Drying your hair can often feel like the longest part of a hair-care routine. After washing and conditioning, you still need to spend several minutes using a conventional hair dryer before your hair is ready for styling.
The Laifen Swift 4 Hair Dryer takes a different approach. Its high-speed 115,000 RPM brushless motor produces airflow of up to 23 m/s, while its temperature-control system monitors heat 1,000 times per second. Laifen says the Swift 4 can dry mid-length hair in around 90 seconds under its testing conditions.
The Swift 4 also adds a Nourishing Mode designed to distribute hair oil through the Nourishing Nozzle. The nozzle turns the oil into a fine mist, while the mode maintains a controlled 58°C airflow.
In this guide, we’ll explain how to connect the Swift 4 to the Laifen app, customize its settings, use the Nourishing Nozzle, choose the right drying mode, and maintain the dryer.
Part 1: Connect the Laifen Swift 4 to the App
The Swift 4 can be used independently using its physical controls. However, connecting it to the Laifen app gives you additional control over your drying preferences.
Step 1: Install the Laifen App
Download and install the Laifen app from the Apple App Store or Google Play Store.
Make sure your phone is running a current version of the app before starting the setup.
Step 2: Turn On Bluetooth
Enable Bluetooth on your smartphone.
Depending on your phone and operating-system version, the app may request additional permissions during setup. Allow the permissions required for device discovery and connectivity.
Step 3: Turn On the Swift 4
Plug the dryer into a suitable power outlet and switch it on.
Keep your smartphone close to the dryer while pairing to make the setup process easier.
Step 4: Add the Dryer
Open the Laifen app and look for the option to add a new device.
Tap + Add Device and wait for the Swift 4 to appear.
Select the dryer when it is detected.
Step 5: Complete Pairing
Follow the instructions displayed in the app to complete the connection.
Once paired, the Swift 4 should appear within the app, allowing you to access its available controls and settings.
Step 6: Customize Your Settings
Open the Swift 4 from the app and explore the available temperature, airflow, and care settings.
You can adjust the dryer according to your hair type and preferred styling routine.
If the Swift 4 isn’t detected: update the Laifen app, make sure Bluetooth is enabled, keep the phone close to the dryer, and restart the pairing process.
Part 2: How to Use the Nourishing Nozzle
One of the Swift 4’s standout features is its Nourishing Mode.
Laifen’s Nourishing Nozzle is designed to disperse hair oil into micron-sized droplets so it can be distributed more evenly during drying. The dedicated Nourishing Mode uses a controlled 58°C airflow.
Step 1: Prepare the Nourishing Pod
Add the recommended amount of hair oil to the Nourishing Pod.
Laifen currently recommends applying 2–3 pumps of hair oil to the pod before use.
Step 2: Insert the Pod
Place the prepared pod into the Nourishing Nozzle.
Make sure it is seated correctly before attaching the nozzle to the dryer.
Step 3: Attach the Nozzle
Attach the Nourishing Nozzle magnetically to the front of the Swift 4.
Adjust its position so the airflow is directed toward the section of hair you are working on.
Step 4: Activate Nourishing Mode
Select Nourishing Mode using the dryer’s controls or through the app if the feature is available there.
For the recommended routine, Laifen suggests drying the hair to around 80% before attaching the Nourishing Nozzle and activating Nourishing Mode.
Work through your hair in sections to distribute the airflow and hair oil evenly.
Tip: Follow the instructions supplied with your specific Swift 4 and hair-oil pod. Avoid applying more oil than recommended.
Part 3: Choose the Right Temperature Mode
The Swift 4 offers multiple temperature modes designed for different drying and styling requirements. Laifen currently lists six temperature modes, including Cold, Warm, Hot, Temperature Cycling, Nourishing, and Child modes.
| Mode | Best For |
|---|---|
| Cold | Finishing a hairstyle and cooling the hair |
| Warm | Everyday drying and gentler styling |
| Hot | Faster drying of thicker or longer hair |
| Temperature Cycling | Alternating between warm and cool airflow |
| Nourishing | Distributing hair oil through the Nourishing Nozzle |
| Child | A gentler setting designed for children |
The Swift 4 also provides two airflow speeds, giving you additional control over how aggressively you want to dry or style your hair.
Part 4: Understanding the Swift 4’s Temperature Control
Heat management is one of the key features of the Swift 4.
According to Laifen, its Smart Temperature Control system checks airflow temperature 1,000 times per second and adjusts the heat accordingly. The goal is to provide fast drying while reducing unnecessary heat exposure.
This makes it easier to switch between faster drying and more controlled styling without relying on a single high-heat setting.

Is the Laifen Swift 4 Worth It?
The Laifen Swift 4 is aimed at users who want more than a basic hair dryer.
Its combination of a 115,000 RPM motor, 23 m/s airflow, multiple temperature modes, smart temperature monitoring, and Nourishing Mode makes it particularly interesting for people who want faster drying and more styling control.
However, it may be unnecessary if you already have a basic dryer that meets your needs or if your hair dries quickly without much styling.
The Nourishing Nozzle is the feature that makes the Swift 4 stand out from a conventional high-speed dryer. Instead of treating drying and hair-oil application as completely separate steps, it combines them into a single routine.
The dryer can also be used without the app, making the app more of an optional customization tool rather than a requirement.
Final Verdict
The Laifen Swift 4 combines high-speed drying with temperature control and an optional nourishing treatment. Its 115,000 RPM brushless motor, 23 m/s airflow, and 1,000-times-per-second temperature monitoring make it a feature-rich alternative to conventional hair dryers.
If you want a faster drying routine with additional styling and hair-care options, the Swift 4 is worth considering. If you simply need a basic dryer for occasional use, its premium features may be more than you need.
Before purchasing, check Laifen’s local product page for the current price, voltage, included accessories, warranty, and available features in your region.
