different than most ceramics you will find on flat irons, which are generally baked onto aluminum or steel plates. These are known to chip and crack, creating uneven heating from the exposed metal. Pure ceramic is much more difficult to manufacture, but has much better heat diffusion and will not crack, chip, or peel. The HSI Professional is also reinforced with tourmaline, which is by far the best product you can get in a flat iron; it is a crushed crystal that emits a great deal of infrared heat which is safe and healthy for your hair.

Quick heating time

It can reach its max 450 degree heat in seconds, so you don’t have to wait.

Recommended for Asian and African-American hair

The HSI is one of the best straighteners on the market for very hard-to-straighten, easily damaged hair, like African-American and Asian hair. These hair types tend to be more likely to lose moisture and be more damaged by heat due to its porosity. Between its wide temperature range and high-quality materials, it’s able to deal with hair that many other straighteners only damage, or can’t straighten at all.

Weaknesses

No automatic shut-off

This flat iron does not automatically shut off after any amount of time, so always be sure to turn it off and unplug it after use.

Hard to use without heat glove

The handle of the HSI hair straightener does get very hot to the touch during use at high temperatures, so it’s not suitable for use without a heat glove or similar.

Overall Review

The HSI Professional flat iron is one of the top-performing straighteners on the market today, and will provide excellent, salon-quality ironing for any user with any hair type. It is gentle enough for fine hair and powerful enough for coarse hair, without causing undue damage to either. It would be a welcome addition to any home hair styling routine.
