Getting a smooth, bouncy blowout at home can be frustrating when a round brush and blow dryer require more coordination than you want to give them. The Wavytalk Blowout Boost 1.5-Inch Ionic Thermal Brush takes a simpler approach by combining a heated round barrel, bristles, adjustable heat, and ionic technology in one styling tool. Its strongest points are the five temperature settings, compact 1.5-inch barrel, and ability to shape already-dry hair into waves, curls, lifted roots, or smoother ends. The main limitation is just as important: this is a thermal styling brush, not a hot-air brush, so your hair needs to be fully dry before you start.
Quick Verdict
Rating: 8.6/10, Recommended with caveats
Best For: Short to medium hair, bouncy waves, defined ends, root lift, and dry-hair blowout styling.
Bottom Line: The 1.5-inch Blowout Boost gives you useful heat control and a manageable barrel for shaping dry hair without juggling a separate round brush. It is less suitable if you need one tool that can dry wet hair and style it at the same time.

What Is the Wavytalk Blowout Boost?
The Wavytalk Blowout Boost is a heated round styling brush built for shaping hair after it has already dried. Unlike a blow-dryer brush, it does not push hot air through the bristles. Instead, the heated 1.5-inch barrel and brush design let you lift, roll, smooth, and bend sections of dry hair.
The 1.5-inch size is especially useful if you have short to medium hair or want a more defined bend than a larger round barrel gives you. You can pull it through a section for a smoother finish, turn the ends inward or outward, lift at the roots, or wrap smaller sections around the barrel for bouncy waves.
Who Should Buy It?
Best For
- You have short to medium hair and want a 1.5-inch barrel for defined movement.
- You want adjustable heat rather than a one-temperature styling brush.
- You normally style dry hair and want root lift, rounded ends, waves, or a polished blowout finish.
Skip If
- You want a tool that dries wet hair while you style.
- You mainly want loose volume on very long hair and prefer a larger barrel.
- You do not want to use a heated styling tool on your hair.
Before You Buy: The Blowout Boost is not a blow dryer. Your hair should be fully dry before you use it. If you want one tool that takes hair from wet to styled, a hot-air brush is a better match.
Five Heat Settings Give You Better Control
One of the strongest reasons to choose this version of the Wavytalk thermal brush is its five-step temperature control. The available settings are 300°F, 330°F, 360°F, 390°F, and 420°F, giving you more room to match the heat to your hair instead of relying on a single high setting.
Wavytalk positions 300°F for softer, fine, fragile, or heat-sensitive hair, while the higher settings are intended for thicker or more resistant textures. A sensible approach is to begin at the lowest setting that can shape your hair effectively and increase only when needed.
This matters because more heat is not automatically better. If your hair responds at 330°F or 360°F, moving straight to 420°F adds unnecessary heat without guaranteeing a better finish.
Pro Tip: Test the brush on a small lower section of your hair first. Start low, check how easily the section takes shape, and raise the temperature only if you need more heat.
Ionic Technology and Frizz Control
The Blowout Boost uses negative ion technology as part of its smoothing system. The feature is designed to help reduce the look of frizz and improve shine while you guide the brush along the hair.
You should still keep expectations realistic. Ionic technology does not override humidity, existing hair damage, or poor preparation. Starting with completely dry, detangled hair and using manageable sections has a major effect on how smoothly the brush moves and how polished the result looks.
Heating System, Barrel, and Handling
Wavytalk uses dual PTC heating elements in this model. The brush reaches its selected temperature in about 30 seconds, so you do not need a long preheat period before starting your routine.
The 1.5-inch barrel gives you more shaping ability than a wider 1.75-inch design. That smaller diameter can help you create tighter bends, more defined waves, and noticeable movement through shorter layers. The tradeoff is that very long hair may take more sections to finish.
At about 0.5 lb, or 238 g, the tool is relatively light for repeated brushing and rolling. Its 79-inch, 2-meter cord also gives you reasonable room to move around a bathroom counter or vanity.
How It Performs in Real Use
For a Smooth Everyday Blowout
For everyday styling, divide dry, detangled hair into smaller sections and guide the brush from near the roots through the ends. A slow, controlled pass gives the heated surface time to shape the section. Turning the barrel slightly as you approach the ends can create a softer, rounded finish.
For Root Volume
Place the brush underneath a section near the crown, lift the hair upward, and then glide through the length. The round barrel makes this easier than trying to create lift with a flat iron. Avoid pressing the hot barrel directly against your scalp.
For Waves and Defined Ends
The 1.5-inch barrel is well suited to more defined movement. You can wrap smaller sections around the brush and rotate as you glide, or turn only the final few inches inward or outward. Letting the shaped section cool before brushing through it can help preserve the bend.
