Drying your hair is usually a big part of the hair styling routine, which is why many hair care guides and salons separate the washing and conditioning steps from the drying. You wash, you condition, you towel off, you apply oil, then you wait. And after that, you can spend several minutes blasting all of it with heat from a conventional hair dryer.
The new Laifen Swift 4 Hair Dryer cuts the drying time down to roughly a minute and a half thanks to its super-fast 115,000 RPM brushless motor. But, more importantly, it combines drying with conditioning, an essential part of hair care, thanks to a Nourishing Nozzle that diffuses essential oil into the hair.
Here’s how to pair the Swift 4 with the Laifen app, configure its various temperature and care modes, use the Nourishing Nozzle without making a mess, and keep the filter clean so the motor keeps performing. If you haven’t already, you can use this link to get your Laifen Swift on a discounted price.
Part 1 – Start Using the Swift 4 With the Laifen App
The Swift 4 can work standalone by allowing you to swap between modes with buttons. But true customization starts with the app that stores profile settings.
Step 1. Install the Laifen app from the Apple App Store or Google Play.
Step 2. Turn on Bluetooth on your phone. The app will request Location services, but you can ignore that.
Step 3. Plug in the dryer and switch it on. The Swift 4 needs to be working for the app to detect and add it, and it needs to be relatively close to the phone.
Step 4. In the app, tap on “+ Add Device” and wait until the dryer appears on screen. It should be named “Swift 4.”
Step 5. Follow the on-screen prompts to confirm the connection. After this, the dryer should appear on the home screen with a status on whether it’s running.
Step 6. Tap on the device to customize its settings and modes.
If the dryer doesn’t appear, update the app to the latest version and retry the connection process.

How to Set Up Nourishing Mode and Load the Nourishing Nozzle
The Nourishing Nozzle has a slot for a pod that you fill with your own essential oil. The dryer breaks that oil into a micron-sized mist to carry it with the airflow, while the steady 58°C temperature helps it permeate into hair strands.
Step 1. Add a bit of essential oil into the Nourishing Pod (as per instructions).
Step 2. Slot the pod into the Nourishing Nozzle.
Step 3. Attach the nozzle to the dryer. It should click securely into place and can be rotated to adjust the airflow direction.
Step 4. Select “Nourishing Mode” on the handle or in the app. Dry the hair as you normally would, working from root to tip. The Nourishing Mode should be set to last three minutes, but you can customize it via the app.
How to Pick the Right Temperature Mode for Your Hair Type
The Swift 4 Hair Dryer has several temperature and care modes, which can all be adjusted using the app or via the LED ring and physical controls on the dryer. Behind the scenes, the dryer uses a smart temperature control system that samples the heat 1,000 times per second and adjusts power in real time to maintain the optimal temperature.
| Mode | LED ring color | Best for |
| Cold | Blue | Setting a style, cooling the scalp, finishing a blowout |
| Warm | Orange | Everyday drying on fine or damaged hair |
| Hot | Red | Thick or very long hair |
| Temperature Cycling | Rainbow | Alternating heat and cool air to reduce strand damage |
| Nourishing | Purple | Spraying the essential oils through the Nourishing Nozzle |
| Child | Yellow | Lower heat and gentler output for kids |
