What Makes a Beard Trimmer Great For Long Beards?

A beard trimmer is an essential part of any man’s grooming kit. It holds ample advantages over other shaving means, such as a razor. A few of these benefits are as follows.

Can Be Used For a Variety of Different Purposes

Beard trimmers are widely used for the purpose they are built for, i.e., to get rid of excess facial hair. However, beard trimmers are also great for removing unwanted hair from other regions such as around the neckline, hairline, ears, body hair, etc. 

Suitable For Sensitive Skin

Men with sensitive skin struggle a lot in finding a face tool that would not irritate their skin. They tend to end up with bumps, ingrown hair, or damaged skin by using an unsuitable product. As a result, most men give up and let their beards grow. However, with a beard trimmer, such incidences are much less likely to happen even on regular use. 

Safe and Cost-Friendly

It is no hidden fact that beard trimmers are much safer than regular open-blade razors that always carry a risk of causing cuts and tugs. In addition, beard trimmers also come with other protective additions such as a plastic cover to make the hair trimming process safer. The ergonomic grip on this tool only adds to the comfort of use. 

Moreover, beard trimmers are also comparatively cheaper as they are a one-time investment as compared to constantly replacing disposable razors. 

Can Be Used on the go

Beard trimmers, if cordless or battery-powered, are great for people with a busy schedule. These units can be taken anywhere and can be used wherever you want since they are more convenient.

Cautious Considerations to Keep in Mind

A beard trimmer is almost an investment as it is a tool that is expected to last for long. As with any investment, it needs to be done carefully. Therefore, read the must-have features any good beard trimmer must have to qualify it as the one that you buy. 

Strong and Sturdy

It is important that the beard trimmer is made of high-quality material so that it endures wear and tear and last you for a long time. Stainless steel models are highly recommended, but they tend to be on the pricier side. Strong plastic options are equally as good, though, as long as it guards the machine against damage. 

Type of Blades

Blades are the essential part of a beard trimmer; therefore, extra attention needs to be paid to this feature. There are many options available such as self-sharpening, double-sharpened, carbon-steel, etc. All of these are of high quality and provide close, safe cuts. 

Cordless or Corded

Although corded options are not bad, they are simply not very convenient. Cordless options are preferred by many as it is easy to carry them and can be taken wherever you go, allowing use whenever you want. 

Attachments and Add-Ons 

Different attachment heads and combs are a crucial part of a beard trimmer kit, especially for people with longer and bushier beards. The variable attachments allow you to style your beard the way you want while the combs ensure you are left with a beard of the exact length that you want after the trim


An ergonomic, contoured body design is considered to be the best for a good hand feel when using a beard trimmer. Moreover, the shape, size, and weight should also be good enough to help you feel comfortable with it near your face. 

In addition, a waterproof model is an extra benefit as most trimming and grooming is done in the bathroom sink, a place where you are likely to find water. 


Maintaining a long beard requires effort and attention at least two to three times a week, which means you need a device that you can regularly use with ease. Using this guide, it should now be easy for you to pick out a beard trimmer for long beards. You can now narrow down your search to the model that has features and price that fit you best. 

People Also Ask

Users tend to have plenty of questions about beard trimmers. However, there are a few that usually everyone asks. Answered below are the most asked questions to help you understand your device better. 

Will Long Beards Dull Trimmers Faster?

The length of your beard does not affect the performance of your trimmer. A high-quality trimmer remains good regardless of the length of your beard. However, it does consume more battery with long beards. 

How Long Do Beard Trimmer Blades Last?

This largely depends on the maintenance of your blades. Regular oiling and cleaning ensure a longer blade life. It also depends on your use. With proper maintenance and care, a trimmer blade can last about 3 to 6 months. 

How Often Should I Clean my Trimmer?

Hygiene and cleanliness are important to everyone. It is good to clean your trimmer with a brush and water after every use to make sure no hair or dead skin cells are left behind. However, a deep cleanse with a disinfectant is great every once in a while. It can be done by simply disassembling the trimmer and submerging the part in disinfectant water.
