Matrix Biolage Smoothing Gel • About this product, don't ask me if it is still in the market or if it has been discontinued, because I don't know. All I know about this product is that I bought it a while ago and after I bought it I put it aside and didn't use it right away. Well, that was a mistake! This product works so good that i now use it daily. I apply it on my hair, dry or wet, and I end up satisfied with the results and to me that's all it counts.
