Negative Ion High-Speed Hair Dryer New and unused. Opened for photography, but unused. [Description] Equipped with a 1300W high-speed motor, it achieves an overwhelming air volume with a power of 160,000 rotations per minute. Compared to the conventional 15m/s, the powerful airflow of 36m/s reaches deep into the hair, quickly removing moisture from the roots. Dry completion in just 30 seconds for short hair, about 2 minutes for medium hair, and about 4 minutes even for long hair. Efficiently handles any situation, whether it's the busy morning before going out, caring for wet hair after exercise, or relaxing after a night bath, achieving fresh hair. A reliable quick-drying partner. From 200 million to 500 million, this hair dryer has made a qualitative leap in negative ion content, and the emission amount has reached 2.5 times that of the conventional model. High-density negative ions envelop each strand of hair, neutralizing static electricity on the surface and quickly suppressing frizz. In addition, by firmly closing the cuticles, it prevents moisture evaporation and keeps the hair moisturized. Through the dual effects of neutralizing static electricity and sealing the cuticles, friction between the hairs is reduced, resulting in a smoother finish after drying, making it less prone to tangling even when brushing. The large air volume is equipped with a built-in NTC smart temperature control system that accurately monitors the temperature of the air outlet 100 times per second, firmly fixing the air temperature to the 57°C gold hair care temperature range (temperature fluctuation is kept within ±2°C). Not only does it prevent heat damage to the scalp caused by high temperatures, but it also suppresses cuticle damage. Meanwhile, the Z-shaped long-path air duct structure assists in heat dissipation and evenly diffuses the airflow. By avoiding localized high-temperature concentration, the load on the NTC temperature control is also reduced.
