Fairly low poly object causing lag when parented

Fairly low poly object that don’t cause lag when not parented to the player’s head, cause lag when parented to the head. What do I do?

I would say right now you are reading my reply.

If you talk about lags, always submit the output from profile.

I suspect: Physics, one object is inside another object => Lag, even if one is ‘ghost mode.’ Set the players head to no collision. (Not static ghost, No Collision)
