I think everyone probably knows about Yves Rocher Hair Vinegar because it's so famous. It's the product that gets rid of the poop smell on the top of your head, which gets worse in the summer. Seriously, the smell really doesn't come out. It works so well that once you start using it, you have to keep using it. I used to only use the green one, but I bought the red one to try, and personally, I think the green one is better haha. I'm going to use this tomorrow morning too.
