Cold air VS hot air: Which is better to dry my hair?
So, which of the two is the air-drying method to go for if you want to dry your hair – cold air or hot air? Well, it all boils down to your personal preference.

The hot air works wonders if you want your hair dried up fast and shaped well, particularly if you have coarse or thick hair. However, it could be very harsh on your hair if overused.
The cold air, although slower, is gentler.
It makes your scalp feel soothed and your hair, which could be damaged, look fabulous.
| Cold air drying | Hot air drying | |
| Drying time | Takes a bit longer | Dries your hair super fast |
| Hair health | Gentle on your hair, seals cuticles | Can be harsh, might cause damage if overused |
| Frizz & flyaways control | Decreases frizz, adds a nice shine | Can make frizz worse if used too much |
| Styling | Setting styles and adding volume | Shaping and quick drying |
| Heat sensitivity | Fine, fragile, or damaged hair | Thick, coarse, or resistant hair |
| Moisture retention | Keeps your hair’s natural moisture | Can dry out your hair if overused |
| Comfort | Keeps your hair’s natural moisture | Can be too hot and uncomfortable |
How to protect your hair from heat damage and frizz by?
Hair styling can sometimes be difficult when using heat styling tools; however, the Laifen Swift dryer makes it that much more simple for you. Learn some tips on how you can avoid having frizzy hair.
Step 1. Choose the right temperature

The Laifen Swift’s 4-color LED ring isn’t just for show. Use the yellow setting (warm air) for most of your drying to be slight on your hair.
My own friend who has great hair always uses this technique, and she claims that it helped keep her hair soft and shiny, without the typical split ends.
Step 2. Smart usage of the circulating mode
The thing I like about the circulator is its ability to change from hot to cold air automatically when you press the temperature button for two seconds.
Step 3. No need to forget heat protector

While the Laifen Swift hair dryer is specifically created to help minimize damage, using heat protectant is always recommended.
In my experience, I can see that using heat protectant, together with careful settings on the Laifen Swift, makes my hair less brittle.
Step 4. Section-dry your hair for optimal effect
Rather than applying high heat to your entire head at once, spend a bit more time section-drying your hair.
Not only will this ensure uniform drying, but this way your hair won’t be exposed to excess heat anywhere.
Step 5. Close the hair cuticles by cooling
When your hair is almost dry, move the dial to the blue (cool air) setting. This cold air is useful to close the hair cuticles and lock moisture inside the hair.
Finally
Laifen hair dryer rings and lights may grab your attention with their stylish and futuristic look, but there is something far more practical about them than just looks.
These LEDs show the temperature and provide a great way to regulate the temperature to keep your hair safe. The design approach used by Laifen makes it stand out from the crowd.
