Generally, every time my shampoo runs out, I change it with a different one in the hope of finding what I am looking for: not having to wash my hair every day due to excessive oiliness. So far, I haven't found it and this shampoo is no exception. I can say that it keeps my hair less clean than other shampoos I have tried. A big drawback for me is that it produces a lot of foam even on the first wash with very oily hair, a behavior that I have only encountered in supermarket shampoos.

Now that I have been using it for some time, I can confidently say that it is by far the worst shampoo I have tried. It does the same job as the well-known supermarket shampoos.

Indeed, this shampoo is worth it. I used to wash my hair every other day. With this shampoo that I purchased from a salon, my dandruff has indeed disappeared and my hair smells great and I don't wash it as much as before

Compared to any shampoo I have used for oily hair so far, this one keeps my hair oil-free for two days. It has a nice scent and I only need to use a small amount, so logically it will last me a long time.

From the first time I used it, my hair didn't get oily earlier than the day I had to wash it. I have oily hair and I wash it three times a week. So far, I haven't been using it for a long time, so I will give it some more time before writing a more comprehensive review.
**After using one package (almost 5 months), I can say that it does a good job with oiliness, but lately it has caused me a little dryness.
