Explanation:

Locard's Exchange Principle states that when two objects come into contact, there is an exchange of materials. Hair adhering to surfaces and being transferred fits this principle. Secondary transfer refers to transfer from one object to another (e.g., hair on a carpet then to a person's clothing). Direct contact is just the initial contact. Volume transfer is not a standard term in this context.
