context_page_description: A hair iron or hair tong is something people use to change the shape of the hair by heating it. There are three types of hair iron:
  Straightening irons, which straighten the hair.
  Curling tongs, which make hair curly.
  Styling irons, that can straighten and curl the hair.
context_section_description: Some better hair straighteners today have ceramic coated heating parts, which harm the hair less, and heat up faster than non-ceramic coated heating parts. Cheaper brands do not often have ceramic, but some have a paint-like coating that looks like ceramic plating. Cordless flat irons use lithium battery that can last up to 45 minutes, and other is heated by thermacell butane gas cartridge.
  Lots of more expensive hair straighteners use ionic and infra red technology, which helps to keep moisture and oils in the hair, and to stop static and frizz.
  Depending on the hair type, repeated use of hair straighteners, like most other heat styling tools, can cause varying amounts of damage such as split ends, thinning of the hair shaft and even causing hair to become brittle and prone to breakage. Generally, after extensive damage, hair will show signs of dryness and display an unhealthy appearance. However, many companies, such as L’Oréal and Tresemmé, have began to manufacture heat protection sprays and cream which aim to reduce the amount of damage that is caused by the use of straighteners.
  Hair straighteners should only be used on dry hair, unless they are specially made with vents to let the moisture out.  These sort of irons are usually called "Wet Dry" irons.
  Based on the materials used in the heating plates, hair irons can be classified as ceramic, tourmaline and traditional metal flat iron. Ceramic hair irons are believed to be gentle to the hair.
