This Viral Hair Dryer Dried Hair Faster Than All Others Our Lab Tested (2025)

Wattage: 1,600 | Attachments: 2 concentrators, diffuser, flyaway attachment, gentle air attachment | Number of settings: 3 speed; 4 heat | Weight: 1.9 lbs. | Cool shot button: Yes | Ion technology: Yes

With a powerful motor in its handle, Dyson's innovative dryer has proven to be game-changer that's worth the splurge. It dried hair faster than any model in the history of GH Beauty Lab hair dryer testing. The dryer comes with five magnetic attachments to suit different hair types, including two concentrators, a diffuser, a flyaway smoother and a gentle air attachment.

The tool is also a favorite among professional hairstylists. "It's pricey but worth it," Alvarez said. "The technology is so advanced, the cord is so long and its three heat and airflow settings make it so efficient. It dries hair quickly, and the smoothing attachment gets rid of frizz without needing a styling product, making blowouts last longer."

Lab test results: The model dried an eight-inch hair sample in just 54 seconds and delivered strong airflow in Lab assessment. Lab experts also like that it has a long cord, helping you reach distant outlets or mirrors and avoiding awkward positioning while styling. A few drawbacks: It is on the heavier side, lacks a cord tie and has buttons that can be tricky to reach.

What testers say: Consumer testers with various hair types (straight to curly) and lengths (short to very long) told us they loved this dryer. One tester said, "On the most humid days, it smoothed my hair faster than any dryer I've used." Another added, "The air pressure was great, and it dried my hair faster than usual."

If you're willing to spend more, note that Alvarez is a fan of the brand's Pro Artist Black Gold Ionic Hair Dryer.

What testers say: Testers especially loved its smaller, easy-to-store size and reported that it reduced frizz. "This dryer left my hair with less frizz and more shine," one tester said. "It was easy to use and small enough to store anywhere." Another added, "It dried my hair much faster than usual."

Strong yet gentle, Bio Ionic’s hair dryer proved to be a great match for damaged hair in GH Beauty Lab testing.

Lab test results: The tool had the lowest air temperature at its highest setting, yet still dried hair quickly. Experts found it comfortable to hold, with easy-to-use attachments and well-placed control buttons, including a convenient cool shot button.

Though the model was loud in Quiet Mark sound tests and is pricey, it comes with a 10-year motor warranty and a storage bag. Note that it lacks a diffuser, making it less suitable for curly hair.

What testers say: One tester praised this model as "sleek-looking" with a "balanced weight and size that’s not too heavy or big but feels powerful." Two others added, "I like that it has three temperature settings," and "it worked really well."

Lab test results: Evaluations found that the tool dried hair quickly due to its strong airflow and heat, but didn't burn or irritate the scalp. Easy to hold and operate, it also earned a perfect score for ease of maneuvering attachments and has a generously long cord.

The GH Beauty Lab has been testing hair tools, including hair dryers, hair dryer brushes and travel hair dryers, for over a decade. In the most recent test, our scientists evaluated 41 hair dryers over eight weeks (that's 320 hours of hands-on testing!), analyzing 2,244 data points to identify the top-performing models. Hair dryers are tested as follows:

✔️ In the Lab: GH Beauty Lab experts test hair dryers at various price points and power levels (1,500 to 2,000 watts) in the Lab, measuring drying speed on standardized human hair samples, airflow force, air temperature, weight, surface temperature and cord length.

✔️ On consumer testers: Consumer testers with a range of hair types (thin, medium, thick) and textures (straight, wavy, curly, coily) assess them at home for ease of use, scalp and hair damage, and appearance of hair after drying.

✔️ For noise emission: Noise emission is also measured by third-party certifier Quiet Mark, which issues a star rating (1 star for Poor/Loud, 2 stars for Average, 3 stars for Good/Quiet) based on sound level tests.

Wattage

• A hair dryer's wattage determines its power.
• 1,875 watts is the most common hair dryer wattage.
• The GH Beauty Lab recommends a range between 1,500 and 2,000 watts for best results on all hair types.

Attachments

• Attachments can significantly improve different hair textures by altering the air flow.
  
• Diffusers and concentrators are the most common attachments, and may be included with your dryer or sold separately.
• Diffusers are ideal for curly hair as they reduce frizz, define curls and add volume by gently circulating air to the hair ends.
• Concentrators focus the hair dryer's airflow for smooth, sleek styles. Broad, extended nozzles dry thick, long hair faster, while short, narrow ones help tame curly or frizzy hair for a sleek blowout.

Heat & Speed Settings

• Adjustable settings let you customize the level of heat and power to suit your hair type and preferences.
• Our top-tested hair dryers all have a cool-shot button to close the cuticle, lock in the style and prevent frizz after drying.

Weight & Design

• In testing, we take each model's weight into account, since a too-heavy hair dryer can affect ease of use.
• Our scientists also measure the length of its cord, since a longer hair dryer cord offers more flexibility.
• We assess noise level, because a loud dryer can be uncomfortable to use, especially for extended periods.

Safety Certification

• Check for safety verification emblems like ETL (Electrical Testing Laboratories), UL (Underwriters' Laboratories) or TUV or SUD (both part of the Technical Inspection Association) on the packaging.
• These certifications ensure the dryer was tested for safety and met requirements.

Is a ceramic or ionic hair dryer better?

Ionic technology offers visible benefits and is ideal for curly hair prone to frizz and flyaways, says GH Beauty Lab Director Sabina Wizemann, noting that it reduces static and leaves hair smoother. "In testing, it is easy to see effects when you have ionized technology switched on and off," she explains. "Static builds up when you blast air without an ionizer, and with it, the hair is more aligned and appears shinier."

On the other hand, many hair dryers advertise technologies like ceramic, tourmaline or far-infrared radiation, but our testing has found these aren't essential. While research exists, there's little data on their specific benefits in hair dryer design.

What's the best hair dryer for my hair type?

When choosing the best hair dryer for your hair type, focus on finding one with customizable settings. Here are general guidelines for different hair types:

• Curly hair (3a to 4c types): Opt for an ionic dryer with attachments. "A diffuser is essential for embracing natural texture, and a narrow nozzle helps smooth the hair," Wizemann says.
• Thin hair: Look for a dryer with low heat settings to prevent damage. "High heat is unnecessary unless specific styling requires it," she advises.
• Thick or long hair: Choose a dryer with higher wattage for stronger airflow and heat. "This is ideal for styling thick, dense or long hair," Wizemann says.
• Hair extensions: Standard hair dryers work well for both synthetic and real extensions, Cleveland notes.

Which hair dryer is least damaging?

Minimizing hair damage is actually more about the dryer's features and how you use it. "Using the correct heat settings for your hair type is more important than the dryer's technology," Wizemann says. Generally, lower heat generally causes less damage, but since all hot tools can damage hair, it's essential to protect strands. "Always prep hair with a leave-in styling product that provides heat protection before blow-drying," to form a protective barrier against heat, Alvarez advises.

What is the best way to blow dry hair?

Here are celebrity hairstylist and Kerasilk Brand Ambassador Harry Josh's tips for a bouncy DIY blowout:

• Apply product: Work your leave-in styling product through damp hair from roots to ends, then comb for even distribution.
• Section and start: Divide hair into four parts and dry one at a time. Use the dryer's nozzle to focus airflow while lifting strands with your fingers for volume at the roots.
• Use a brush: Wrap a 1-inch section around the brush and run the nozzle down the hair shaft as you pull the hair taut. Repeat until each section is fully dry.
