"The first way to fix a slice is by adjusting your grip. A weak grip (where the hands are rotated too far to the left) can cause the clubface to open at impact, resulting in a slice. By adjusting your grip to a more neutral position, you can square the clubface at impact and hit straighter shots"

"The second way to fix a hook is by adjusting your swing path. A swing path that is too much from the outside (where the clubhead approaches the ball from the outside of the target line) can cause the clubface to close at impact, resulting in a hook. By adjusting your swing path to a more neutral position, you can square the clubface at impact and hit straighter shots."
