Behold my super fancy hair-washing station…on my kitchen floor. I don’t have hot water in my house, and in the winter it feels like the liquid coming out of the taps has been piped directly from the Arctic Circle. I boil some water overnight, let it cool, and then boil some more in the morning and mix the two. The water here is hard and has a ton of minerals and silt in it, so boiling the water slightly reduces the amount of gunk that ends up in your hair.
This is the kind of insider information you aren’t going to get anywhere else, people.