For Second-Day Touch-Ups
You do not always need to restyle your full head. On second-day hair, you can focus on flattened crown sections, face-framing layers, and ends that have lost their shape. This reduces the amount of hair you expose to repeated heat.
How to Use the Wavytalk Thermal Brush Correctly
- Dry your hair completely. This brush is made for dry styling and does not blow air.
- Detangle first. Knots make it harder for the bristles to glide smoothly.
- Apply a heat protectant. Follow the directions on the product you use.
- Choose a conservative starting temperature. Increase the heat only if your hair needs it.
- Work in smaller sections. Large sections are harder to heat and shape evenly.
- Control the barrel near your roots. Use it for lift without pressing the heated surface against your scalp.
- Let curls and bends cool. Avoid brushing them out immediately if you want the shape to last.
Heat Safety and Maintenance
Because this is a heated electrical styling tool, basic heat precautions matter. Use it only as directed, keep the hot barrel away from your scalp and skin, and do not use it on wet or damp hair. Starting at the lowest effective temperature is also a practical way to limit unnecessary heat exposure.
Before cleaning, unplug the brush and let it cool fully. Remove trapped hair from the bristles and wipe the exterior gently rather than using harsh or abrasive cleaners. Store it in a dry place, and avoid wrapping the cord tightly around the tool.
Pros and Cons
Pros
- Five heat settings from 300°F to 420°F give you useful temperature control.
- 1.5-inch barrel works well for defined waves, curled ends, and short-to-medium hair.
- Negative ion technology is designed to help smooth frizz and improve shine.
- About 30-second heat-up keeps preparation time short.
- Universal voltage makes the design more practical for travel when used with the correct plug adapter where needed.
Cons
- It cannot dry wet hair because it has no hot-air function.
- The smaller barrel can require more sections if your hair is very long or dense.
- Getting the best curl or volume may require some practice with section size and rolling technique.
Is It Worth the Price?
The Wavytalk Blowout Boost sits in a practical middle ground between basic heated brushes and more complex multi-attachment styling systems. Its value comes mainly from the combination of five heat levels, ionic technology, dual heating elements, universal voltage, and a 1.5-inch round barrel in one tool.
It makes the most sense if you regularly style already-dry hair and want more shape than a straightener gives you. It is less compelling if your priority is replacing both your hair dryer and styling brush, since you still need to dry your hair separately.
How It Compares to Alternatives
Wavytalk’s Blowout Boost Grande uses a larger 1.75-inch barrel. That version is better suited to medium-to-long hair, softer volume, and smoother blowout shapes, while the 1.5-inch Blowout Boost is the better choice when you want more defined curls or bouncy waves.
Wavytalk also offers its Heatwave Pro range for buyers who want a more expandable styling system or additional accessories. The standard Blowout Boost makes more sense if you prefer a straightforward fixed 1.5-inch brush without paying for features or attachments you may not use.
Frequently Asked Questions
Can you use the Wavytalk Blowout Boost on wet hair?
No. The Blowout Boost is a heated styling brush for fully dry hair. It does not blow air, so dry your hair completely before using it.
How long does the Wavytalk thermal brush take to heat up?
Wavytalk states that the Blowout Boost heats in about 30 seconds. Wait until it reaches your selected setting before styling for more consistent heat.
Which temperature should you use?
The settings are 300°F, 330°F, 360°F, 390°F, and 420°F. Start with a lower temperature, especially on fine, fragile, damaged, or color-treated hair, and increase only when your hair needs more heat to hold the shape.
Is the 1.5-inch barrel good for long hair?
You can use it on longer hair, but the 1.5-inch size is aimed more toward short-to-medium hair and defined waves. If your priority is soft volume across medium-to-long hair, Wavytalk’s larger 1.75-inch version may be easier to work with.
Does it replace a blow dryer?
No. It shapes, smooths, curls, and adds volume to dry hair, but it cannot dry wet hair. You still need to air dry your hair or use a separate dryer first.
Can you travel internationally with it?
The Blowout Boost supports universal voltage. You may still need the correct physical plug adapter for the outlet used at your destination, so check the destination’s plug type before traveling.
How should you clean the thermal brush?
Unplug it and allow it to cool completely first. Remove trapped hair from the bristles and wipe the tool gently with a soft, slightly damp cloth without using harsh cleaners or soaking the electrical components.
The Bottom Line
The Wavytalk Blowout Boost 1.5-Inch Ionic Thermal Brush is a strong fit if you want adjustable heat, a smaller round barrel, and a simple way to add waves, root lift, or polished ends to fully dry hair. Skip it if you need a wet-to-dry hot-air brush or prefer the looser volume of a larger barrel. Its five heat settings, quick warm-up, ionic system, and 1.5-inch design make it a practical styling tool as long as you understand that drying your hair remains a separate step.
