The only way for a star to fuse (most) of its hydrogen, without being stripped by, or colliding with, another object, is to have a fully convective hydrogen burning stage. Unless there is some exotic stellar composition and dynamics I am unaware of, the only stars which are fully convective during their hydrogen burning phase are red dwarfs (under half a solar mass or thereabouts). All higher mass stars have a mix of radiative and convective zones.
In the higher mass stars, by continuity of the pressure and temperature gradients there will always be a region of the star where hydrogen burning is possible. Once you establish a meaningful "helium core", the star not being fully convective, combined with this region, means there will necessarily be a shell of hydrogen burning going on around it, both before and after helium fusion initiates.
Red dwarfs, however, while fully convective, will never be capable of helium fusion. They simply can't reach the necessary temperatures and pressures. Given a prodigious amount of time (trillions of years), they will fuse a vast proportion of their hydrogen into helium and then essentially just shut down all fusion.
Maybe a collision and merger of two thusly exhausted red dwarfs could produce helium burning with no significant hydrogen burning shell. I'm not sure if that's been modeled (not nearly enough time has passed for such objects to exist within our universe), and am not sure it would not result in a supernova of some form.
