>>19872299Head Smash prevents recoil damage from moves (except Struggle), but not from use of a Life Orb, Jaboca Berry, or Rowap Berry. Crash damage is still received if Jump Kick or High Jump Kick misses.
If Head Smash is lost in a turn due to using a recoil-inducing contact move on a Pokémon with Mummy, the HP loss from recoil will occur that turn.
