Best beard trimmer for thick coarse hair – 5 insider picks…

If you have thick coarse hair finding the right trimmer will be paramount in making sure that you can keep the edges sharp. You’ll need to find a trimmer that has a sturdy build, sharp blades and a strong motor. Here we will take a look at your options for buying the best beard trimmer for thick coarse hair!

Be warned though – your glorious thick beard will need a premium product!

Finding the perfect trimmer for thick coarse hair is tough. My pick for thick coarse hair is the OSTER Fast Feed Adjustable Pivot Motor Clipper. You need a trimmer that has enough power to get through your beard and produce a clean edge! That’s why I only recommend corded trimmers.

Well done you on looking for a beard trimmer that matches the thickness and qualities of your hair!

You see, there’s a massive range of human hair thickness – from 17 to 180 µm (thats 0.00067 to 0.0071 in), a ratio of more than ten to one!

It also varies enormously in its growth pattern and density, not only from person to person but also in different areas of the same person’s face.

This helps us understand why there’s such a huge variation in people’s shaving and trimming experience. You can’t rely on your friend’s recommendation unless they have the same ethnicity, age, and hair density as you!

It’s our genetic make-up that decides whether we have thick or thin hair:

  • Europeans consider hair with a diameter of 0.04 to 0.06 mm as thin, a diameter of between 0.06 and 0.08 mm as normal, and hair with a diameter between 0.08 and 0.1 mm as thick.
  • Asian hair is significantly thicker. The average diameter of Asian hair is 0.08 to 0.12 mm.
  • European hair has a flatter shape, while Asian hair has a rounded cross-section.

In a hurry? Here’s my pick!

Buyers guide for best beard trimmer for thick coarse hair

When you are looking for the best beard trimmer for thick coarse hair you need POWER and lots of it! Here’s what I think you should look for in a trimmer if you need the best beard trimmer for thick coarse hair!

Get corded not battery

Battery-powered trimmers will struggle to cut really thick coarse hair consistently. So make sure that you can plug it into the wall so you can be sure to get those lines that your beard needs to look sharp!

There’s nothing more frustrating than the whining sound of a trimmer’s battery dying! If you’ve got thick coarse beard hair – you’ll be all too familiar with that sound. Plus, corded trimmers tend to be much more reparable than battery-powered trimmers. They are also more environmentally friendly – if that is your thing – no toxins released into the environment upon disposal!

So, do yourself a favor and get a corded trimmer and reap the rewards of power and repair-ability!

Don’t buy cheap – you’ll regret it

Yes, we have all been there!

When we start looking for products and we stop looking at the features and quality of a product and we end up comparing on price!

“…this one has all of the features I want BUT THIS ONE is half the price…”

Trimmers that are half the price are half the price for a reason. Most of the time that reason is that they have been made to break. Planned obsolescence is a real concern when you are looking for quality products.

Do your self a favor and re-frame that thought process. Sure it’s more expensive but you’ll only have to buy once every 20 years…not every couple of years like with the cheaper products.

This will cause you a lot of hassle in the long run – especially if you have a thick beard!

Get replaceable blades!

The most important part of a trimmer is the cutting surface and blades.

It you have thick hair – it makes sense that they will dull quicker than someone with lighter or thinner hair.

If you are looking for a great beard trimmer for thick coarse hair I’d encourage you to only get trimers with replaceable blades. Also, because you can take them off you can clean the hair from underneath the blades and oil it up well – something I do once every couple of months!

Replace them about once a year and you’ll be sure of a proper cut every time!

Patents for beard trimmers for thick

This topic has also gained a lot of traction from innovators!

Here are a couple of patent applications that adjust the trimming power based on how thick the trimmer senses the beard to be…
