The most common cause of this is when the tap's O-ring becomes worn over time. This makes the tap harder to turn due to extra friction and for those without strong hands, a stiff tap can become impossible to use.
Because your faucets are more prone to mineral buildup, it's not all that uncommon for that buildup to cause a little friction inside the handle. Fortunately, this isn't usually cause for alarm and can be fixed with a little cleaning and a little wiggling.
Stiff taps can often be resolved by lubricating the spindle or cartridge. Disassemble the tap, apply a suitable lubricant, and reassemble.
Spray WD-40
If your notorious tap is still not working well, you will need to show the magic of WD-40. Take your can of WD-40 Multi Use Product, shake it well, and spray it on and within and crevices of your tap.

Clean or Replace the Faucet
Clean out the inside of the faucet valve with vinegar, and repeat the cleaning on the cartridge. Inspect for metal shavings, worn parts, grit, or mineral buildup. A scrub brush can help loosen deposits. Use the plumber's grease to lubricate any threads you can see.

You can try some WD40 or some hot water over the valve to try and loosen it. When you have undone the cartridge you will get a small amount of water seep out, have a cloth handy to mop up this water. Your cartridge may come out with an adaptor bush /conversion ring attached.
If the handle is stiff to rotate without the cartridge, then it is possible there may be some build-up within the handle preventing it from rotating smoothly. Try soaking your handle in a 50/50 solution of white vinegar and water for 30-60 minutes to see if this helps clear the build-up.

In some cases, a faucet that won't turn off may be caused by a malfunctioning cartridge or handle mechanism.
You may find that the handle on the stopcock has seized up over time, especially if it hasn't been used in a while. If that's the case, you can spray it with some of the penetrating oil to help loosen it up. Once you've got it moving, turn the handle clockwise until it's fully closed to turn off the water supply.
If it is difficult to turn, we suggest applying some WD-40 Specialist Fast Release Penetrant on the threading, which quickly penetrates and loosens the tap for easy removal. The formula is also water-resistant so it will work even if there is residual water.
Give it a good spray of WD40, then (although it sounds strange) tighten it slightly, then loosen. Repeat the tightening and loosening process until it works its way free. Also, I would put a wet cloth under your grips to give yourself a bit more purchase on it.

Water-miscible cooling lubricants for taps
Because water conducts heat well, these lubricants are especially effective in dissipating heat generated during the machining process. Water-miscible coolants contain additives like emulsifiers, antioxidants, and corrosion inhibitors.
To clean these areas, fill a small sandwich bag with distilled white vinegar. Secure the bag to the mouth of the faucet using a rubber band. Make sure the mouth of the faucet is fully submerged in the vinegar. Leave the bag in place for at least one hour.
Use your hair dryer to heat up the valve body to melt any gunk and grime that's built up and solidified into an adhesive. Once you can feel the valve turning, wiggle it back and forth to let the gunk and grime wash away. Use your wrench to loosen the bonnet or packing nut.
