I have used this product
I have used this product for over 2 years. It has been the only thing that has helped my dry, bleached curly hair. I originally got the smaller bottles but the refill turned out to be the most cost efficient. Typically a normal bottle will last me 2 months, so I can imagine how far the refill will last. Whenever the refill finishes I will purchase another. Not only is it light weight but super moisturizing. My hair stays styled for a week. And I only need to use one product. It did take a while to come in but not terrible.
