Header Woocommerce shop and product pages

I want to add a header to the default Woocommerce shop and product pages. But when I add anything, the page gets messed up. When I only change the header setting to transparent, nothing happens. (Links in private content).

I managed to ‘build’ a custom page, using the product grid in the Avia layout builder and adding the widget area in a column. This results in what I exactly need (link in private content again). But when I click to a category, product selection, product search, single product page, or whatever, I get the default shop page again, without the right header settings.

Is it possible to create a page and ‘point’ an area where to put the complete assortment, an active selection, single product or whatever?

Thanks,

Sytse
