Having the right brush is key to banishing bad hair days. With a round brush, you can lift your hair at the roots, smooth out sections, and create texture while you’re blow-drying it — which means if you want to add volume, body, and even waves or curls to your hair, a round brush is the right tool.
A round brush is exactly what it sounds like: instead of having a flat, paddle-like shape, the head of the brush is round and features bristles all the way around. The design allows you to wrap your hair around the brush so you can add lift or soft curls as you dry your hair. It can also help hold your hair taut while you blow-dry it to help straighten and smooth it. Because they’re extremely effective at adding volume to hair, round brushes are especially helpful if you have fine or thin hair.
There are so many round brushes available that finding the right one can be tricky. It means choosing the right size, deciding between natural and synthetic bristles, determining the best barrel material, and choosing what other features would provide the most benefit to your hair.
Round brushes are available with barrels in a variety of sizes. The size for your styling needs typically depends on how long your hair is. Individuals with longer hair require a larger round brush than those with shorter hair.
Like all hair brushes, a round brush can have either natural or synthetic bristles. When you’re choosing a brush, take your hair type into account to determine what type of bristles will work.
Natural bristles are made from animal hair. In most cases, they use boar bristles, which are extremely soft and gentle on the hair. A natural bristle round brush is extremely effective in pulling your hair’s natural oils down to the ends of your hair from the roots, so your locks look extremely shiny and smooth. Because they’re gentler on the hair, they don’t cause as much breakage, either. Natural bristle brushes are usually more expensive.
A round brush with natural bristles is ideal for individuals with straight, fine, wavy, curly, thick, and damaged hair because it reduces breakage and cuts down on frizz.
Synthetic bristles are typically made from nylon or plastic. They’re extremely effective for detangling your hair and usually don’t produce as much static as a natural bristle brush. They’re usually more affordable, though they aren’t as gentle on the hair and may cause damage.
A synthetic bristle round brush is best for thick, coarse hair that’s prone to knots and requires frequent detangling. It can also help add more bounce to curly and textured hair when you’re blow-drying it.
You can find some round brushes that feature a combination of natural and synthetic bristles. These models are less expensive than natural bristle brushes but more expensive than synthetic options. However, they’re able to provide smooth, shiny hair like a natural bristle brush while detangling with ease like a synthetic brush.
Natural/synthetic combination round brushes work for nearly any hair type but are especially effective for grooming long or fine hair.
A round brush’s barrel material plays a significant role in how effective it is for heat styling. All materials are heat-resistant, but some retain heat better than others to really lock in your hairstyle. You can choose from several different materials:
Like hair dryers, some round brushes feature ionic technology in their barrels. That means they’re able to add negative ions to your hair as you blow-dry to reduce frizz and static. As a result, your hair looks smoother and shinier — which can be particularly helpful if you have thick, coarse, or textured hair.
Round brushes with ionic technology can also cut down on your drying time. This allows you to get ready faster, and it reduces your hair’s exposure to heat (and possible damage).
It’s easy for your hand to get tired when you’re blow-drying your hair with a round brush. Models with ergonomically designed handles are easier to hold and can help prevent hand fatigue. Opt for a brush with a contoured gel grip for the most comfortable handle.
Some round brushes feature a vented design. This means their barrel has spaces or vents between the bristles that allow the air from your blow dryer to pass through. A vented brush can help cut down on drying time, but it doesn’t always provide the smoothest results, so it’s best if you only want a rough blow out.
Round brushes vary in price based on the type of bristles, barrel material, and size of the brush. Brushes range from $4 to $185.
The most affordable round brushes have synthetic bristles. Those with metal barrels usually range from $4 to $15, while those with wooden, ceramic, or tourmaline barrels typically cost between $15 and $38.
In this range, round brushes usually feature ionic technology in both the bristles and the barrel. These models range from $8 to $72.
The most expensive round brushes feature natural bristles. Those with metal barrels range from $10 to $30, while those with wooden, ceramic, or tourmaline barrels typically cost between $17 and $185.
A. If your hair gets tangled around your round brush frequently, it usually means you’re using the wrong size or you’re wrapping sections that are too large around it. Long hair can easily get tangled if you use a round brush that’s too small because you need to wrap your hair around it too many times. If you’re wrapping sections around the brush that are larger than two inches, you’re also more likely to experience tangles.
A. Use your fingers or a comb to remove the hair from your round brush after each use. If the hair is caught, use scissors to cut it free. Once every month, clean the brush of any oils, dirt, and product build-up with shampoo and warm water. You can scrub the barrel with a clean toothbrush to remove any trapped dirt. Be sure to rinse the brush well and allow it to air dry thoroughly afterward.
A. It really depends on the type of curls you want to create. If you prefer large, loose curls or waves, you’ll want a brush with a larger barrel. If you prefer tight, ringlet curls, you’ll want a brush with a smaller barrel. You may actually want to have round brushes in multiple sizes so you can change the look of your curls based on the style you’re creating.
