|a Hair is a potential transmission barrier for diagnostic and therapeutic ultrasound. We tested hair phantoms for insertion losses and field effects at 0.27-2.8 MHz. The negligible losses observed below 0.5 MHz suggest that, at such frequencies, hair removal is unnecessary for low-power imaging or therapeutic applications
