It's really a water quality problem. Tap water in Europe can be drunk directly, but the water quality is "hard". The so-called "hard" is because tap water in Europe generally contains high calcium content, especially the higher the calcium content, let alone drinking it, even if you wash your hair, it will have an impact on your hair quality.

But Europeans are not particularly concerned about the problem of hair loss caused by this "hard" water. I remember when I first arrived in France three years ago, I was very eager to find a place to sell or receive water in the teaching building, so I found a professor (it turned out to be our dean. . . ), he calmly said: the toilet faucet is unscrewed and directly drunk. . . I have really seen French students go to the toilet to drink tap water countless times, and the school cafeteria can drink water by itself, which is actually tap water. . .

And there are many products for treating alopecia in Europe. Every time I go back to China, I will bring my father the famous French Flo Deya. I myself, including all China students I know, use anti-hair loss shampoo when washing my hair in France. It is because the water quality in Europe is easy to cause hair loss, so there are really many anti-hair loss products in Europe.
