How Big Of A Round Brush Should I Use?

The size of the round brush you should use for your hair is determined by its length and thickness, as well as the style you want to achieve. Here are some general guidelines to keep in mind:

  1. A small or medium round brush is appropriate for short hair (shoulder length or shorter). These brushes will make it simple to add volume and curls to your hair.
  2. A medium or large round brush is appropriate for medium-length hair (chin to shoulder length). These brushes will give you more control over your style and will allow you to achieve a variety of looks, such as straight, wavy, and curly hair.
  3. A large or extra large round brush can be used on long hair (beyond shoulder length). These brushes provide the most control and can assist you in creating smooth, sleek styles or voluminous curls.

It’s also worth noting that the size of the round brush you use will be determined by the type of hair you have. If you have very thick hair, for example, you may need to use a larger round brush to fully style all of your hair. If you have thin or fine hair, on the other hand, you may find that a smaller round brush works best for you.

Finally, the best round brush for you will be determined by your hair type, length, and the style you want to achieve. It may be beneficial to try on a few different sizes to determine which one works best for you.

Is A Bigger Round Brush Better?

The size of the round brush you use can influence your hairstyle and finish. When used to lift and roll your hair while blow-drying, a larger round brush can help create more volume and body in your hair. When used in conjunction with a flat iron, it can also help smooth and straighten hair.

A smaller round brush, on the other hand, can be more precise and provide more control when styling. It is particularly useful for creating curls and waves and styling shorter hair.

Finally, the best round brush size for you will be determined by your personal styling goals as well as the length and thickness of your hair. It may be beneficial to try on a few different sizes to determine which one works best for you.

How Do I Choose The Right Round Brush?

There are a few factors to consider when selecting a round brush:

  1. Size: As previously stated, the size of the brush can have an impact on the style and finish of your hair. When choosing the size of your brush, consider the length and thickness of your hair as well as the style you want to achieve.
  2. Bristle material: Round brushes can be made with a variety of bristle materials, such as natural boar hair, nylon, or a combination of the two. Natural boar hair bristles are gentle on hair and can help smooth and add shine, but they may not be as effective as nylon bristles in creating volume. Although nylon bristles are firmer and more effective at creating volume, they may be more damaging to the hair. Brushes with mixed bristles can provide the advantages of both types of bristles.
  3. Handle material: Round brushes can have plastic, wood, or metal handles. Plastic handles are lighter and easier to grasp, whereas wood or metal handles are more durable.
  4. Some round brushes are oval or cylindrical in shape, while others are flattened or have a pointed tip. The brush’s shape can influence how easily it can reach and style different areas of the hair.
  5. Price: Round brushes range in price from reasonably priced to more expensive options. When deciding on a price point, consider your budget as well as how frequently you intend to use the brush.

It may be beneficial to experiment with a few different options to determine which one works best for you and your hair.

Can A Round Brush Damage Your Hair?

A round brush can harm your hair, especially if used incorrectly or if the brush itself is of poor quality. Here are my top pointers to help you avoid damaging your hair when using a round brush:

  1. Use a heat protectant: Apply a heat protectant product to your hair before using a round brush with heat to help prevent heat damage.
  2. Use the proper temperature: Make sure your blow dryer is set to the correct temperature for your hair type. Using a high heat setting on damaged hair can cause further damage.
  3. Use a ceramic or ionic round brush: These brushes can help reduce frizz and static and are less damaging to the hair than other types of brushes.
  4. Be gentle: When using a round brush, avoid pulling or tugging on your hair, as this can cause breakage. Instead, style your hair with a gentle, sweeping motion.

Avoid using a round brush on wet hair: A round brush is best used on mostly dry hair. When using a round brush on wet hair, it may be more prone to breakage.

Round Brush Size And Thick Hair

Thick hair is amazingly wonderful to have, and many benefits quickly come to mind. For example, styles hold longer and you always have plenty of volume. But your hair is also prone to have tangles, and it takes a lot longer to dry. There are many round brushes on the market but not all of them are best suited for thick hair.

The best ROUND BRUSH will help detangle hair and either eliminate or reduce static and fly-a-ways. Best ROUND BRUSHES also help speed up the drying process. The OLIVIA GARDEN ROUND BRUSH is the best ROUND BRUSH for blowouts for long, thick hair. The OLIVIA GARDEN ROUND BRUSH also comes in an XL long round barrel version.

