"SonoRepro" is the world’s first handheld haircare device that applies vibration pressure from ultrasound waves to stimulate the scalp. Making this possible is our proprietary “non-contact vibrotactile stimulation” technology. It’s designed to concentrate ultrasound waves in the air onto a single point on the scalp at a time, providing stimulation without making any direct contact with the user’s head. We envision further applications of this technology for haircare.
