Your key to a mermaid mane could be a shower filter. One Redditor called Rivkariver wrote about how they experienced an amazing transformation after swimming in lake water. The next morning, Rivkariver expected to wake up to a "rat's nest," but instead found "astonishingly soft, tangle-free, smooth, and non-frizzy hair. It brushed through so easily." This led the Redditor to buying a shower filter "to take out chlorine and heavy metals" from their water supply.
But according to another user who goes by the username HollaDude, "Keep in mind that if you're in an area that uses chloramide instead of chlorine, than the water filter won't be able to remove that." Not sure? Check with your town or county's office to learn more about your water supply.
