FrediTech verdict at a glance
Laifen’s September 2026 beauty-tech expansion joins the Swift 4 hair dryer with the new AutoCurl styler and Glowy smart mirror. Swift 4’s unusual feature is a nozzle that can diffuse a user-selected hair oil or serum during drying; AutoCurl uses a dual chamber and resistance detection; Glowy adds radar-based presence sensing and remembers lighting preferences. The ecosystem is inventive, but price, worldwide availability and independent hair-care testing remain incomplete.
Most practical product today: Swift 4, because its core dryer specifications and US product page are live. Most important caution: cosmetic and hair-condition claims depend on product choice, hair type and technique; they are not medical outcomes.

What Laifen launched in September 2026
Laifen announced the three-product beauty routine in the United States on September 1. Swift 4 is positioned as the fourth generation of its high-speed dryer line. AutoCurl expands the company into automated styling, while the 8.5-inch Glowy mirror is scheduled to become available on September 4. At publication, complete prices, international dates and retailer lists were not available for the entire trio.
| Product | Headline feature | Main buying question |
|---|---|---|
| Laifen Swift 4 | 115,000rpm motor, six heat modes and oil/serum-diffusing nozzle | Does the nourishing system improve results without adding mess? |
| Laifen AutoCurl | Dual curling chamber with direction detection and resistance pause | How consistently does it handle different lengths and textures? |
| Laifen Glowy | 8.5-inch lighted mirror with 24GHz radar presence sensing | Is remembered lighting worth the price and counter space? |
Swift 4: faster airflow plus a “nourishing” nozzle
Swift 4 uses a motor rated at 115,000rpm and airflow quoted at up to 23 metres per second. Those figures describe the motor and air speed, not a guaranteed drying time. Hair density, length, starting moisture, nozzle distance and heat selection all matter. Independent tests should measure drying speed alongside temperature stability, noise, weight and frizz.
The most distinctive attachment accepts a pod filled with the user’s own compatible hair oil or serum and disperses it while drying. This could make product application more even and save a step. It also creates questions about viscosity, residue, cleaning, inhaled mist and whether every formula is suitable for heated diffusion. Buyers should use only substances and quantities permitted by Laifen’s final manual rather than experimenting with fragrance oils or skin products.
Six temperature modes provide more control than a basic hot/warm/cool switch. Lower heat can be useful for fine, damaged or colour-treated hair, while higher settings can shorten drying on dense hair. No dryer can eliminate heat damage: keep it moving, maintain distance and stop once hair is dry.
AutoCurl: automation with resistance detection
AutoCurl uses a dual-chamber design intended to identify the section’s origin and choose a curl direction. Laifen also says the mechanism pauses when it detects resistance. That safety response is important for an automated tool that draws hair into a chamber, but it does not replace proper section size, detangling or supervision.
The relevant test is not whether AutoCurl can create one polished promotional curl. Reviewers should compare left/right consistency, time per section, heat recovery, snagging, performance on shorter layers and coily or textured hair, and how easily the chamber can be cleaned. Users with extensions should also confirm compatibility with their stylist and the appliance instructions.
Glowy smart mirror: convenience without a camera
Glowy is an 8.5-inch illuminated mirror that uses a 24GHz radar sensor to detect presence. Laifen says it can turn on as the user approaches and remember preferred light and temperature settings. Radar sensing can provide hands-free activation without requiring a camera, which is a privacy advantage for bedrooms and bathrooms.
Before buying, check brightness range, colour-rendering accuracy, magnification, power source, battery runtime if cordless and whether settings require an app or account. A mirror’s value ultimately comes from even, accurate light—not the number of sensors in its base.
Hair-care claims: how to read them responsibly
- “High speed” can reduce time, but technique and temperature still affect damage.
- “Nourishing” describes delivery of a chosen cosmetic product; the dryer itself does not treat a medical hair or scalp condition.
- Shine and smoothness can vary with humidity, formula, cuticle condition and styling method.
- Safety detection reduces a risk but does not make an automated curling chamber impossible to snag.
Shop carefully for styling essentials
Look for the exact model and authorised seller. A heat-resistant mat and sectioning clips are simple accessories that can make a styling station safer and easier to organise.
Confirm voltage, plug type, returns and seller authorisation before ordering an electrical styling tool.
Which Laifen product should you consider?
Swift 4 makes sense if
- You want a high-speed dryer with granular heat control
- You already use a compatible finishing oil or serum
- You will clean and maintain the special nozzle
- Independent noise and heat tests prove competitive
Wait or compare if
- You prefer a simple dryer with fewer parts
- You have extensions or hair prone to tangling
- You need professional colour-accurate mirror lighting
- Final prices approach established premium rivals
Buying checklist
- Confirm the exact US or regional model, voltage and warranty.
- Read the permitted serum or oil specification before using the Swift 4 pod.
- Compare weight and sound at the settings you will actually use.
- Check AutoCurl barrel size, temperature options and hair-length guidance.
- For Glowy, verify CRI, brightness, magnification and whether it works fully without an account.
- Buy from a seller with a suitable return window in case ergonomics do not suit you.
Final buying advice
Laifen has built a coherent prepare-style-check routine rather than three unrelated gadgets. Swift 4 has the clearest immediate utility, but its serum-delivery feature needs careful compatibility and cleaning guidance. AutoCurl and Glowy could add convenience, yet their value depends heavily on final price and real-world consistency. Treat all three as promising launches, not proven category leaders, until independent testing arrives.
Frequently asked questions
When did Laifen announce Swift 4, AutoCurl and Glowy?
The US announcement was published September 1, 2026. Laifen said Glowy would become available September 4; exact timing for every model and market can differ.
Can I put any oil in the Swift 4 nozzle?
No such assumption is safe. Use only formulas, quantities and cleaning methods explicitly approved in Laifen’s final instructions.
Does Laifen Glowy have a camera?
The announcement highlights a 24GHz radar sensor for presence detection rather than a camera. Confirm the final regional specification and privacy terms before purchase.
Is AutoCurl safe for every hair type?
Laifen describes resistance detection, but suitability depends on length, texture, condition and extensions. Follow the sectioning and compatibility instructions and stop if hair catches.
