I have used this conditioner for years. There are several colors of this conditioner, based on your particular hair color. Mine is the natural brown. I used to believe that using conditioner in my hair made it more unruly and harder to manage, but it turns out that the opposite is true. It doesn't take much conditioner massaged into my hair to get a better style and it helps protect against split ends. This tube of conditioner will last for a long time because so little is used. Because I color my hair, this conditioner seems to protect my color for a longer period of time. Biolage has apparently discontinued this line of conditioner however, when I googled it there are online retailers that still carry it. I am going to miss this wonderful conditionar as I have come to rely on it to help condition my hair and protect it at the same time. Hopefully, they will put out a conditioner that works as well as this one has.
