But to get the most out of it, you need to know how to use Dyson hair dryer correctly. Whether you are aiming for sleek straight styles, bouncy curls, or flyaway-free finishes, mastering the right settings, attachments, and techniques is the key.
In this guide, you will learn step-by-step how to prep, dry, and style your hair like a professional. You will discover which attachments to use for your hair type, how to navigate the heat and speed settings, and maintenance tips to keep your Dyson performing like new for years to come.
Start with Proper Hair Prep
Before you even plug in your Dyson, proper preparation sets the foundation for faster drying and better results.
Towel-Dry Gently
Begin with clean, freshly washed hair. Use a microfiber towel or an old cotton T-shirt to blot out excess water. Avoid rubbing, which can rough up the cuticle and cause frizz. Gently squeeze or press sections instead.
Apply Heat Protectant
Always apply a heat protectant spray or serum before drying. This shields your strands from thermal damage, especially important even with Dyson’s intelligent heat control. For curly types, add a curl cream or mousse to define shape and reduce frizz.
Section Your Hair
Clip your hair into 4 to 6 sections using duckbill clips. This ensures even drying and prevents you from missing spots. Start with the bottom layers and work upward for maximum control.
Know Your Magnetic Attachments
Dyson’s magnetic nozzles snap on and off in seconds and rotate 360 degrees while attached. Each one shapes airflow for a specific styling goal.
Styling Concentrator (18 mm)
Use for: Precision drying and smoothing. Best with: Round brush blowouts. This narrow nozzle delivers focused airflow, perfect for straightening or creating volume at the roots. Guide it along with a vented barrel brush to smooth each section from root to tip.
Diffuser
Use for: Enhancing curls and reducing frizz. Best with: Curly, wavy, or textured hair. The diffuser’s prongs cradle curls without disturbing their pattern. Flip your head upside down, place sections into the prongs, and dry from the roots up. This boosts volume and definition while minimizing frizz.
Flyaway Attachment
Use for: Smoothing baby hairs and flyaways. Best with: Cold or low heat plus high speed. This attachment leverages the Coanda effect, where airflow wraps around the hair and pulls short strands under longer ones. Hold it 1 to 2 inches from the scalp, wait for hair to lift, then glide slowly down. Rotate 45 degrees using the cool edges to style the back and sides.
Gentle Air Nozzle
Use for: Pre-drying delicate hair. Best with: Fine, thin, or color-treated hair. This nozzle delivers softer, cooler airflow to gently remove moisture without heat stress. Use it first to pre-dry before switching to other attachments.
Smoothing Nozzle
Use for: Polished everyday blowouts. Best with: Medium to thick hair. This nozzle provides uniform, low-speed airflow for a soft, shiny finish. Works well with a vented brush for smooth, bouncy styles.
Wide Tooth Comb Attachment
Use for: Detangling and styling curly hair. Best with: Thick, coarse, or curly textures. This attachment helps distribute airflow evenly while gently separating curls. Use during drying to shape without disrupting curl formation.
Master Heat and Speed Settings
The Dyson Supersonic offers four heat settings and three speed levels, creating 12 combinations for total customization.
Heat Settings Explained
Low at 140 degrees Fahrenheit provides gentle drying for fine or damaged hair. Medium at 160 degrees Fahrenheit is ideal for most hair types. High at 200 degrees Fahrenheit delivers fast drying for thick, coarse hair. Cold shot at 82.4 degrees Fahrenheit locks in style, seals the cuticle, and boosts shine.
Speed Settings Explained
Low provides soft airflow for delicate styling. Medium offers balanced drying for general use. High delivers maximum power for fast drying and flyaway control.
Recommended Settings by Hair Type
Use this table to match your hair type with the right settings:
Fine or thin hair works best with low or medium heat, medium speed, and the Gentle Air or Flyaway attachment. Thick or coarse hair needs high heat, high speed, and the Styling Concentrator or Diffuser. Curly or wavy hair thrives with medium heat, medium speed, and the Diffuser or Wide Tooth Comb. Color-treated hair does well with medium heat, medium speed, and the Gentle Air or Smoothing Nozzle. Straight hair with flyaways responds to low or cold heat, high speed, and the Flyaway Attachment.
Achieve a Smooth Blowout
Want salon-smooth hair at home? Follow this professional technique.
Pre-Dry with Gentle Air
Start with the Gentle Air nozzle, medium heat, and medium speed. Lift roots with a 45 mm vented barrel brush to build volume. Dry each section halfway before switching tools.
Switch to Styling Concentrator
Attach the Styling Concentrator and continue drying. Wrap hair around the brush, roll it down to the ends, and guide the nozzle along with it. This smooths cuticles and adds shine.
Alternate Roll Direction
For natural-looking flicks, alternate the direction you roll the brush. Some sections forward, some back. This prevents a helmet-like finish.
Finish with Cold Shot and Flyaway Tool
After each section, hit it with the cold shot to set the style. Then use the Flyaway attachment on high speed and cold setting. Hold until hair lifts, then glide slowly down. Rotate 45 degrees to style the back without removing the nozzle.
Define Curls and Waves
Enhance your natural texture without frizz.
Apply Product First
Use a curl-enhancing mousse or cream on damp hair. Scrunch gently to encourage curl formation.
Use the Diffuser Upside Down
Flip your head over and dry the crown from underneath. This lifts roots for instant volume. Use medium heat and medium speed.
