It will burn the product of burning Hydrogen if it is dense enough.


Once the Hydrogen fuel has ended, if the Star is dense enough to Burn Helium, it will burn Helium into other heavier elements, if not it will shed its outer layers into Space like the our Sun after 4.6 Billion years or it will end up in a violent Supernova explosion if it is a Star much massive than our Sun.

Usually Stars, the Size of the Sun and heavier are able to burn Helium into other heavier elements.
