Polylang front page style

I'm using polylang plugin and made a different template that call a specific css file for my other language - > its work great at all pages except the front page. probably the hierarchy.. what can i do to force the front page in my other languages to apply the different style as well, like the other pages. I saw that polylang have in there documentation some options to work with the languages names /id's and other stuff. my q is what and where i should place the "if statement" to switch the front/home page style or the unique template for other languages ?

Thanks in advance.