There are other brushes on the market that are also great for thick hair. But these are the ROUND brushes for thick hair. And that makes a big difference. The goal of this article is to help you save time and money searching for a round brush for thick hair. Otherwise you will most likely buy several before you find the one that can do the job. And the rest will be thrown in the trash or given away to a good home.

According to According to Vanessa Giani Head of training in Paris, “A wooden brush with wild boar bristles is the perfect solution for very frizzy hair as the even spacing of natural bristles helps to properly separate the hair, achieving a straighter finish. In terms of the spacing of the bristles there’s no general rule.

The type of tool you use for thick hair is very important because you want to select the right one, right? Otherwise you will be struggling with your style.

“The important thing to remember is that you want a brush that is going to be able to penetrate thick hair and not every brush can do that.” says Stacey our in-house hair analyst.

Most of the ones that can are going to have nylon bristles due to they are stiffer than boar. And there are ones on the market that have a combination of nylon and boar. These are great options because you get the penetration of nylon and the shine and smoothness of boar. So with boar bristles you get a little more tension or griping power and more polish.

If you have very thick hair and you want to work it out and get that smooth look then you are going to want more tension so you can stretch the hair while applying heat. This is where the grippness of the boar bristles come in to play.

According to Meesh, our in-house hair care product analyst, “If you have medium texture hair then you can get away with using either a porcupine or regular ceramic thermal brush.”

Another feature to look for is the bristle spacing. You want a wider bristle spacing because it’s going to have better penetration. Most of the well known bushes for thick hair are going to have “porcupine” mentioned in their name. This is a clue you can look for while searching for the perfect brush.

If you have medium texture hair then you can get away with using either a porcupine or regular ceramic thermal brush. You have a choice. Lucky you! Wen using the regular ceramic thermal brush with NO boar bristles you will notice that it slips through your hair more easily. It’s not as grippy as the porcupine with boar bristles.

“You will get less texture and less bounce using a boar and more texture more bounce using a ceramic thermal brush. You will be able to visually see the difference. The ceramic thermal will be able to add so much more bounce. But the boar bristles round brush will add more, a lot more, polish and shine. So having a thermal ceramic boar and nylon bush is a good thing and now you know why. “, according to Ed.

Although these brushes may be able to detangle, that is not their primary purpose and they should not be used as such. Also, some of these brushes have boar bristles and boar bristles are to be used on dry hair. Do not use boar on wet hair. By doing so you will most likely cause damage to your hair. If you need to be able to comb thru wet hair or detangle wet hair you should consider purchasing another brush. You need a detangling brush.

What better way to capture a modern classic hairstyle than with a round brush. According to Nicole Contrastano At Pierre Michel Salon, “modernized classic captures every individual’s features, hair, texture and lifestyle.

And lastly, if you use a ceramic brush be careful with the heat settings on your dryer. Thermal brush will retain more heat. These brushes can get extremely hot, so hot they can easily damage your hair and even melt nylon bristles. If it’s hot enough to melt nylon just imagine the damage it can do to your hair. The good thing is that if you have thick hair and it is less susceptible to damage than thin hair. Thick hair can take more heat.

According to Jayne Littler, Hair Stylist at Mason Pearson, “One of the most important things is making sure the heat from the blow dryer is not touching your brush“.

Round Brush Conclusion

  1. It seems most all the plastic brushes are cheaply constructed and parts tend to come off with normal use.
  2. Also handle construction is a concern. With thick hair you are definitely going to be putting more tension on the handle. Handle construction then becomes very important. Too bad you have to spend a lot more to get a good solid one piece handle that does not grab your hair.
  3. Also, all brushes or at least 90% of them that have ball tips all come off. On all these brushes the ball tips come off.
  4. Also, many brushes seem to have a join or a seem where the handle meets the brush part. And as a result, this can catch longer hair. You could end up ripping out your hair. I consider this a bad design and would rather opt for a one piece handle.
  5. And lastly, most handles are grippy where you do not want them. This causes your hair to be pulled. Hair tends to be caught by the handle since it’s so grippy. This of course would be a major concern for longer hair.

Go easy on your hair. At the end of the day that is all you got so take care of it. You hair will thank you later!!!
