Hair dryers are the kind of product that have such a varied offer in terms of prices and features that they often generate something very close to confusion. How do you know what the more appropriate to the needs from each person?
Choosing a robot vacuum cleaner: main models and aspects to consider
Beyond the money that everyone can –and is willing to– spend on the purchase of a dryer (there are models that cost 15 euros and others whose price exceeds 500 euros), there are a good number of peculiarities that it should be taken into account when choosing it. Here are some of the most important ones.
1. How will it be used
This first question is very basic and may seem obvious, but it has its importance. In general, we can talk about three types of dryers: traveling, domestic or professional. Most brands offer products in all three categories.
For those who have to carry the dryer with them on their trips, the most appropriate will be a small one, with folding or detachable handle. If it is to be used for home and everyday use, the most logical a priori choice is one of medium quality, which without being too sophisticated fulfills its essential functions.
Now, if the objective –both if it is every day or only on special occasions– is to spend a lot of time drying hair or sport a “barber” hairstyle, the most recommended option would be that of a professional dryer, which offers a series of possibilities that the others lack.
The potency of the artifact is perhaps its most important feature, since the quality of the results that can be achieved will largely depend on it. Most of the dryers on the market offer powers between 1,000 watts (the smallest) and up to 4,000 watts (the professionals).
Higher power allows the device to reach higher temperatures and more force in the expelled air. Thanks to this, drying is possible in less time. But you have to be careful, well it’s not just a matter of time: the heat and the air flow must be regulated according to the type of hair and the hairstyle to be achieved.
In general, dryers with a power of between 1,600 watts, for people with fine hair, and up to 2,000 for thick hair, are considered suitable for home use.
3. Temperature regulation
As we said, it is not only the power that matters. The possibility of regulate the temperature it is key to not damage the hair and to obtain different results. Straightening the hair requires more heat and a stronger air flow. If you want to get curls, instead, the flow should be less powerful and the temperature lower.
For very fine or brittle hair, very intense and frequently applied heat can be very damaging. That is why, for these people, dryers with slightly less power are sufficient. Some professional dryers include a thermal sensor, which detects excess temperatures and reduces it automatically.
And it is also important – in particular if it is to be used for elaborate hairstyles – that the dryer has the cold air option. Applied after the hot one, the cold one allows a greater fixation and, therefore, a hairstyle with greater durability.
4. Size and weight
These are other factors that may seem obvious but cannot be ignored either. As good as a professional dryer may perform, if it is too heavy or uncomfortable, it will likely end up being a bad investment.
Ideally, the dryer is ergonomic, lightweight –That is, it has a reasonable weight– and, if possible, with a long and thick cable (and that complies with the safety requirements to avoid electrical risk). In this way, it is easier to use and also extends the useful life of the product. There are even wireless models.
For the rest, if the dryer is to be used for trips to other countries (especially outside Europe), another element that should be taken into account is its ability to adapt to other voltages.
Depending on the intended use of the dryer, accessories and complements may be essential. One of the most common – included in practically all models – is the air concentrator, which allows airflow to escape through a narrower opening for smoother styles.
The diffusers They also come with almost all hair dryers on the market, and they serve the opposite: curly hair and hair with a lot of volume. For the rest, there is also a great variety of nozzles to achieve other effects: some help to give volume to the roots but leave the rest of the hair smooth, others have a design that allows heat to be applied without affecting the hair directly, etc.
The dryers have incorporated important technological innovations to improve their performance and contribute to the care of the hair. The best known is the ion use, which are particles with an electrical charge. In the case of dryers, with a negative charge.
Thanks to this negative charge, these ions reduce the surface tension of the droplets that moisten the hair, turning them into even smaller droplets. With what objective? On the one hand, that disperse more easily. On the other hand, promote its absorption by the hair itself.
The result is shinier-looking hair, as well as reduced drying time. Another widely used technological resource is tourmaline, a mineral that emits infrared heat and thus enhances the effect of ions.
And another more or less recent addition in the composition of the dryers is the ceramic or porcelain pieces, which help to avoid temperature variations that damage the hair. In this way, it is easier to give the hair the desired shape, and consequently time is saved and damage to the hair is avoided.
