Every star is different in this regard. Our Sun started out mostly hydrogen, but with traces of heavy elements; this is how we know that our solar system came from the remnant of several supernova explosions.
Today, after about 5 billion years, the Sun is now about 70% hydrogen and 28% helium, and 2% other heavier elements.
