This doesn't look like a lot of product but it gets the job done!! I have extremely dry, bleached, damaged hair. It took me about 3 tubes to see a noticeable difference over the course of a week and a half, so like any product, it needs time. It does claim that one tube is a week of treatment, and for my friends whose hair is not as damaged and dry as mine it is, but for me i need to use one every time I wash my hair to keep the effects of the product (so 2 a week). This does make my hair look less damaged and feel softer (and less dry). It also reduces the number of split ends I get. This is not meant to be a substitute for conditioner, it is used after shampoo, then you decide if you want conditioner first or after but you still have to use it! I tried to sub this in for my conditioner and saw very minimal results, for the product to work optimally you need to add it to your routine as an extra step not a sub for another step. This product is great and I would recommend it to anyone who wants their hair to be a little healthier.
