ASMR for YOU while I brush my hair topless with my big brush is Free to Download and Watch. If you're not yet experiencing subtle tingles all over your body and if your head. Why do 5 million people watch hair being brushed? Reminds me of that Emilia Clarke interview where she called her butt naked. People rave about ASMR as a self-care tool, and YouTube ASMR channels rack up millions of viewers.
