Top 5 Mistakes to Avoid When Using a Hot Thermal Brush

Using a hot thermal brush can transform your hairstyling routine, making it faster and more effective. However, like any styling tool, there are certain techniques and practices to be mindful of if you want to achieve that salon-quality look without damaging your hair. With my years of experience working in the hairstyling industry, I've seen it all – from minor slip-ups to major mishaps. Here, I’ll share the top five common mistakes people make with hot thermal brushes and how to avoid them to keep your hair looking gorgeous and healthy.

1. Not Sectioning Hair Properly

One of the biggest mistakes I see is skipping the sectioning step. When you're in a hurry, it’s tempting to grab large chunks of hair, but it makes styling uneven and reduces the brush's effectiveness. The B.R.U.S.H 30/40 works best on small sections, ensuring each strand receives the full benefit of the oils and even heat distribution.

How to Avoid It:

Divide your hair into manageable sections based on thickness and length. If you have medium to long hair, use the Size 40 of B.R.U.S.H 30/40, and for short to shoulder-length hair, go for the Size 30. Start from the back, moving to the front for consistent results.

2. Choosing the Wrong Heat Setting

Why the Right Temperature is Key
Not all hair types respond to heat in the same way. If you’re using a hot thermal brush, understanding which heat setting suits your hair type is crucial. Too high, and you risk causing dryness and breakage; too low, and you may not see the desired results.

Setting for Your Hair Type

Fine or damaged hair generally requires lower heat settings (around 150-160°C), while normal to thick hair can handle higher temperatures (up to 180°C). Thermal brush, like our B.R.U.S.H 30/40, come with a single heat setting of 180°C, making it ideal for a wide range of hair types, but always take caution based on your unique needs. If you're worried about heat, start with a lower setting if your device allows and test on a small section of hair.

3. Incorrect Brushing Techniques

Using Too Much Pressure
A common mistake people make is applying too much pressure when using their thermal brush, assuming this will give smoother results. In reality, pressing too hard can stress your hair strands and even lead to tangling or breakage.

The Right Technique
Instead, gently glide the brush down each section of hair in a smooth, controlled motion. Divide your hair into manageable sections (the thicker your hair, the smaller the sections should be). Start at the roots and pull the brush slowly down to the tips. This allows the heat to distribute evenly, giving a more polished finish. If your goal is to add volume, lift each section at the root and roll the brush upward as you style.

Styling Mistake: Going Too Fast or Too Slow
Rushing the process won’t give your hair the time it needs to properly shape. However, moving too slowly can expose your hair to excessive heat. Find a balance – around 2-3 seconds per pass – for an even, smooth finish.

4. Not Cleaning Your Thermal Brush Regularly

Why Regular Cleaning is Essential
Over time, product build-up, oils, and hair strands can accumulate on your thermal brush, which can affect its performance and even lead to uneven heating. A dirty brush can’t glide smoothly and may tug on hair, resulting in unnecessary breakage.

How to Clean Your Hot Thermal Brush
Start by unplugging and allowing it to cool completely. Remove any loose hair strands with a soft brush or comb. Then, use a soft, damp cloth to wipe down the bristles, being careful not to let water enter the device. For stubborn residue, a little rubbing alcohol on a cotton swab can work wonders. Aim to clean your brush every few uses, depending on how often you style your hair and the products you use.

Pro Tip: Make a habit of deep-cleaning your hot thermal brush once a month. Regular maintenance will not only extend its lifespan but also ensure optimal styling results each time you use it.

5. Ignoring the Natural Shape and Needs of Your Hair

Working Against Your Natural Texture
One of the most common mistakes I see is people trying to make their hair do something it naturally resists. For example, if you have very curly or coarse hair, trying to straighten it with a single pass of a thermal brush can lead to disappointment.

Embrace Your Hair’s Unique Qualities
If you have naturally curly or wavy hair and want to smooth it out, try to work in smaller sections and use a thermal brush with ion technology to reduce frizz and static. I often recommend pairing a hot thermal brush with a quality blow-dry cream or styling lotion that matches your hair texture. This helps create a base that the brush can work with rather than against. The ion technology in products like B.R.U.S.H 30/40 can help manage static and frizz, especially for thick or coarse hair types.

Avoid Overstyling
Less is more when using a hot thermal brush, especially if you use other heated tools like flat irons or curling irons regularly. Overstyling can dry out your hair, making it more prone to damage. Using a thermal brush a few times per week is generally safe for most hair types, but if your hair feels dry or brittle, give it a break and opt for a deep-conditioning treatment.

Final Thoughts

Using a hot thermal brush can make hairstyling at home feel effortless and elevate your look with minimal effort. By avoiding these common mistakes, you’ll not only protect the health of your hair but also achieve better styling results. Whether you’re using a product like the B.R.U.S.H 30/40 or another thermal brush, keep these tips in mind for a flawless, salon-quality finish.

Remember, your hair is as unique as you are, and understanding its needs is the first step toward achieving the perfect style. Happy styling, and here’s to healthier, beautifully styled hair!
