It works only for the first load

Hi, this is working well for the first load. I start in the home page and the custom css is loaded, then when I go to another page/list the custom css is removed, then I get back to the home page, the custom css is removed as well. But if I hit F5 then the custom css is loaded again. So, do you know if we have to use the Render method in an extension component? Or I am doing something wrong?
Thanks,

I did another test in a Team Site and so far, it is working, but my first test was in a Communication Site and the css script does not load in all pages after the first time the page was uploaded.
