Yeah, I deal with hooked nails, and it's a problem, especially for the middle finger, which swings through the biggest arc. You might find something

Some people heat and reshape the nail, though I haven't had much luck
doing that, and instead make the nail pretty straight from the contact
point to the release point (assuming first contact at the thumb side),
which in my experience lessens the effect of the hook. Charles Duncan's
book 'Art of Classical Guitar Playing' covers this as well as any I've seen
so far. Might be a place to start... first causes could be looked at, too.
