"Kami tidak punya sampo."

Translation: We do not have shampoo.

[attilagaspar]

shampoo is uncountable so it sounds weird with an indefinite article

[Winmar]

Yeah it should just be shampoo or any shampoo

[Speedy12846]

Why can you not say I do not have a shampoo

[joeldipops]

Because "shampoo" is not a countable noun* in English. I think this is because it is a fluid, and fluids are never really distinct objects. You could say "a bottle of shampoo" however, because bottles ARE distinct objects.

• as I say below, there is a context where "a shampoo" could be used. That's when we are not talking about the physical fluid called "shampoo", but about a specific brand of product labelled as shampoo.

"Do you have a shampoo that will make my hair less oily?"
"Yes, try FreshHead's GreaseAway product"

Should be: We do not have shampoo.

[joeldipops]

My suggested "correct" answer was "We do not have shampoos" which is grammatical, but would refer to a variety of types of shampoo on offer. You're much more likely to hear the "We don't have (any) shampoo" as suggested below.
