"I need to buy some shampoo." I know that this sentence is really easy to get, but sometimes these kinds of simply sentences drive me crazy. So my question is about usage of "some". In this sentence, do native English speakers feel that "some shampoo" means "more than one shampoo" or "uncertain shampoo" or either way can be possible, depending contexts? What do you think? and I really appreciate your help. Thank you again.

'Shampoo' is an uncountable liquid, so 'I need to buy some shampoo' means that I am running out and I need to buy a new bottle of it.
