It actually does nothing. I'm not sure what I expected. I checked repeatedly to see if the batteries were inserted correctly. The massage feature functioned so I'm assuming it worked...just not as advertised. It made zero difference in my hair. It did not decrease the static. It did not lessen the amount of frizz. My hair is a little frizzy and a little wavy. I wouldn't recommend this product.
