K18 is a science-backed hair care brand known for repairing damaged hair from the inside out. We like shopping at their online store because they often share coupons that we can redeem for free shampoos or conditioners. This gives even more value to each purchase we make of their products. Another selling point for us is their patented peptide technology. It works in just four minutes to help reverse damage from bleach, color, and heat.

Don't worry, it's similar to how you would use them for other online retailers. Here's how we do it:
Add any products to your bag.
Click the shopping bag icon in the top right.
Click the "Checkout" button. Don't use the "Express Checkout" buttons like ShopPay or PayPal yet, as they sometimes skip the page where you enter the code.
On the right-hand side, you will see a box that says "Discount code or gift card."
Type your discount code and click "Apply." The savings should be indicated on your order total now.
You can write a review for your approved transactions.
