The Best Hair Trimmer: Our Picks

Buying and evaluation criteria for hair trimmers

In your search for the perfect hair trimmer, you will come across a very large number of different models. To help you make your choice, we have listed the most important aspects and provided you with useful information.

These are the criteria you should consider before buying a hair trimmer:

Operating time

The operating time of your hair trimmer can play an important role. After all, it is extremely annoying if the hair trimmer runs out before you can finish your shave or haircut. First of all, you have to distinguish between a hair trimmer with a rechargeable battery and one with a power cable.

A hair trimmer with a rechargeable battery is more comfortable to use, but can only be used for a limited time and needs to be charged constantly. A hair trimmer with a power cord can be used indefinitely, but the cord can be a nuisance and you are dependent on a power source.

Make sure you know whether your hair trimmer uses a power cord or a rechargeable battery.

If you choose a corded hair trimmer, you have unlimited use and do not need to charge the device. However, such a model is not very practical, e.g. for short trips or on holiday, and you are bound by the length of the cable.

With a battery-operated hair trimmer, you always have a shorter period of use and cannot use the device while you are charging it. However, this model is more practical when you are on the go, as you do not necessarily need a power source. It is also much more convenient to use without the cord.

The duration of use of a hair trimmer with a rechargeable battery varies depending on the model. As a rule, you can expect a usage time of 50 to 90 minutes once the device has been fully charged.

The charging time can also vary depending on the model. Most devices take between 1 and 2 hours to fully charge. Some models also have a quick-charge function. This allows you to charge your hair trimmer within a few minutes so that it lasts for one use.

Meanwhile, there are also some models that are operated by both battery and power cord. This means you can enjoy the advantages of both options. Nose hair trimmers are also often battery-operated.

Cutting length

If you want to use a hair trimmer or a beard trimmer, you should make sure beforehand that your hair length matches the cutting length of the trimmer. Depending on the model, the cutting length can vary greatly.

There are often two options for these trimmers. Some models have a rotary wheel with which you can adjust the cutting length. However, there are often trimmers with attachments that allow you to adjust the cutting length. Of course, the attachments take up more space in storage, but they are often less susceptible to damage.

The lowest cutting length for beard trimmers is 0.1 millimetres.

As a rule, the possible cutting length is between 0.5-44 millimetres. However, not all trimmers cover these cutting lengths completely. This means that many short hair trimmers often have a cutting length of 0.5-30 millimetres, for example. With long hair trimmers, on the other hand, you can also achieve longer lengths, but they are not always suitable for very short cuts.

The blades themselves are also very important in terms of the cut. They should be of good quality and self-sharpening. The blades can be made of different materials. Blades made of ceramic or steel are common, but some models also use titanium coated with carbon.

Of course, nose hair trimmers do not have attachments with different lengths, as the aim is really only to shorten the nose hair. However, there are sometimes attachments in the accessories, but these are then intended for trimming eyebrows, for example.

So with nose hair trimmers, you don't have to consider the variety of possible cutting lengths. However, it is important that the trimmer's blades remove the nose hair reliably and without plucking.

Possible uses

Some hair trimmers have additional uses, for which there are different names such as all-in-one hair trimmer. This means that you only need one device for different applications.

However, with some models you have to expect that the trimming result for the additional use will be somewhat worse than with the specific trimmer.

In the case of short hair trimmers, you will often find devices that can also be used as long hair trimmers or beard trimmers. The long hair trimmers, on the other hand, can sometimes be used for a full beard.

Extra functions are most common with the nose hair trimmers. They can often also be used for your ear hair and eyebrows. Some nose hair trimmers even have attachments for the beard, but these are only suitable for smaller areas or the contours of your beard.


The weight of a hair trimmer should not be underestimated. Especially for longer uses, the weight can have a big influence on how comfortable the shave is. In addition, an ergonomic shape and a lower weight are also healthier for you.

There is a wide variation in weight among the models. Beard and hair trimmers weigh around 180-500 grams. Nose hair trimmers are usually lighter and often weigh 70-190 grams.

The size of the trimmer is also related to the weight. You should pay attention to the width. For hair trimmers, a large width can be helpful because you can trim your hair faster. For a beard trimmer, a smaller width is better because you can trim narrow areas, e.g. around the mouth, more precisely.


Depending on the type of hair trimmer and model, there are often additional accessories. Possible items are:

  • Several attachments with different length settings
  • A charging station for hair trimmers with rechargeable batteries
  • Batteries especially for nose hair trimmers
  • Care oil for the blades
  • A travel case
  • A cleaning brush

The items mentioned above give you a first impression of the typical accessories of hair trimmers. Of course, other items can also be included in the set, for example, some hair trimmers even come with a small pair of scissors.

What types of hair trimmers are there?

In the following, we would like to introduce you to the four different types of hair trimmers. In addition, we have clearly presented the advantages and disadvantages of each type.

