Review: Good product to use to tame frizzy hair!!!! - Used this product mainly for my very frizzy and highly damaged hair. It is one of the best products I have used that I really see good results. It leaves your hair manageable and soft, but you must follow the instructions. Use it only on dry and shampooed hair. Do not use hair conditioner or rinse only shampoo and let hair air dry. Then apply K18 and style. I am satisfied with this product.
Review: Great buy - Worth the price!
