Round brushes aren’t brand new on the market, but they are enjoying many years of popularity and are still as popular as ever. With new technology, they’ve evolved into heated brushes and manual brushes with added technology for the power blow-dry. However, if you’re unfamiliar with what all of the different types actually do, you’ll want to read our detailed round brush guide.
Some of the round brushes available blow hot air through vented channels down the body of the brush, others don’t blow hot air at all, with their bristles acting as the heat conductor and styling feature. Some are completely manual, with bristles – no mechanics involved at all!
There are also those that combine all these features including heating up bristles and blowing hot air. Which are the right types for what you need and how do you use them? We’ll give you all the hot round brush advice you need along with some of the best available to buy so you choose the right one for your hair type.

The Three Different Types of Round Brush
There are three different types of round brush and all are different to a flat brush because they are especially designed for curly hair or for achieving curls, whereas flat hair brushes do not create curls, they only glide through hair, or help to straighten it out.
- Simple Manual Round Brush – consists of bristles, a handle and no power-heat technology. You can use this one on damp or dry hair.
- Hot Brush – this looks like a manual round brush but comes with a power cord. You switch this one on and the barrel/and/or/bristles heat up to temperature. There is usually a variable temperature setting. The heat comes from the bristles and/or barrel and sets the hair into curls. You can only use this one on dry hair.
- Hot Air Brush – this looks like the aforementioned except it blows hot air through a vented channel down the middle of the body. It is also controlled using temperature and speed settings, usually positioned on the handle. You can use this on damp hair. Some of these types of hot air brushes have heated bristles too.
What Size Round Brush is Best For My Hair Type?
For short hair, choose a slim round brush, for long hair or thick hair, choose a larger barrel. However, if you want to achieve bubble curls in mid-length hair or longer, choose a slim barrel. Fine hair won’t work with very large barrels, choose slim to medium size.
You might find you need a couple of different size brushes, dependent on the size of curl you want to achieve.
What are the Most Popular Bristle Types and the Difference?
Flexible bristles are best for movement, as they grip the hair without snagging or pulling. However, you won’t find flexible bristles on all round brushes. Hot brushes tend to have rigid bristles made out of ceramic or a similar coating. These are good for heat conduction and for setting curls into already dry hair.
Boar bristles or natural bristles are good for manual round brushes as they are gentle on hair, they won’t pull or break it and help to detangle hair. They are also good for distributing natural oils over hair evenly, so it appears shiny.
Should I Choose a Heated Round Brush or a Manual Round Brush?
They both do different things. A manual round brush is good for styling with a hairdryer but you don’t need a manual round brush if you buy a heated brush (blow dry style or with heated bristles) as they should achieve the same finish. However, you might want to buy a slim manual brush to achieve small curls if you have a large barrel blow-dry brush. The latter is better for big blow dry styles rather than smaller, defined curls. Hairdressers always have a variety of both in their kits.
How to Use a Round Brush
Using a round brush is easy when you know how:
Manual Round Brush
This should be used with your hairdryer. Once you’ve washed and conditioned your hair, comb it through, apply a heat protecting spray and rough dry your hair so it is damp, then:
- Section out your hair and start at the back, unwinding the lowest section.
- Then using the round brush, wind the hair from the tip up to the root while applying heat with the dryer. Never hold the nozzle directly onto the brush.
- You will need to repeat this action until the section is dry, then pin the curl to your head before moving onto the next section.
- Repeat all over the head until every section is complete.
- Finally, release all the curls and smooth on some serum to keep the curls shiny and frizz-free.
- You can also use a round brush on dry hair to revive your style in between washes. Follow the same principles above.
Hot Blow-Dry Round Brush
Use instead of a hairdryer and manual round brush, here’s how to use it:
- Wash and condition your hair.
- Comb it through to remove any tangles and apply a heat protecting spray.
- You might want to let your hair air dry until it is just damp or use a hair dryer to get most of the moisture out of it.
- Then split your hair into sections and start at the back.
- Using the air styler wind the hair around it from tip to root and apply the heat. Within one or two passes your hair should produce a beautiful curl.
- Pin the curl to your head and repeat with the rest of the sections until complete.
- Finally release the curls and smooth on some serum to add extra shine.
- The hot brush is ideal to use in between washes to revive your hair style and can definitely be used on dry hair.
Heated Round Brush
This should never be used on wet hair and is not a blow dry brush:
- Wash and condition your hair as normal.
- Comb it through and apply a heat protecting spray.
- Either let your hair air dry completely or use a hair dryer but never attempt to use a heated round brush on wet hair because you will damage your hair.
- Section out your hair and start at the nape of your neck.
- Switch on your heated brush and allow it to heat up to the desired temperature (it is better to start on a lower temperature and gradually raise it to the right temperature for your hair type, low for fine hair, medium for medium thick hair and high for coarse, very thick hair).
- Then wind your hair around the barrel of your heated round brush and move the brush from tip to root.
- Release the curl and pin it to your head.
- Repeat the same process all over your hair until you are finished.
- Next, unpin the curls and separate them with your fingers if you want to.
- Apply some serum to boost shine and you’re ready to go!
What Popular Hair Styles Can I Achieve With a Round Brush?
Whichever brush you choose, always use a heat protectant before styling It’s also best to section out curls, so you don’t miss any areas out!
- Bubble curls, use a small manual round brush and style from damp.
- For big, bouncy blow drying, use a big manual round brush with a hair dryer and move the brush up and down the hair length while applying heat. When you’ve dried a section, leave the round brush in and move to another section (it helps to have a couple of brushes). This sets the style for longer. When you’ve finished the next section, leave that brush in and unwind the brush from the previous section – pin back the curl. Repeat all over the head for big, bouncy, loopy curls
- To achieve a big blow dry, use a blow-dry manual round brush and dry as you normally would using the brush but without using a blow dryer. When you’ve dried a section, pin it back to set the curl.
- For in-between styling, the heated round brush (without blow drying feature) is good for adding curls to dry hair. Use the correct temperature; wind hair around the brush, allow it to set, unwind, pin curl back to the head and repeat all-over the rest of the head.
