CHI recently released a new hair dryer that requires no buttons to function. Instead, it has a touch screen that allows you to regulate the power, heat, and ions based on your hair type. Is it too good to be true? We put the CHI to the test against a dryer of similar strength to see if it delivers better results — and if it's truly worth the beauty investment. Disclosure: a sample of the CHI Touch Screen Dryer was provided by Pierce Mattie Public Relations.
