If you are hooking the ball or slicing you need to adjust the height of the tee. If you are slicing the ball that means you are swinging down too steeply thus creating too much backspin and side spin. Usually when a golfer sees this happening he adjusts the tee lower. These just makes you swing steeper at the ball.

To fix a slice you need to hit up at the ball not down, therefore you should tee the ball higher. At address half the ball should be above the top of the club head.

Hookers tend to swing too far from the inside and get the club trapped behind them, and from there they have to use their hands to release the club, which produces the hook. Hookers should tee the ball lower so that the club will be in front of your body on the downswing. In short slicers should tee up higher and hookers should tee lower.

As in the slice, the hook is often a product of an improper grip. Start by looking at your current grip. Remembering the basics of the golf grip, you should only see 2 knuckles of your left hand. If you see 3 knuckles, then you have a “strong grip” and this maybe the cause of your golf hook.

You can fix your hook by trying to change your grip to a “weak grip”. Turn your hands slightly counter-clockwise on your grip, (opposite for lefties), thus weakening the grip. Grip pressure is also a key element in the release process. If the pressure is too loose at impact then the tendency will for the club to release too early causing the ball to hook.

Remember the basics and only hold the club tight enough to keep control. You should not have any tension on your wrist and forearms. Practice the grip and check your results. Changing your grip should be slight, over compensating can cause other problems with your swing or begin to cause you to slice.
Most golf hooks are from a “strong grip”, but in order for you to correct your hook properly; you must have the know-how and learn the basics of the golf swin
