SenseIQ technology for a personalized drying experience. The hair dryer’s digital infrared sensor continuously measures the hair temperature for personalized protection. An intelligent microprocessor analyzes sensor data and adjusts the temperature more than 12,000 times during each drying session to prevent overheating. Our detection and adjustment technology protects the hair while drying and retains up to 95% of the hair's natural moisture. The digital infrared sensor constantly monitors the hair's temperature to avoid overheating. While other hair dryers only measure the air temperature, the Philips hair dryer with SenseIQ technology measures the hair temperature. The sensor is extremely precise and detects even the slightest changes, allowing for individualized protection for your hair. An intelligent microprocessor acts as the "brain" of the SenseIQ technology. It analyzes and adjusts the airflow temperature more than 12,000 times during each drying session to achieve optimal performance with exclusive hair care. SenseIQ offers intelligent heat control for a unique way to protect your hair.
