Yess, it comes from warm countries, although the sun these days is too strong, even for the resilient ones, haha.
Oh right, I had forgotten that it works for hair. I also used it before, and they say it can darken hair too. However, you have to strain it before using it on your hair, because otherwise, a lot of residue is left behind even if you wash it well; and it looks like dandruff! Oh no, haha.
