How to choose your diffuser hair dryer

Currently, women can enjoy the many hair appliances on the market. Among them is the diffuser hair dryer! Here are the criteria to take into account in order to choose one that is efficient.

#1 - The power

This is a criterion not to be taken lightly, as the efficiency of a diffuser hair dryer depends essentially on its power. This is measured in Watts. In order to benefit from quality drying, you should choose a model with a power of between 1500 and 2500 W! The higher it is, the faster you will be able to dry your hair.

#2 - The size of the diffuser

You should also take into consideration the size of the diffuser before purchasing a diffuser hair dryer. Why? Simply because it is according to this that you will have the ability to make curls as well as larger or smaller waves. In order to obtain large curls, you will therefore need an appropriate diffuser!

#3 - The shape of the spikes

This is a significant criterion given that the shape of the spikes will determine the result you want to obtain! This shape will be different if for example you want a voluminous blow-dry or you simply want to have beautiful waves. Large pimples or small pimples, it's up to you to choose the right shape in relation to your needs at the moment.

#4 - The material of the diffuser design

For a diffuser to be reliable, it has to be made from sturdy and resistant material. Therefore, before you buy your hair dryer, first make sure that the diffuser has been made using silicone and hard plastic. This way, you can be sure that you will be able to use it for a very long time!

#5 - The type of hair

Finally, last but not least, it is essential to consider your hair type before selecting a specific model. Do you have thick hair? It is wiser to choose a powerful device. Do you have fine hair? Then you need a device with a concentrator! And if you have curly hair, the best option would be a device with moderate power and different temperatures to choose from.

How do I use a diffuser hair dryer?

Without going into too much technical detail, a diffuser hair dryer is a type of hair dryer with a special nozzle known as a "diffuser". The main function of the diffuser is to ensure a better distribution of heat. This way, the heat is not directed only to a specific area of your head. The benefits are considerable: preservation of the hair fiber, absence of frizz, perfect curls, gain in volume...

How to use this device correctly?

A diffuser hair dryer is a great ally for all women who use it. However, you need to know how to use it properly to get the results you want. But in general, this device is not complicated to handle. Here are a few tips to help you with this. First of all, make sure that the pins do not come into contact with the scalp. Don't dry your hair without first wringing it out! Always remember to work from the bottom up. Depending on the model, the appliance may be suitable for different hair types: wavy, curly, short or long. Finally, you should know that you can always make fine adjustments to the heat. If possible, check that your diffuser hair dryer has a "cold air" function. This will be useful for setting your style while keeping your hair shiny.

The different types of hair dryer diffusers

Diffuser hair dryers are highly technical devices. It is nevertheless important to know the 2 types of appliances that exist on the market to optimize the use and thus have beautiful hairstyles.

The large diameter diffuser hair dryer

The large diameter diffuser hair dryer has a few things to offer. First of all, it is the best way if you want to get soft curls. Plus, the result will be the most natural. However, if your goal is to dry your hair, a large diameter nozzle will be more respectful of your hair, especially if it is rather fragile.

As for the negative points, the large diameter hair dryer has its limits. Firstly, it is not really suitable for people with short or even very short hair. Secondly, for drying hair, it is not effective if you use it from the beginning. It is rather indicated to complete the drying, so it is in a role of "finisher".

The large diameter diffuser hair dryer is therefore designed for women with long hair. It is also the ally of those who unfortunately have fragile hair.

The narrow diameter diffuser hair dryer

The hair dryer with narrow diffuser is advantageous on some points. To begin with, it allows its user to save a considerable amount of time for drying her hair. Furthermore, it is able to give you the most amazing volume. In addition, with a small diameter nozzle, you have the possibility to ensure a very precise work.

On the downside, we can say that the narrow diffuser hair dryer has a few aspects that put it at a disadvantage. First of all, it is not suitable for all those with long hair. In addition, since the heat is concentrated in a specific area, fragile hair is also at risk of being damaged! Compared to a wide diffuser, the narrow diffuser is more "aggressive" to the hair.

The narrow diffuser hair dryer is thus dedicated to women with short hair. It can also be used without any problem by those with rather resistant hair.

Diffuser hair dryer or hair straightener?

Hair dryer diffuser

One of the big advantages of the diffuser hair dryer compared to the straightening iron is that its use does not affect the health of your hair. Because of the action of the diffuser which guarantees an optimal distribution of heat, your hair fiber is preserved. In addition to this, this appliance gives you a natural drying, gives volume and helps you to produce a wavy effect.

If you compare a diffuser hair dryer with a straightening iron, you will quickly realize that the former is more cumbersome and bulky. Therefore, it is difficult to put it in a handbag for example. Consequently, it is more complicated to take it with you! In terms of use, a diffuser hair dryer also requires more effort than a hair straightener, as it is less manageable.

Straightening iron

A straightening iron gives a lot of advantages to its users. For example, it allows you to easily take care of your hair. Secondly, thanks to it, you can achieve different hairstyles yourself. All this while saving a lot of time! Indeed, a few minutes are enough to enjoy a beautiful hairstyle. It is therefore very practical for people who are often in a hurry.

Despite all its advantages, the hair straightener does have some major drawbacks. If you use it too often, it can be harmful to your scalp. The main reason is that this kind of device is capable of reaching very high temperatures of 180 to 200 degrees. In such conditions, the protective layer of your hair may disappear!


Whether it's a diffuser hair dryer or a straightening iron, both are effective in caring for your hair! The straightening iron has the advantage of being practical, but it's clearly not the best option if you have fragile hair. And that's the beauty of diffuser hair dryers! Although they are larger, they respect the fragility of your hair!

Why buy a diffuser hair dryer?

