Mine was a shampoo commericial as well.
It was the Infusium 23 commercial, where the woman excitedly exclaims:
"I can actually comb through this hair when it's wet!" That was ALL I needed to hear. {lol} I used it for years, til I tried Synergy's when evaluating their product line.
I was surprised to find that Synergy's hair care stuff is even better, and gave me an even better tangle-free comb out, even when wet. Infact, when I rinse out the Synergy products, ...it's almost like rinsing all the tangles down the drain. corny & cheesy I know, ...but it's true.
