I've been using this product for a few years. I use it every time I wash my hair as a lightweight leave in conditioner (though the bottle states that you can rinse it out, if you like). Because I have fine straight color treated hair it took me a long time to find a leave-in conditioner that moisturized my hair without weighing it down or making it look 'greasy'. I like this product so much that I always keep a back-up bottle to use when traveling. I highly recommend this product!
