A suitably trivial topic for Chat, but I was in the shower and noticed on a tube of shampoo a caption saying
"No buildup formula (so you never have to switch)".
Maybe I was off sick the day at adult school that they taught the topic of shampooing (never really understood what conditioner does), but what on earth does the above mean?
"You never have to switch" - do they mean you never have to switch to another shampoo? What is "buildup formula" and why does its absence mean you never have to switch?
