Heated Beard Brush vs. Round Brush and Blow Dryer

A round brush and a blow dryer give you a better looking beard than a heated beard brush does, and the reason is shape. A round brush curves the hair around its barrel, so the beard bends outward and the profile it leaves is convex, full and rounded. A heated brush pulls the hair flat against your face, so the profile it leaves is concave, scooped in toward the jaw. Same beard, same length, completely different result. The catch is that the round brush takes practice and the heated brush does not.

Which is better, a heated beard brush or a blow dryer?

The dryer and round brush, if you are willing to learn it.

This is not a case of an old tool being better because it is old. It is a case of two tools doing physically different things to the hair. One presses and one curves, and the shape you end up with follows directly from that.

The heated brush has a real advantage, which is that it is easy. You get a predictable result on the first try with no technique. If you are rushing out the door, that counts for something. What you give up is the shape.

What is the difference between a convex and a concave beard?

It is the outline of your beard seen from the side, and once you have the words for it you cannot unsee it.

Concave curves inward. The beard is pressed down against the face and the silhouette scoops in toward the jaw. It reads flat, and it reads like something was done to the beard rather than the beard growing that way.

Convex curves outward. The beard bulges gently away from the face and the silhouette is full and rounded. It reads like the beard is growing out from your face rather than being stuck onto it.

Go and look. Pull up photos of your own beard first, then start noticing it on other men. Most people have never had a name for the thing that was bothering them about a photo of themselves, and this is often it.

Why does a heated brush leave a concave shape?

Because of what it physically does to the hair as it passes through.

A heated brush has a flat or nearly flat working surface, and you draw it downward along the beard. The hair is pressed between the brush and your face. Heat sets the hair in whatever position it is held in, and the position it is held in is flat. So the beard dries straight down and close, and the outline follows the shape of your jaw rather than standing off it.

Nothing is malfunctioning. It is doing exactly what it is built to do. Straightening and flattening are the same motion.

Why does a round brush leave a convex shape?

Because the hair wraps around a cylinder instead of lying against a flat plane.

As you roll a round brush through the beard, the hair takes the curve of the barrel. It leaves the brush bending outward and away from the face rather than pressed toward it. Dry it in that position and it keeps that position, which is where the fullness comes from.

The shape comes from the curve of the brush. Not from the heat.

How do you blow dry a beard with a round brush?

The sequence matters as much as the tool, and most of it is the same routine you should be running anyway.

1. Start at about 70 to 80 percent dry

Towel the beard down to damp. Not dripping, because product slides off a soaking beard and the hair is too heavy to hold a shape. Not dry, because by then the beard has already set and you are fighting it.

2. Product goes in while it is still damp

A beard butter and a beard oil, in whichever order you prefer. Noble's butter is wax free, so it works either way. We do butter first, because it is built to reach the skin and we would rather it get there before anything else is in the way.

3. Low heat

This is where most men go wrong. They turn it up, cook the hair, and end up with something wiry and dull, then blame the dryer. Low heat with a round brush produces a smoother result than a heated brush will. The heat is not doing the work. The drying is.

4. Work in small sections, underneath and outward

Go in horizontally with the barrel, under the beard, and roll outward as you are going in. The roll and the entry are one motion, not two. That is what bends the hair away from the jaw instead of pressing it flat, and it is the step that decides convex or concave.

Take small sections. This is the part that sounds like more work and is actually less. A small section gives the barrel something it can grip and turn. Grab too much at once and the brush slides through without taking hold of anything, and you end up going back over the same patch.

5. Let it finish drying in that shape, then leave it alone

Hands out of it. Every pass you make through a drying beard resets the shape it is going to keep.

It takes a few attempts before it feels natural, which is the honest tradeoff against the heated brush. It is worth the few attempts.

What size round brush should you use?

Match the barrel to the length of the beard.

Small barrel for shorter beards. A short beard needs a brush that can actually get in under it and take hold of the hair. A large barrel skates over the top and never grips.

Medium barrel for longer beards. More length wants a wider curve, and a medium barrel moves through it in fewer passes while still giving you the outward bend.

Being able to choose the size at all is part of the point. A heated brush comes in one bulky format and you work around it. With a round brush you pick the tool that suits your beard, and you can get it in horizontally under a short beard where a heated brush simply will not fit.

Why does drying position matter so much?

Because hair sets in whatever shape it dries in, and that is the mechanism under this entire article.

Hair holds its shape with hydrogen bonds. Water breaks them, which is why a damp beard is pliable and will go wherever you put it. As it dries those bonds reform around the position the hair is sitting in, and that shape holds until the hair gets wet again. Bed head is the same thing happening by accident overnight.

So a beard is not really styled by a tool. It is styled by what position it happens to be in while it dries. The tool's only job is to put it in the right position and hold it there long enough. There is more on this in why won't my beard lay flat.

Is a heated beard brush bad for your beard?

Not inherently, and that is not the argument being made here.

The case against it is aesthetic, not safety. It gives you a concave shape, and once you can see that, most men decide they want the other one. Use low heat with any tool, including this one, and do not run heat through a beard that has had nothing put in it.

If you are going to keep using one, brush underneath and outward rather than straight down the face. Get the brush under the beard and lift away from the jaw. You will not get the full convex result, but you will get closer to it than you will by pressing down.

The difficulty is that heated brushes are bulky. Working underneath a beard with one is awkward, and that bulk is a large part of why the round brush wins. You can get a round brush where you need it.

Do you need product before blow drying?

Yes, and this one is not optional.

Heat on an unconditioned beard is how beards get wiry. Conditioning first gives the hair something to hold onto while the water leaves it. Whatever tool you are using, product goes in while the beard is still damp, before any heat touches it. If you are missing the pieces, that is the wash and conditioner at the start and the butter and oil before drying.

Does this work on a short beard?

Yes, and the difference shows up faster than people expect.

Short and coarse hair sticks out sideways for the same reason a long beard flips the wrong way. It dried in that position. Shorter hair has more spring in it, so directing it while damp matters more, not less. Use a small barrel brush and it will take hold.

How often should you do this?

As often as you wash, which is not every day for most men.

Wash when you have actually got dirt on you, and more often if you use product daily, since butter and oil collect dirt from the air over the course of a day. Any time you wash, condition. And any day you want the shape, the beard has to be wet at some point, because wet is what opens the window. Water alone in the shower counts on a day the beard is not dirty.

What you need

A round brush in the right barrel size, a dryer with a low setting, and a conditioned beard. The brush and dryer you may already own. For the rest, the 4-Piece Beard Care System is the wash, conditioner, butter and oil matched to one scent, which also keeps two competing fragrances off your face.

Our founder spent fifteen years behind the chair before Noble existed. Convex versus concave is the thing he says he cannot stop noticing on other people, and it is the single fastest change most men can make to how their beard reads.
