One of the great things about hair products is that they constantly evolve and the Sedu hair iron is a great example of a hair product benefiting from Tourmaline. In fact Tourmaline has been used for many years in water filters and it's only been in recent years that the benefits of Tourmaline could be harnessed for the hair industry. This article was written to try and explain exactly what Tourmaline is and why it's used on hair straighteners.

Firstly, Tourmaline is a precious stone, whose colors include blue, green, pink, red, yellow, brown, black, bi-colored, tri-colored, and colorless. Tourmaline may be found in Brazil, Russia, Burma, Afghanistan, Malagasy Republic, Maine, California.

According to Egyptian legend the beautiful colors are the result of the Tourmaline travelling along a rainbow from the centre of the Earth up towards the sun. And on its way up it collected all the colours of the rainbow. This is why nowadays it is also called the "Rainbow gemstone”.

The name "Tourmaline” is derived from the Singhalese expression "tura mali”, which translates as "stone of mixed colours.” Ooohhh, now I'm intrigued. The very name already refers to the unique spectrum of colours displayed by this gemstone and no Tourmaline stone resembles another one. Tourmaline shows many faces and is thus excellently suited to match all moods and tempers. It does not come as a surprise, then, that ever since ancient days it has been attributed with magical powers. Tourmaline is supposed to be an especially powerful influence on love and friendship, lending them permanence and stability. I think it's about time I gave a Sedu Tourmaline hair straightener to my boyfriend!

Tourmaline has been used for sometime now in specialist water filters but only recently has it's benefits been used in the hair industry.

Why is Tourmaline used on hair straighteners?

It's all very well and good that Tourmaline is a beautiful gemstone but I'm sure I've never seen any sparkling gems on my Sedu tourmaline hair straightener so why is it used. I'm going to get a bit technical here: Tourmaline plates on your straightener generate negative ions and far infrared (FIR) rays. The FIR help to lock in moisture in your hair and also remove static which causes your hair to Frizz.

Due to the concentration of these negative ions hair-straightening time is cut in half and your hair is left feeling much softer and shinier.

Main benefits

·Micro-porous technology (locks in moisture)

·Ion field technology (seals in natural oils)

·Tourmaline Negative ion technology (removes static)

·Tourmaline Infrared heat for deep, long lasting straightness

It just goes to show that even precious stones have many more applications than sitting on your finger or around your neck. Although I think I still prefer a big diamond ring any day.
