What I mean by that is... If you wash your hair with cold water, have you a better chance of rinsing your hair with less limescale than if you used hot water?

Hot water tends to contain more impurities. It is more likely to dissolve metals and minerals and carry them through the piping.

Does cold water has more pressure than hot water?
It depends on how you define "pressure." In general, pressure is the amount of force applied to a particular area. If you are talking about the pressure the water (or any liquid) applies to its container, hot water is indeed "stronger." This is because the molecules of hotter substances move more rapidly, and in all directions - including "outside." (In fact, this rapid movement of molecules is precisely what temperature is.)On the other hand, if "inner" pressure is what concerns you, cold water (orcold anything) is stronger, for the converse reason - the molecules are moving more slowly and staying more "together." Hence, cold weather is of a higher pressure than hot.This phenomenon is naturally related to the two other phases of water - if the water becomes cold enough, its molecules more or less stop moving altogether and it freezes into ice (and no situation is of greater pressure than getting frozen!) whereas if it moves rapidly enough, the molecules' bonds will break apart more or less altogether, and it will evaporate into steam (which has enough pressure to power a locomotive piston!).
What differences are there when you use hot or cold water in a lava lamp?
hot water contains more energy than cold water. cold water causes the water molegules to vibrate more.
Are molecules in hot water different then molecules in cold water?
If you have the same volume of both then there are in cold water more molecules.
Why do you feel more cold after taking a bath with hot water as compared to cold water?
because when you get out of the baths of hot water its a bigger change in temp rather than after you get out of one with a cold water than the temp in te house will be warmer than ur bath
Is hot water less dense than cold water?
Yes, because the higher the temperature, the faster and more spread out the molecules, therefore making hot water less dense than cold water.
Why is hot water pressure low but cold water pressure is good?
More than likely it is restiction in your water heater.
How much air is in hot water Is there more air in cold water under the same pressure of course?
Colder water can hold more oxygen than warmer water.
Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
Can warm air pressure weigh more than cold air pressure?
yes
What is more dense cold water or warm?
cold ocean water is more dense than warm water
Is warm salt water more dense than cold salt water?
Cold water is more dense.
Cold air exerts more blank than warm air?
air molecules in cold air exert more pressure because they are closer together and collide more often

Does mercury exert more pressure than water?
mercury exerts more pressure than water bcause mercury is a metal and water is a non metal obviously mercury weighs more than water
Why does water exert more pressure than air?
Water is more dense than air is.
Why the cold water pressure less than hot water pressure?
Depends where you are testing it. Possibly just a plugged aerator, or a broken seal.
What does it mean if your hot water pressure is less than the cold water pressure?
My guess is that the hot water heater is installed downstream from a pressure reducer to limit the maximum water pressure that the water heater is exposed to.
