The text strings ‘You may also like’ and ‘You may be interested in’ in WooCommerce can be changed with the gettext filter…

 

add_filter( 'gettext', 'bt_translate_like' );
add_filter( 'gettext', 'bt_translate_like_cart' );

function bt_translate_like( $translated ) {
	$translated = str_ireplace('You may also like…', 'Complete the look ', $translated);
	return $translated;
}
 
function bt_translate_like_cart( $translated ) {
	$translated = str_ireplace('You may be interested in…', 'Complete the look… ', $translated);
	return $translated;
}


Change to your desired text by changing the text in the second part of the single quoted string – in the above it is ‘Complete the look…’
