Like many, I’ve struggled with the perfect at-home blowout, only to be left with a tangled mess! Consequently, I often splurge at the salon for that flawless finish. I’ve discovered that my main setback isn’t technique but rather the wrong choice of hairbrush. Using a flat brush is not very helpful in your blow-dry pursuits. You need to invest in the perfect round brush. They come in different diameters and are best for creating volume, achieving curls or waves, and smoothing frizzy hair. With so many choices on the market, selecting the right one can be confusing. Should you choose one with natural or synthetic bristles? Is the ceramic barrel better than the titanium one? We’ve created a list of the best round brushes to help navigate the choices and keep you out of blow-dry bars.

Having the correct styling tools is not just about saving money – it’s also about efficiency. Did you know a recent study indicated that the average woman requires over 24 hours daily to complete all her tasks? A staggering 55 minutes of this is dedicated to morning preparations, with hair styling consuming a significant portion.

Not all round brushes are created equal. Here’s how to choose the best round brush for your hair type and desired style:

  • Barrel Size: Smaller barrels (1 inch) are ideal for curls and short hair, while larger barrels (2 inches and up) smooth and volumize longer hair.
  • Bristles: Natural boar bristles are gentle and distribute heat evenly, while nylon bristles offer more grip and control. Choose mixed bristles for the best of both worlds.
  • Ceramic or Metal Barrel: Ceramic barrels heat evenly and reduce frizz, while metal barrels heat up faster for quicker drying.

How to Blow-Dry Your Hair:

Now, let’s put your best round brush to work with this blow-drying technique:

  1. Prep Your Hair: Apply heat protectant and detangle thoroughly. Towel-dry your hair until it’s about 80 percent dry.
  2. Section and Conquer: Divide your hair into manageable sections using clips.
  3. Brush and Blast: Place the brush at the roots of a section and direct the dryer nozzle downwards. As you dry, rotate the brush and pull it upwards, following the curve of your head.
  4. Repeat and Refine: Continue this process section by section, focusing on drying the roots first for maximum volume.
  5. Finishing Touches: Use the cool setting on your dryer to set the style and add shine. For extra volume, flip your head upside down and blast your roots for a few seconds.

Remember, the brush’s diameter can influence the resulting curl tightness or the volume attained. The smaller one is ideal for shorter hair and styling bangs. The medium-sized brush is perfect for medium-length hair, and the larger diameter is best for longer hair and creating volume or soft waves. Which is the best round brush to help tame your mane? We’ve sifted through the options and compiled the top picks for you. Dive into our list below! Let us know your favorites in the comments.
