What is the best hair straightener for me?

How does the hair straightener work?

Before continuing to talk about the irons, it would be good to remember how hair is formed, so we can have a better understanding of how these devices work.

The pilosebaceous follicle is the organ from which hair grows. This is composed, in turn, of a dermal papilla and a hair bulb.

The part of the hair that we comb every day is made of keratin cells. To keep the structure of the strand intact, three types of links are required:

Disulfide bonds. They are temporary heat sensitive bridges between the sulfur atoms and when they come into contact with the hot plates of the plate they can break or deform very easily. This explains why when using the straighteners, the shape of the hair changes.

Hydrogen bonds and salt bridges. The latter are formed between an acid and a base. During bathing or when in contact with water, the bridges break. Once the hair is dry they form again and the cycle restarts.

Is it necessary to buy a hair straightener?

What iron to buy? Features to keep in mind

Types of hair straightener

The material of the plates is probably the most important aspect to consider when buying a hair straightener . Since the plates are in direct contact with the hair and some materials can cause great stress on the fibers. Most users prefer ceramic plates and titanium hair straighteners , these being the most common on the market. However, there are other models that, although less popular , are just as effective. We will talk about all of them below.

Ceramic plates : They are the most common type of plates. They do not mistreat the hair and heat evenly over the entire surface. They are also the least expensive, although the more advanced models with special design features can be as expensive as professional-use hair straighteners.

Titanium plates : They are strong and durable. They are perfect for very long or thick hair, since they are less heavy than the others and provide the same benefits and results as ceramic plates.

Tourmaline plates : It is an advanced model and also expensive. Its results are exceptional, it leaves hair more shiny and healthy. The heat technique does not affect the hair directly and allows you to obtain a professional straightening in less time.

Straighteners : The shape of these straighteners is completely different, they work as a kind of rotating cylindrical structure to straighten the hair.

Mini flat hair straighteners : As their name indicates, they are small straighteners, ideal to carry in your bag or travel suitcase. They are very useful for touch-ups or minor work.


Not all hair resists the same temperatures. As a general rule, hair that is fine, brittle and / or already treated with chemicals have less tolerance to heat. While virgin and thick hair require higher temperatures to change its shape.

Fine hair (≤ 160 ° C). Regardless of the type of iron, it must have a temperature regulator. Fine hairs are almost always weak and tend to burn easily.

Normal hair (between 160 ° and 190 ° C). In this case a temperature control is not always necessary. Although if the hair is dyed, it is advisable to buy a straightener with a regulator, since it must apply less heat to avoid damaging the porous fibers.

Thick hair (between 180 ° and 200 ° C). Most irons reach temperatures of 230 ° C, although it is not recommended to exceed 200 ° C even for thick, curly or wavy hair.

The general recommendation is to have your hair completely dry and use some type of heat protection spray. Hair should also be kept hydrated to prevent breakage and loss of freshness and youthful appearance.


Depending on the use it will be better to buy a flat and wide iron or one with rounded edges of average or narrow size, the latter adapt very well to the lock of hair and are used to straighten, curl or wave.

Also, the type of hair (thickness and length) influences the size of the plates. Larger ones work well for thick hair, and thinner ones are perfect for fine and delicate hair.

There are basically 2 types of plates : Fixed (wide, medium thickness, mini plates and floating) and tilting.

Hair straighteners prices

There are as many prices as models available for sale. The more expensive plates usually have a number of special features, are of better quality, are more efficient and comfortable to use. The price range goes from very inexpensive plates around 20 EUR to models that cost several hundred euros such as the Corioliss C1 or C3 plate .

Additional features

Finish, controls (including heat regulator ), lock button, long swivel cord, cool touch tips, hanging ring, auto shut-off, heat and cool time, travel case.
