To hide the price on the Hair Routine Builder product page without using any code, go to your Shopify admin and navigate to Online Store > Themes, then click Customize on your active theme. Once in the theme editor, open the specific product page for the Hair Routine Builder. On the left-hand panel, locate the section that displays product information — this usually includes the product title, price, and description. Click on the price block, and if available, use the toggle to hide it or select “Remove block” to delete it entirely from this template. If your theme doesn’t allow hiding the price for just one product, you can duplicate the product template, assign it only to this product, and then remove the price block from that template version. This way, the price will remain visible on other product pages but hidden only on the Hair Routine Builder page.