Dry in Sections
Clip hair into parts. Take small sections, wrap around fingers, and place into diffuser prongs. Hover, do not scrunch, until dry. This preserves curl pattern.
Shake and Separate
Once fully dry, shake out curls with your fingers. For extra definition, apply a tiny amount of oil or serum to the ends.
Add Volume to Fine or Flat Hair
Fine hair needs lift. Here is how to get it.
Pre-Dry at the Roots
Use the Gentle Air nozzle and lift sections with a 35 mm or 45 mm vented brush. Focus airflow at the scalp while pulling the brush upward.
Use Medium Heat and Speed
Avoid high heat, which can weaken fine strands. Stick with medium heat and medium speed for safe, effective drying.
Roll Fringe for Lift
Wrap bangs around the brush and roll backward. This creates subtle root lift without flipping them forward.
Finish with Cold Air
A final blast of cold air sets volume and prevents collapse throughout the day.
Tame Flyaways Like a Pro
The Flyaway attachment is a game-changer for baby hairs.
Use High Speed, Low or Cold Heat
Set to high speed and low or cold heat, depending on hair thickness. Thick hair can handle a touch of warmth. Fine hair should use cold.
Let the Coanda Effect Work
Hold the attachment 1 to 2 inches from the scalp. Wait 2 to 3 seconds for hair to naturally attract to the airflow. Do not rush. Let the physics do the work.
Glide Slowly Down the Shaft
Once lifted, slowly move the nozzle down the hair length. This tucks flyaways under longer strands for a sleek finish.
Rotate to Style the Back
Without removing the nozzle, grip the cool outer edges and rotate it 45 degrees to access the nape of the neck and sides.
Use the Cold Shot Effectively
This is not just a gimmick. It is essential for lasting style.
Lock in Volume and Shape
Press the cold shot button after drying each section. Cold air contracts the hair shaft, sealing the cuticle and locking in smoothness and volume.
Enhance Shine
Finish your entire style with a full cold pass. This boosts shine and ensures your look lasts longer.
Combine with Flyaway Tool
For the smoothest finish, use the Flyaway attachment with the cold shot. The combo delivers maximum smoothing and alignment.
Pair with the Right Brushes
Your Dyson works best with the right tools.
Dyson Vented Barrel Brush (45 mm)
Best for: Long hair, volume, soft waves. Use with the Smoothing or Styling Concentrator for polished blowouts.
Dyson Vented Barrel Brush (35 mm)
Best for: Short to medium hair, fringes, tight curls. Perfect for adding lift at the roots and shaping bangs.
Wide Tooth Comb
Best for: Detangling curly or thick hair during drying. Use the attachment or a standalone comb to separate curls without breakage.
Apply Post-Styling Products Wisely
Finish strong without weighing hair down.
Use a Pea-Sized Amount
Apply 1 to 2 drops of serum or oil to your palms. Rub hands together and gently glide over ends and flyaways. Avoid the roots to prevent greasiness.
Reactivate with Heat
If you used a styling cream that needs heat activation, go over hair lightly with low heat after applying product.
Maintain Your Dyson for Peak Performance
A clean Dyson performs better and lasts longer.
Clean the Filter Monthly
When three white LEDs flash, the filter is blocked. Here is how to clean it.
Remove the filter cover at the base of the handle. Pull out the filter and rinse under warm water. Let it air dry for 24 hours. Never reinsert while damp. Snap it back in and replace the cover.
A clogged filter reduces airflow, slows drying, and strains the motor.
Wipe Down After Use
Use a damp cloth to clean the body and attachments. Never immerse in water.
Store Properly
Keep in a dry place. Avoid wrapping the cord tightly. Coil it loosely to prevent damage.
Avoid Third-Party Attachments
Only use genuine Dyson nozzles. Non-magnetic or ill-fitting attachments disrupt airflow and may damage the motor.
Expert Tips You Need to Know
Follow these professional tricks to get the most from your Dyson.
Section hair for even drying using clips. This ensures you do not miss spots and reduces drying time. Dry roots first by lifting hair at the scalp with a brush and directing airflow there. This creates volume that lasts all day. Use cold shot between sections by hitting each one with cold air before moving on. This sets the style early and prevents heat buildup.
Match brush size to hair length. The 45 mm brush works best for long hair. The 35 mm brush suits short to medium hair. Rotate nozzle without removing by holding the cool outer edges and turning the attachment 45 degrees to style the back and sides seamlessly.
Do not overlap attachments. Ensure full magnetic contact. Misaligned nozzles reduce airflow efficiency. Pre-style with product by always applying heat protectant, mousse, or cream before drying. Dyson enhances your routine. It does not replace prep.
Do not rush the process. Allow each section to dry fully before moving on. Half-dry hair leads to frizz when exposed to ambient humidity. End your styling with a final pass with cold air. It boosts shine and sets the overall look. Clean the filter every month. This single habit keeps your Dyson running at 100 percent.
Troubleshooting Common Issues
Dryer Feels Weak or Slower Than Usual
Check the filter. A clogged filter is the number one cause of reduced airflow. Clean and dry it completely.
Attachment Will Not Stay On
Ensure full magnetic contact. Wipe the connection points on both dryer and nozzle. Avoid using damaged or third-party attachments.
Overheating or Auto-Shutoff
Let it cool down. This usually happens after prolonged use or a blocked filter. Clean the filter and allow 30 minutes to cool.
Noise Seems Louder
This is normal variation. The V9 motor is powerful. If noise increases suddenly, check for blockages or debris in the intake.
