A noun phrase typically consists of various constituents; the head noun is obligatory but other slots may be optional. These are determiner, adjective(s), noun modifier(s), the obligatory head noun, prepositional phrase adjectivals and dependent relative clauses.
If the head is a pronoun, there cannot be a determiner.
