This commercial is noteworthy for several reasons. There’s the inanely catchy “Defrizz the Frizzies with Tame” jingle. And there’s the before and after demo which barely shows any reduction in frizz at all. Then there are the deliriously happy models who, despite their frizzy hair, seem more than content to pet puppies and toss their hats in the hair.
The beauty science bit is that, even back in ’70s, Tame used “cationic conditioners” to defrizz hair. Cationics are positively charged so they stick to the damaged spots of hair which have a negative charge. Along with silicones, these are some of the most powerful conditioning agents are are still in use today.
