I have used this for years and love it
helps detangle my hair
It's the finishing touch my hair needs. I first use it as a conditioner while shampooing, then apply a small amount for styling. Leaves hair light and manageable.

Used as a leave in conditioner, it is the ONLY thing I have ever found to really tame my hair!
I wanted to try it.
The best product of its kind.

light weight hair detangler, have used it for years and can't find anything I like better for not making my hair feel greasy!
Love this conditioner!
Best conditioner I have ever used. Great when rushing and don't feel like rinsing all of it out, it also works as a leave -in without weighing your locks down. I love this stuff! Little bit goes a long way as well.
It leaves hair really soft
Makes my hair feel so smooth and acts as a conditioner as well as for styling!
The best conditioner I have ever found. Tried it at the Raleigh in South Beach...perfectly smooths hair with Zero build up or greasyness and for color treated hair, it brings life to it. Love Love Love it
This stuff is great. You can leave it in. I have long hair which is thinning on top. This grooming aid is awesome. It is like it makes the hair behave exactly as one would want it to. Very light. Not greasy at all!
