You moved, and within a few weeks your curls stopped behaving the way they used to. The shampoo and the conditioner are the same. It feels like the new city changed your hair, but a move changes many things at once: the water, the humidity, the shower head, your travel and sometimes the stores you buy from.
More than one variable changed
A move can alter water hardness, humidity, temperature, travel routines, shower hardware and the products you can buy. It is tempting to give the water all the credit or blame. A better starting point is to list what changed at the same time and separate facts from impressions.
Use the local utility report to see whether the city publishes total hardness and whether it names more than one supply zone. Keep the report's year and scope. A value for the city is context, not a direct test of your home.

Keep one familiar wash method and style constant for several wash days. If you want to introduce a product intended for mineral deposits, test it once while leaving the rest unchanged. Notice whether the result repeats rather than deciding after one wash.
If your city has a large published range, ask the utility which source usually serves your address. A different apartment building can also have its own treatment. These details are more useful than guessing from the region.
Know when water is the wrong question
Hair colour, heat, illness, medication changes and stress can all affect the experience of hair, and city hardness cannot explain sudden shedding, scalp pain, itching or flaking. Those concerns deserve appropriate clinical support when they persist.
The useful outcome of a move is a clearer routine, not a bigger list of products. Keep the change that is consistently helpful, and leave unproven explanations as possibilities rather than facts.
Sort out what changed
Write down everything that changed in the same month: the water source, the climate, the shower head or filter, your schedule and your products. Separate facts from impressions. You will usually find one or two changes you can actually test.
Choose the change that is easiest to control. Keep your usual method for several wash days, and keep only the change that repeats. Leave unproven explanations as possibilities, not conclusions.
