Before we compare the Solia flat iron with that of the Sedu flat iron, we'll first list off some of the main features shared by both. Sedu flat irons come with two different plate widths: 1-? and 1 inch. Solia flat irons come with four different plate widths but its 1-? and 1-? inch models are its most popular and as these roughly match the plate sizes of the Sedu, so we'll compare these models against Sedu.

Both the Sedu and Solia flat iron come with tourmaline plates. If you're going to buy a flat iron you must buy a model with tourmaline plates. Basically, tourmaline gives off negative ions, which have been shown to lock in moisture into the hair follicle and help to straighten hair without excessive heat damage. Both Sedu and Solia are American-designed flat irons, though both are actually manufactured in the Far East. Both come with 1-year warranties. Both have quick heat-up times of less than 30 seconds.

Both the Sedu and Solia flat iron come with variable settings. However, the Solia just nudges ahead because its heat setting ranges from 140F - 450F, whereas the Sedu flat iron has a slightly narrow range: 240F - 410F.

When it comes to weight the Sedu wins out over the Solia flat iron. The Sedu 1" tourmaline flat iron is 0.5lbs whereas the Solia 1 ?" tourmaline flat iron weighs in at 1.2lbs. Weight does make a difference because when straightening your hair the flat iron you use will start to feel heavier and heavier.

You may not be too interested in what the flat iron looks like, but f you are, the Solia tourmaline flat iron looks far more stylish that the Sedu. The Solia has a better, more contoured design, than does the Sedu.

The above are minor differences and neither Sedu nor Solia come out on top. However there are two further reasons why the Solia Ceramic Ion Flat iron comes out the clear winner: the Dynamic Alignment System used by Solia flat iron and its price.

The Dynamic Alignment System used in the Ion ceramic plates of a Solia flat iron is self-adjusting, which helps to provide perfect contact between hair and plate. This means that hot spots are avoided that can cause damage to hair. The Dynamic Alignment System also works as a pressure equalizer that helps avoid any specific pressure points during the straightening process, thereby allowing the Solia flat iron to work through the hair smoothly without pulling.

There's no avoiding the price differential between a Solia and Sedu flat iron. A Solia tourmaline flat iron is about three-quarters the cost of its comparable Sedu flat iron. Both the Sedu and Solia flat iron are quality products and are amongst the best flat irons you can buy. But quality flat irons aren't cheap and the consumer wants value for money, so the price difference between the two brands make the Solia Professional Ion Ceramic flat iron a clear winner.
