(Redirected from Curlers)
A 'hair iron' or 'hair tong' is a tool used to change the structure of the hair with the help of heat. There are two general kinds: 'Straightening irons', used to straighten the hair, and 'curling irons', used to make the hair curly. Straightening irons may also be called flat irons, but not to be confused with clothes flat irons.
Hair straighteners work by breaking down the hair's hydrogen bonds found in the hair's cortex, which cause hair to bend and become curly. Once the bonds are broken, hair is prevented from holding its original, natural form, though the hydrogen bonds can re-form if exposed to moisture. [1]
The first hair straightener was invented by Ian Gutgold using harsh chemicals in lotions applied to the hair and scalp. However, these preparations often led to scorched scalps and damaged hair.
Simon E. Monroe patented a hair straightener in 1906 that comprised metallic teeth that are combed through the hair,[2] while in 1909 Issac K. Shero patented a hair straightener composed of two flat irons that are heated and pressed together.[3]
Years later, Sharrell invented heated metal hair-care implements, such as hot combs. The hot metal straightener slid easily through the hair, causing less damage and dryness than previously-used techniques. Later, ceramic and electrical straighteners were introduced, allowing for adjustment of heat settings and straightener size.
Another method of hair straightening is the thermal Japanese hair straightening technique, which acts as a sort of "anti-perm". It is now available at many salons but is quite expensive and must be repeated on a regular basis.
High-end modern hair straighteners have ceramic heating elements, which cause less damage to hair, are more effective and heat up faster than non-ceramic coated heating plates. Less expensive brands usually do not have ceramic heating elements though some may have a paint-like coating that gives the appearance of ceramic plating.
Many high end straighteners claim to use ionic and infra red technology, which claims to seal in moisture and oils and to reduce 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" or "Wet to Dry" irons.
A revolution in the consumer market for hair straighteners was created by the introduction of the GHD brand which pioneered the introduction to the market of the ceramic heating element and plates. The market share of the GHD model increased significantly when HQhair was quoted in US edition InStyle magazine as having supplied one to Gwyneth Paltrow and thereafter HQhair were quoted in a number of other celebrity led publications such as Heat magazine and Now magazine linking the GHD to a host more celebrities.
According to the website HQhair.com the latest model GHD hair straightener is the GHD IV Mk4 Styler which has the dual-purpose function of straightening and curling the hair.
With the introduction of the Slikit ceramic cordless hair straightener the world's first Lithium Ion powered fully re-chargeable cordless ceramic tourmaline hair straightener was brought to the market so allowing consumers the convenience of straightening their hair while on the move without need to plug into a power supply.
Hair curling may be achieved through heated rollers, heated irons, steam-heated curlers, or by a perm. Modern curling irons are made of elements similar to that of straightening.
