how_heat_styling_works-e1371069120329Hair straighteners are handy styling tools that make use of heat to re-shape hair; these devices come in varying types, but each one has the same basic concept. A hair straightener, also known as a flat iron, consist of two metal plates that are electronically heated, once they reach the desired temperature. The two plates are used to press locks of hair and straighten them out, old hair straighteners only had iron plates and had no heating controls, once turned on they would continue to gather heat till they were turned off. Since then, hair straighteners have undergone a lot of improvement and have now transformed into easy to use tools that do minimum damage to your hair and straighten it out evenly.

When hair is pressed between the two plates, a negative charge is created that locks moisture inside the hair, this is a crucial part of the straightening process as it ensures that your hair does not get excessive heat damage and that once it has been straightened it stays that way for a while. Also, the heat and negative charge break down the hydrogen bonds of hair and cause it to lose its shape, straightening it out. A larger negative charge means a better straightening job; this is why hair straighteners with ceramic plates are far superior to those with iron or titanium ones, not only does ceramic have a bigger charge, it also provides a more even heat distribution.

The quality of the plates determines how effectively can a straightener straighten hair, but that’s not the only part of the straightener that matters, to provide consistent straightening, a straightener should be able to produce a decent amount of heat. Flat irons have different heat settings; most modern ones come with knobs and digital controls that let you choose a temperature, once thoroughly heated a straightener’s temperatures can range from 200 to as much as 300 degrees Celsius. Modern flat irons have various sensors embedded near their plates that let them keep track of heat distribution and adjust their settings accordingly, and unlike their older versions, once they reach the required temperature they automatically stop heating themselves. A lot of straighteners nowadays have a self-turn-off function that prevents them from overheating and turning into potential fire hazards if left unattended.

Depending on your hair type, you need different levels of heat to get the job done, weak and frizzy hair requires low heat to be straightened out while more stubborn hair types need a significantly higher temperature to make them go limp. If a hair straightener has high-quality plates that can produce a decent amount of charge, then they can give the hair a glossy finish that looks great. A hair straightener is a lot more than just a heated tool that smooths your hair; there’s a lot of science behind these styling tools that makes them efficient and safe for your hair, allowing you to have picture perfect hair whenever you want it.
