Add header to Product Page - Hyde template 7.0

Site URL: https://www.browsbydee.com.au/shop/tint-and-tweeze-kit

Hi guys,

I'm using the Hyde template in 7.0 for a client and currently have a transparent header set up site-wide with white nav font and logo, although I can't find anywhere to add a header to the product page? I figured it would just replicate the /shop page header but it doesn't unfortunately so it's white on a white background.

I managed to find some css code for the Shopping Cart page and have made it black but can't for the life of me work out what the code would be for each product page.

Any help would be greatly appreciated!
