You know, almost all the recent shampoo commercials I can think of off the top of my head don`t feature blondes. In fact, I can`t think of a single commercial with a blonde. Even the most "European Image" Mod`s Hair uses a brunette.....
All the others used older women (Showing them having fuller hair) or mothers (washing their hair with their kids).

Tsubaki is just the very latest of the "Japanese image" shampoos. Before it there was that one that used breast milk essence, and then that Asience one...
