Adjusting faucet handles becomes necessary when the internal rubber sealing washers wear from use. The washers are compressed by the turning of the faucet handle, which in time causes the handle to be rotated further to fully shut the flow of water off. The forming of the washer under compression is normal, but when the handles lose symmetry in their appearance as a result, each one can be adjusted to their original position. You can adjust the faucet handles with a screwdriver and basic hand tool experience.
Ensure that the faucet is turned off and that no dripping is present.

Lift the handle up and off from the faucet stem.
Reset the handle in the desired position.
