We guarantee every product we carry in our salon. During our service, we strive to educate you on how much, how often, and how to apply each product. If you find that the product doesn't perform the way you were expecting, feel free to bring it back and swap it out for a different product, or we are happy to show you how to use the product again! We are unable to issue refunds for any products since we will not be able to use them after they've been opened.
