Shut the water off either below the tap or at the main shut off. If the handle screws around a couple of times, you have a washer in it. Take the handle off, most are held on with a screw in the top of the handle. Under that there may be a trim ring that unscrews or it may just have the nut around the stem. With the trim ring off, unscrew the nut that hold the stem in place and remove it. The stem will now unscrew out of the faucet and the washer is on the end of the stem. It is held on with a small brass bolt. Washer are different sizes, use one that is the same size as the base of the stem.
If your faucet only turns a quarter turn, you have a rubber cup in the base of the faucet that seals the water. The faucet comes apart the same way, unscrew the nut around the stem and with it off, pull straight up on the stem. Make sure you notice which way it came out, it has to go back in the same way or the water will not shut off when you turn the handle. Look in the faucet where the cartridge you pulled out was. There is a black cup slightly larger than a pencil. Take it and the spring under it out and replace it with a new one. It can be a little difficult getting the cup back in, make sure you don't damage the top edge of the cup or the faucet will leak. Reassemble either type and the drip should be fixed.
Buy a new tap.
Try replacing the washer seat.
To fix a leaking washer tap in your kitchen sink, you can start by turning off the water supply to the tap. Next, use a wrench to loosen the nut that holds the tap in place. Once the tap is removed, check the washer for any damage or wear and tear. If the washer is damaged, replace it with a new one. Finally, reassemble the tap and turn the water supply back on to test for leaks.

If it's still dripping after a washer change, most modern mixer taps don't actually use washers — they use ceramic disc cartridges. Replacing the washer on these does nothing, because the seal is in the cartridge, not a washer. Check what your tap actually has before assuming the fix was correct. If it does have a genuine washer and it's still dripping, the usual cause forum discussions point to is limescale on the valve seat — particularly on the hot tap, since mineral deposits concentrate more on the hot side from heating. The new washer can't seal properly against a scaled or pitted seat, so the seat itself needs cleaning or the whole valve replacing, not just the washer. If it's a ceramic cartridge tap, the fix is a new cartridge matched to that exact tap model — generic ones often don't fit properly, which is a common complaint in these threads.

You need either a new O ring in the shower or tap anew washer in the tap, or you should go to the toilet before showering.
Washer worn out, washer seat damaged/corroded The most likely reason is that the sealing washer or seat in the tap/faucet is defective.
Essentially it contains a screw (under the handle) driving a round rubber washer onto the incoming pipe. This blocks the supply, but also slowly destroys the washer after a few years. At this point the washer can be easily replaced.
