The context may be seen with the following conversation between two men in a British Tv series.
-I had a casting. I'm an actor. This is what I do when I'm not working.
- What was the casting for?
- Head and shoulders.The shampoo giant?
I guess it's a kind of a giant bottle of shampoo,but I'm not sure about it.Any help will be much appreciated.
