How do I use a promotional code?
If you have a Kérastase promotional code, you can let us know before confirming your order by inputting it into the field, "Promotional Code".Once the code is entered, the offer will be directly applied to the amount that your shopping bag totals.
You will see the title/value of your code above the subtotal amount. You have the option to cancel the code you entered and enter a different one.
