Hello,
You can do this using custom CSS. Go to Theme Options > Header > Fixed Header > enable fixed header.
Then go to Custom CSS area and add the following code
.woocommerce:not(.home) .fixed-header.fixed-enabled, .page:not(.home) .fixed-header.fixed-enabled, .blog:not(.home) .fixed-header.fixed-enabled, .single-post:not(.home) .fixed-header.fixed-enabled {
display: none;
}
Regards
