What is a straightening brush and what are its advantages?

The straightening brush is a beauty appliance that is very similar in format to a conventional hairbrush, but with the difference that it is plugged into the mains. Its function is similar to that of a straightener, but it mistreats the hair less and leaves it looking healthy and natural.

The straightening brush has ceramic-coated bristles that mould and straighten the hair quickly when heated. It is also very easy to use and its temperature can be regulated according to the type of hair, adapting to each use and specific need.

This fantastic product is perfect for eliminating annoying frizz in just a few minutes, and can be transported from one place to another in a comfortable, practical and simple way, due to its small format and light weight. In addition, there is a wide variety of models, sizes, formats and functions.

  • Leaves hair straight, smooth and shiny
  • Easy to use
  • Practical and convenient to carry
  • Does not damage hair like straighteners
  • Eliminates frizz
  • Not usually as effective for frizzy hair
  • Some models are a bit heavy

Digital, duo, mini or battery-operated straightening brush – what to look out for?

Straightening brushes come in different varieties, adapted to different uses and needs. Here are the main features of the most common and most commonly used models, so that you can choose the variant that’s right for you.

Digital straightening brush. This straightening brush has a digital control panel with an automatic shut-off function in case you forget to leave it on. In addition, its ceramic coated bristles have antibacterial properties that prevent the formation of impurities, keeping them clean and hygienic at all times.

Duo straightening brush. This straightening brush has a dual head that leaves your hair straight and silky in just a few strokes, and just like the digital brush, it has an automatic shut-off programme and antibacterial ceramic bristles. It is ideal for very curly hair.

Mini straightening brush. This straightening brush is specially designed for travel, as its small and light format allows it to be easily, practically and comfortably carried in your handbag, purse, backpack or suitcase. It also has a voltage adaptable to most electrical sockets.

Battery-operated straightening brush. This battery-operated straightening brush emits up to 80% more ions than other models and removes frizz from hair, leaving it smooth and straight. It is also very lightweight, making it ideal for travel.

What about ionic brushes?

Many of the straightening brushes have ions, whose main function is to eliminate frizz and frizz caused by environmental factors such as humidity, the use of chemicals, or the characteristics of each type of hair.

Ionic brushes are responsible for “injecting” negative ions into the hair, which are responsible for counteracting static and provide hair restoration. The result is straighter, silkier, healthier and more balanced hair, so it is a feature to consider when buying.

Is there any special care for cleaning?

To extend the life of the straightening brush, you should take certain precautions when cleaning it, as proper hygiene will ensure proper operation and a much longer service life. Therefore, you should follow the following steps when cleaning the brush:

Make sure it is switched off. Before you start cleaning, make sure that your straightening brush is switched off and cool, otherwise you run the risk of burning your skin and short-circuiting the appliance due to moisture.

Clean hairs and dirt. It is essential that you take the time to remove any hairs, lint or other dirt from the brush each time you finish using it to keep it clean and ensure it works properly.

Apply detergent. Although you can use any kitchen detergent, it is best to use an anti-grease detergent to more easily and effectively remove grease from the brush, whether it is the result of hair oil, styling creams, straightening products or hair nutrition.

Purchasing criteria

In this last section we will discuss the purchasing criteria that will help you select the most suitable hair straightening brushes for you, depending on the characteristics of your hair. This information will be of great help to you at the time of purchase!

Hair type

A very important factor when choosing the most suitable hair straightening brush is to take into account your hair type, as the effect will vary according to each hair texture. Here are some tips related to this topic:

Straight hair. You may ask: Why would straight hair need a straightening brush? Because even if hair is naturally straight, it can suffer from dryness and frizz due to the continuous use of hair dyes, blow dryers, straighteners, straightening products, etc., or due to humidity, among other factors.

That’s why a straightening comb helps reduce static, and gives more smoothness and shine to the most damaged straight hair. You can use a variety with anti-static ions, or simply choose a basic model that allows you to straighten your hair in just a few passes.

Wavy hair. In this case you can opt for a duo (or double) straightening brush, which will give you a deeper straightening in just a few strokes. It’s also important to consider an anti-frizz ionising system to eliminate static or frizz.

Curly hair. If you have curly hair, a straightening brush is probably not enough and you may need to use a flat iron as well. You can use the straightener and the straightening brush for daily brushing, trying not to overly stress your hair with constant use.


Most straightening brushes have three adjustable temperature levels, adaptable to each hair type. We will now tell you which temperature setting is most appropriate, depending on the thickness and texture of your hair, for example:

Between 170° and 190°. This temperature range is ideal for fine hair, as it doesn’t require as much heat. You can also find straightening brush models with even lower settings, which can also be functional for fine hair textures.

Between 190° and 210°. Normal hair needs a higher temperature to straighten, so straightening brushes with these settings can work very well, taking into account the specific characteristics of each hair beyond its texture and thickness.

210° to 230°. These temperatures are suitable for thick and curly hair, which is more difficult to straighten. Please note that these are the most commonly used settings, but you can get straightening brushes with even higher temperatures.

Material of the plates

The material of the plates of the straightening brush determines the temperature distribution along the brush, the heat retention, the quality of the brush and therefore its durability. In the following, we will describe the main characteristics of the raw materials most commonly used for the manufacture of this product.

Ceramic. This is the most common material used for the manufacture of straightening brushes, as it achieves an intense heat in a short time, and allows it to be distributed evenly throughout the hair. It is also a scratch-resistant and durable raw material.

Titanium. Titanium is a premium material in the production of straightening brushes, as it withstands very high temperatures and is extremely durable. Its use is rather professional, so many salons have it among their hair straightening accessories.

Cable length

The length of the cable is also an important aspect to consider, as its length will limit or extend our possibilities to move while using the straightening brush. Below, we will discuss the measurements of this complementary element.

1 m cables. Older models of wire brushes had approximately 1m long cables, which limited mobility quite a lot. However, if you are going to use this device in a place where there are sockets nearby, you don’t need the dimensions to be too long.

2m cables. Models of wire brushes with 2 m cables (usually 1.8 m) are very useful when you do not have plugs near the place where you use the brush, or when you are travelling and do not know where you can connect this electrical appliance. On the other hand, it is important that the cable is rotatable, since this avoids tangles and optimises the length of the cable. Modern brushes often come with 360° swivel cables, which are very practical, convenient and functional.


The different models of brushes differ in terms of their formats and uses, but also in terms of their additional accessories. In the following, we will tell you what some of these functional elements are and what they are used for.

Covers. Many straightening brushes come with protective covers to protect them from scratches, minor bumps, dirt and environmental factors such as humidity. This accessory is also very useful for carrying the brush anywhere, as it has adjustable handles.

Interchangeable brushes. These brushes have different variants of interchangeable bristles to suit different hair types. Although they are functional, they are not used as often as other accessories, so you should evaluate their use, as this will influence their commercial value.

Heat resistant glove. This glove is specially designed to withstand high temperatures, so it is used during brushing to avoid burns. This accessory is mostly applied in beauty salons where straightening brushes with higher thermal gradient are used. (Featured image photo: puhhha /
