"Hypocrisy and irony are words with different meanings, used in different contexts.
Hypocrisy is the state of pretending to have beliefs, opinions, virtues, ideals, thoughts, feelings, qualities, or standards that one does not actually have. Irony refers to if the result of something which is the opposite of what was expected; an ironic event is one at odds with what might have been intended or expected.
I can see how you could think the meanings are similar, but this should help to make the definitions clearer:
So an example of hypocrisy would be a person who claims they hate people who fake tan, but does it his/herself.
An example of irony would be a person who works at a tanning salon, but is as fair and pale as ever."
