Truth behind the everyday hair straightener

Hair straighteners are one of the UK’s most popular cosmetic. Women as well as men are straightening their hair morning noon and night to achieve a sleek, controlled look. With the average pair of straighteners reaching a temperature of 230 degrees, hot enough to fry an egg, there are dangers to them that people may not be aware of.

A third of all women and one in five men now own a pair, and why would they not when you can grab this hair styling tool from as little as £10. Obviously a £10 pair will differ significantly to a £110 pair, but how far do they differ? And are we spending over £100 to ruin our hair?


Some hair straighteners have temperature control which means someone with thinner hair would not have to have the temperature as high because it would not take as much heat to get through their hair. Hair expert’s state hair cannot handle temperatures much above 180 degrees, hotter than this and the hair will start to break off, starting with split ends and then gradually moving up the hair.


More expensive brands tend to use Far Infrared Heat. This heats the hair from the inside out and therefore causes less surface damage. Tourmaline plates are a new product to hit the hair care world. Tourmaline generates negative ions that enhance the texture of the hair. It is a crystal powder on the plate and because of this it means the plate heats up quicker, therefore hair can be styled quicker, leaving you with minimal damage.

Hair product company GHD refused to comment on why there is no temperature gage on their straighteners but do, like other hair styling companies, recommend to use hair care products before straightening.


Good straighteners say you will only need to pass the irons through one piece of hair once for it to be straight, repeatedly going over the same piece of hair is taking nutrition from it and actually burning it.

My top tips to having beautiful straight hair are simply to:

  • Apply a serum or heat protection spray to your damp hair. This will lock in hair nutrients and create a barrier between the hair and the irons.
  • Let your hair dry naturally first so you are not doubling the heat on your hair by blowdrying.
  • Divide your hair into sections.
  • Straighten one piece at a time and do not go over the same piece more than once, unless of course it is not as straight as you want it to be.
  • Brush each section at the same time as straightening.

I went out to Canterbury and asked what people thought the problems with hair straightening are.