Short hair trimmer

This is the classic hair trimmer and is suitable for various short hairstyles. A short hair trimmer is usually not suitable for hairstyles with a longer length, but it is always worth paying attention to the possible length settings.

There is the largest selection of different models of short hair trimmers. As a result, some products also have a large number of accessories, such as care oil for the blades, several attachments, a charging station, a travel case or even a cleaning brush.

  • Perfect for a short haircut
  • Often with many length settings
  • Not ideal for longer haircuts
  • Many bad cheap products on the market

Long hair trimmer

If you don't want a classic short haircut but still want to trim and style your hair, a long hair trimmer is for you. You can often trim your hair up to a length of 45 millimetres.

With long hair trimmers, it is especially important that you pay attention to the quality of the blades. They should be sharp and, if possible, have the manufacturer's lifetime sharp blade designation. It is also important to have a high cutting capacity for long and thick hair. Some long hair trimmers are also suitable for trimming a full beard.

  • Suitable for longer hair
  • Some models are also suitable for a full beard
  • Often not ideal for short haircuts
  • Sometimes a little more expensive

Nose hair trimmer

Many people find nose hairs that have grown too long not particularly aesthetic. For this reason, many people resort to waxing to remove their nose hair. A nose hair trimmer is a much simpler and painless alternative.

Some models are still battery-operated, but there are also nose hair trimmers with rechargeable batteries. The device can very often also be used for ear hair and sometimes also for eyebrows.

  • Optimal for nose hair
  • Often also suitable for ear hair
  • Some models are suitable for eyebrows
  • Not suitable for a haircut
  • Also not optimal for beard with attachments

Beard trimmer

If you have a beard, the most important thing is that it looks well groomed. You can use a beard trimmer or beard trimmer for this. You can use it to trim a wide variety of beards and give them a well-groomed look.

What you can't use the beard trimmer for well is a complete shave of your beard hairs, the classic razor is better for that. The beard trimmers often have a very high number of adjustable cutting lengths, so you always remain flexible.

  • Optimal for the beard
  • suitable for shortening and styling your beard
  • Not suitable for haircuts
  • Not suitable for a complete shave

Who are hair trimmers suitable for?

Hair trimmers are actually suitable for anyone who wants to shorten their hair. With short and long hair trimmers you can save yourself a trip to the hairdresser, and with a beard trimmer you can shorten and style your beard. You can use the nose hair trimmer to shorten your nose and ear hair. They can also be used to trim the hairs on your eyebrows.

You can also shorten your body hair with some hair trimmers. It is best to follow the manufacturer's instructions.

How much does a hair trimmer cost?

Similar to classic shavers, there are also big differences in the price of hair trimmers. The cheapest models are often not recommended because they are not of good quality.

Since you can save on hairdressing costs with a hair trimmer, for example, or you also want an optimal result with nose and beard trimmers, you should not only look at the cheapest price for hair trimmers.

Type price range
Short hair trimmer approx. 15-160€
Long hair trimmer approx. 15-160€
Nose hair trimmer approx. 5-180€
Beard trimmer approx. 10-300€

Good entry-level nose hair trimmers are available for as little as €10. For other hair trimmers, you can find good products starting at around 30 euros.

The most expensive hair trimmers are often professional devices and therefore not absolutely necessary for private use. There are many hair trimmers in the 50-80 euro range that are absolutely convincing.

What are the alternatives to a hair trimmer?

Classically, you can of course use scissors to cut your hair. However, a haircut with scissors is much more demanding and usually takes longer. With a hair trimmer, for example, it is much easier to achieve the same length everywhere.

There is also the option of using a razor. In contrast to the 2 blades of a hair trimmer, this usually has a shaving head. This makes it possible to shave the hair completely. However, in this case you do not have the attachments as with a hair trimmer, which is why you do not have the variety of different cut lengths with a shaver.

How do you use a hair trimmer?

The exact use of your hair trimmer depends on the type and the specific model. Often there is a small instruction manual as a package insert for the devices. You can also find a lot of videos and tutorials online that explain the procedure.

The operation of the nose hair trimmer, on the other hand, is very simple and is explained to you in the package insert.

How do I care for a hair trimmer?

For optimal care of your trimmer, you should consider the following:

  • Cleaning: After each use, remove the hairs from your shaving head. This will prolong the life of your trimmer and prevent germs from developing. Some models have a brush in the accessories for this purpose, others are even waterproof and rustproof.
  • Attachments: If you have a trimmer with attachments, you must clean them after each use. The best way to do this is under running water, then simply let them dry.
  • Blades: Some blades need to be maintained with a special oil to prevent wear. For these models, the oil is usually included in the accessories.

Otherwise, you should simply handle your hair trimmer with care and make sure that it does not fall down during use or while you are charging the hair trimmer.
