I purchased this new online and used it for about 3 months. I am selling it because I bought a new hair dryer. There is a small dent on the right edge of the box (see image 4), but the main unit is in beautiful condition. Everything in the photos is included. The air intake has been boldly hollowed out, achieving high airflow and ultra-lightweight design. ● Equipped with Cure Crystal Diffuser ZERO Various natural minerals and mineral powders that emit terahertz waves, a type of far-infrared radiation, are micro-powdered and uniquely blended. This is processed into the dryer's air vents, nozzle, and the inside of the main unit. Depending on the temperature setting, terahertz waves with different effects are generated, such as quick-drying, moisturizing, and cuticle repair. By using the temperature and airflow according to your purpose, you can achieve hair quality and damage care beyond the functions of conventional hair dryers, as well as create the base for styling. ● Terahertz Technology By combining various wavelengths of terahertz waves, also known as "growth rays," within far-infrared radiation, it increases hair moisture, cares for the scalp, repairs cuticles, and also provides quick drying, volume up/down, style retention, and anti-static effects. ● BLDC motor adopted Compared to the motors used in general hair dryers, it is equipped with a small brushless DC motor with a high motor rotation speed. It is highly durable, and because there is no friction from carbon brushes, it emits a clean, even airflow with high power. Enables speed drying. ● 5-step temperature variable function / cold air switch You can adjust the temperature in 5 steps: 40℃, 60℃, 80℃, 100℃, and 120℃, according to individual hair types and damage levels. With a single switch, you can quickly switch from hot air to cold air. By applying cold air for finishing, the shine and texture of the hair are further enhanced. ● The air intake has been boldly hollowed out, achieving a lightweight design of only 350g. Furthermore, it is equipped with a clean mode for easy maintenance. In addition to the BLDC motor, the air intake is hollowed out, and the number of parts is minimized. Achieves a compact body that is the lightest in the industry at 【350g】, making it less tiring even with long-term use. *Compared to 1400W professional hair dryers. *Press and hold the cool button for 5 seconds to switch to cleaning mode.
