As someone with fine, straight, and sleek hair, giving my hair volume is a priority. However, I’ve often struggled with getting my hair to stay voluminous, with it typically going flat within a few hours.
I’ve always loved the ’90s blowout. Bouncy, soft waves with lots of volume at the roots and plenty of shine are flattering, sophisticated, and chic. This trending hairstyle gives hair lots of body and movement, and it looks great on everyone.
The Wavytalk Blowout Boost thermal brush promises to deliver effortless volume, waves, and bounce to your locks. This heated round brush went viral on TikTok and has gained a tonne of positive reviews.
But is the Wavytalk Blowout Boost worth the hype? In this review, I share my experience of using the thermal brush, including how easy it is to use, whether it damages hair, and whether it’s worth the price.

How to use the Wavytalk Blowout Boost
The Wavytalk Blowout Boost is a versatile styling tool. You can use it to straighten your strands, add some volume at the roots, flick out the ends, or create soft, bouncy waves.
Always use this thermal brush on dry hair; it’s not designed for use on damp hair.
Follow these easy steps to style your hair effortlessly:
- Before styling, spritz your hair with a heat protectant spray to avoid any damage.
- Select the appropriate temperature. Press and hold the power button to turn on the device. Cycle through the 5 temperature settings by pressing the power button repeatedly:
- 150 °C – Ideal for fine or damaged hair
- 165 °C – Suitable for normal or slightly thick hair
- 180 °C – Best for thick or coarse hair
- 200 °C – For very thick or unruly hair
- 215 °C – Maximum heat for ultra-resistant hair
- Use the included sectioning clips to divide your hair into manageable sections. This ensures even styling.
- Begin styling.
- For straight styles: Starting at the roots, place a small section of hair between the bristles. Slowly glide the brush down the length of your hair to smooth and straighten.
- For voluminous styles: Wrap a small section of hair vertically around the brush, starting from the roots. Twist and glide the brush down to the ends to add volume and body.
- For curls or waves: Wrap a section of hair around the brush, hold briefly, then release for soft curls or waves.
- Once all sections are styled, use your fingers or a wide-tooth comb to gently separate curls or waves for a natural look. Apply a light hairspray if desired to set your style.

Honest review
The Wavytalk Blowout Boost is an excellent styling tool that’s versatile, affordable, and surprisingly easy to use.
This thermal brush is the lightest heated styling tool I’ve ever used, which makes styling hair so easy, as you don’t get armache from holding the device! The sleek pink design is also cute, and the outer parts of the device don’t get super hot, so it minimises the risk of burning yourself.
I found the device very easy to use. I’ve used it twice. The first time was to add volume throughout my hair and flick out the ends for a chic look, and the second time was simply to straighten my hair and add volume throughout. Both times, after a little practice to get the movement of the brush right, I got the hang of it quickly.
Here’s how my hair turned out when I flicked the ends out:
I love how my hair turned out! I got a lot of volume into the roots, which made my hair look thicker, fuller, and like it had more body. Most importantly, my hair stayed voluminous all day. Normally, my hair drops within 3 hours of styling it. After using the Wavytalk Blowout Boost, my hair lasted all evening – around 6 hours – and even had volume the next day. So impressed!
It’s important that you use a heat protectant spray when using the Blowout Boost, though, as the bristles get quite hot, so they could damage your hair if you’re not careful.
The only downside to this thermal brush is that hair can get tangled or caught on the bristles. Thankfully, it’s easy to untangle any hair that gets caught in between the bristles by simply unwinding the device in the opposite direction to how you styled your strands or gently pulling your hair out of the bristles. However, I’d recommend using a smoothing or de-frizzing hair product prior to using the device, especially if your hair is prone to tangling easily. This helps avoid the issue altogether.
Rating: 5 stars
This thermal brush is totally worth the hype and money. It’s affordable and versatile, and I can see this tool becoming a staple in my daily haircare routine.
If you want a device to add volume to your hair, give you the ’90s blowout look, or simply straighten or wave your strands, the Wavytalk Blowout Boost is a must. You won’t be disappointed.
