<?php if ( apply_filters( 'woocommerce_show_page_title', true ) ) : ?>
<?php if(!is_shop()) { ?>
<h1 class="page-title"><?php woocommerce_page_title(); ?></h1>
<?php } ?>
<?php endif; ?>
For reference conditional tag of woocommerce
OR
<?php if ( apply_filters( 'woocommerce_show_page_title', true ) ) : ?>
<?php if(is_product_category()) { ?>
<h1 class="page-title"><?php woocommerce_page_title(); ?></h1>
<?php } ?>
<?php endif; ?>