For drying hair

There is nothing better than a diffuser hair dryer to effectively dry your hair. Thanks to the diffuser, the heat is distributed evenly. As a result, your hair fiber is well protected from the blow dryer's blast! The fiber in question is not dried out insofar as the heat is not concentrated on a single area.

To add volume to hair

A diffuser hair dryer usually has pins. When you use it, these spikes work by lifting the roots of your hair. The result is volume! If you're one of those women whose hair lacks volume, a diffuser hair dryer is THE solution to your problem. Plus, your strands will gain texture too.

To prevent frizz

One of the main advantages of a diffuser hair dryer is that it prevents frizz. But to do this, you need to know how to use it properly. Since your hair is not subjected to excessive heat, it is not at risk of dehydration. In fact, we know that dehydration is the main cause of frizz.

Perfecting curls

The diffuser hair dryer helps you to have beautiful curls while keeping their natural shape. To do this, you need to follow these few steps: position your head down and blow dry your front strands. Make sure you dry them from the bottom up. During the drying process, you must keep the machine in an upright position.

To protect the hair fiber

As a hair dryer, the diffuser hair dryer uses a flow of hot air in order to dry your hair effectively. But the only big difference is that this heat, which can be extremely high depending on the model, is distributed evenly over the different areas of the head. Therefore, the hair fiber is somehow "out of reach" of this harmful heat.

The best brands of hair dryer diffusers

In our opinion, the best brands of hair dryer diffusers in 2022 are :

Velecta Paramount

This English brand was founded in 1991. It owes its reputation largely to its high-end vacuum cleaners. However, thanks to its success, it diversified its offer and started to produce appliances such as fans or electric hand dryers. The brand has always placed innovation at the heart of its concerns. Its hair dryers are both efficient and durable.

It is a French brand founded around the 60s by two hair professionals established in Paris. It is known worldwide in the hair beauty industry. And if there is one device that has brought it to the top, it is without a doubt the curling iron. Nowadays, this brand stands out for its high quality products, but still within the reach of consumers.

The American brand Remington stands out in the design of electrical appliances related to the beauty sector. Among other things, it has designed the very first razor that runs on electricity. Not only are its products functional, but they are also highly appreciated around the world because of their reliability and durability.

This brand of French origin was founded in 1917 by a certain Léo Trouilhet. It mainly focuses on beauty products as well as those for textile care. It is one of the best brands concerning the universe of household appliances. Hair dryer, iron, hair clipper, depilator... the offer is quite varied. The brand makes sure that its appliances can remain within the reach of everyone.

The Velecta brand was created in 1936. Today, it is 100% French and stands out for its ultra-high performance hair dryers dedicated to hairdressing professionals. These appliances are known for being light, ergonomic and very quiet. This is for example the case of its Revolution 2.2 i, which stands out from the crowd by its great power, but also its extreme manageability.

Create curls with the diffuser dryer

With a diffuser, you can get curls even if your hair isn't wavy. To do this, you first need to apply a conditioner to protect your hair from the heat or a curl-revealing mask. Then, take a strand of hair and place the ends on the diffuser set to medium or low heat. Then move the unit in an up and down motion.

Clean your diffuser dryer

Your diffuser dryer should be cleaned regularly. This is because dirt, dust, hair and hair care products can clog the unit and cause it to overheat. To clean your dryer, make sure it is unplugged. Then, remove the filter on the back of the unit and clean it with clear water. Then dry the filter with a soft cloth before putting it back in place.

Put masks on your hair before you dry it

You should apply a heat-protective conditioner to your hair before drying it to protect it from the heat and provide shine. To ensure that your hair can properly absorb the product you're using, consider wringing it out first. Apply the protective conditioner all over your hair, putting less product on the roots than on the lengths.

Choose the right temperature

The temperature of the hair dryer should be set according to your hair. If you have fine or fragile hair, be sure to dry it on low or medium heat. On the other hand, if your hair is thick and curly, blow-drying on high heat will ensure the best results. So when choosing your diffuser hair dryer, opt for a versatile model that allows you to adjust the temperature to suit your needs.

Avoid touching your skull with the diffuser

The diffuser's spikes spread air and define your curls. So you shouldn't use them to massage your scalp. If you place the diffuser too close to or against your scalp, you're risking burns from the hot air. So, when you pull up your diffuser to dry your roots, your device should stop about 20 centimeters from your scalp.


How to find the right diffuser hair dryer?

If you have thick hair, your diffuser should have spikes and large air holes so that your hair dries quickly. Sock diffusers are especially recommended for people with frizzy hair. On the other hand, if you have tight curls you can use a model with long fingers capable of separating your hair while curling it. Basically, choosing your diffuser depends mainly on your hair.

How to properly dry hair with a diffuser? How often should you use a diffuser hair dryer? Can you use it on wet hair?

Beforeusing a diffuser, you should first rid your hair of excess water by dabbing it with a towel. Then apply your protective conditioner and detangle your hair with a wide-tooth comb. To use the diffuser properly, you need to tilt your head forward and place your hair in the nozzle. This way, the air will be able to spread easily throughout your hair.

By using your hair dryer with diffuser, you can dry your hair without harming it. This is because the diffuser spreads the heat evenly throughout your hair. You can therefore use it more frequently than a straightening iron. However, daily use is not recommended, as the heat may open the scales of your hair and dehydrate it. You should therefore alternate blow-drying with the diffuser and air-drying.

Diffusers allow you to save time by quickly drying your wet hair. Nevertheless, before using the diffuser, it is advisable to remove excess moisture with a towel. This will prevent water from getting inside the unit. If you want your hair to look natural, you can stop drying while your hair is still 20% wet.
