This is the flat iron I currently use as the main tool. I have no doubt you will fall in love with IR2 Ionic Infrared Flat Iron. Sutra Supreme considers this product to be its most silky tool ever. This flat iron also comes in black with rose gold titanium plates.

It measures 16 x 11 x 14 inches and weighs only 1.5 pounds, and it is slightly larger than the Sutra Beauty IR1 Flat Iron. It is intended for long or short hair as well as for taming curly, wavy, or frizzy hair.

Did you know that dryness and frizz come from positive ions in our hair? The IR2 Iconic Infrared Flat Iron has been carefully designed to release a large amount of negative ions to neutralize positive ions and reduce the amount of curls and static.

Are you a fan of black and gold rose titanium? Keep reading. Sutra Beauty IR1 1 inch flat iron is originally designed for heavy, thick, coarse, and damaged hair and can be used by professional hairdressers as well as hair lovers in their own homes.

Its dimensions are 12 x 2 x 4 inches and 1.8 pounds, and as such belongs to the category of classic and lighter hair straighteners.

The special feature of this device is the Infrared Light Beam inside its titanium plates penetrates deep into the cuticle of your hair retaining the natural moisture.

Because of this technology, after use, your hair will not be brittle and dry. The well-known negative ion projector technology is also an integral part of this hair straightener. Precisely because of it, after styling the hair will be shinier than ever.

Sutra supreme is known for using the latest hair straightening technologies, so it should come as no surprise that it is possible to achieve maximum results with just one pass through the hair.

This device has a special heat regulator that allows you to evenly heat your iron from 170ºF to 450ºF. Besides a good look, Sutra hair iron also adorns an LCD digital interface for precise temperature adjustment and monitoring.

And if you often come back to make sure it’s off, you’ll probably be thrilled with its smart shutdown as well – designed to shut down after 60 minutes. Fantastic, isn’t it?

If you are a fan of free movement, you will definitely like the 2.5 m swivel cable that does not get tangled. The swivel cord will allow you to operate the hair straightener at different angles without putting pressure on your wrist. The device also has a double voltage in the range of 100V to 240V which makes it suitable for travel.

I love the variety of colors Sutra offers. Here’s what I found in a local shop.

A special feature of this device is also found in the Infrared rays located on the upper plate and in the Ultra Violet frequency generator on the lower plate. Their combination allows you to iron your hair evenly without any damage. It is also important to note that this flat iron owns the cool tip technology to keep your hands safe.

Among the most interesting things associated with this ceramic hair straightening machine is definitely the manufacturer’s lifetime warranty. But what does that actually mean?

If your hair straightener is damaged, the manufacturer warrants that the Sutra Beauty team will repair or replace your defective device. Awesome!!! If you are a fan of extremely small and light flat irons, we believe that you will like the Sutra Beauty Mini Flat Iron as well.
