In my case, with an oily, sensitive scalp—I have dandruff and my head is constantly itchy—it has helped me a lot. I’ve reached the point where I don’t have any itching at all. You just need to wash your hair fairly often, every two days, for example, to see that it really works. And if you leave it on for a while, that’s good too, because the shampoo can work and leaves your hair slightly soft.

Very nice shampoo, lathers nicely, I have fine to medium dyed hair with oily roots and dry ends and I really like how it leaves my hair after washing.

I used it for several months due to seborrheic dermatitis on the scalp and the need for daily washing (gym, etc.). Even during flare-ups, it helped a lot in soothing the symptoms without using any therapeutic product at the same time, but the long-term use resulted in my hair becoming dehydrated and very thin (even though I applied a mask to the ends). I have now replaced it with another one.

Very good shampoo although it leaves the hair somewhat drier, it removes dry skin and dandruff even at a slower pace than I would prefer

Excellent shampoo, helped me a lot with itching and dandruff, cleans very effectively, compared to other similar shampoos that make the hair oily and do not clean the scalp at all, and provides great relief. Very good gentle scent. Combines perfectly with local cortisone, antibiotic, and antifungal treatments.

I don't want to bash it because from the reviews I see that it helped people...in my case, I will first mention the positives:
it leaves the hair beautiful, gives volume, and has a nice, very soft scent.
On the negatives: it caused me terrible dryness and itching from the first wash. I used it for two weeks hoping that something would change, but I can't continue using it...apparently, some ingredient in it irritates my scalp

It helped with the itchiness I had. My hair doesn't have an oiliness problem but my scalp is relatively sensitive. It has a very gentle scent like discreet powder, which fades after a few hours. A small amount creates satisfactory foam so it won't run out quickly. It's a shame there isn't a corresponding conditioner.

It is the only shampoo, out of all the ones I have tried for daily use, that actually worked and eliminated dry skin.

Perfect shampoo for everyday use without silicone and parabens! I have tried countless products in the last year and this is the best! It spreads easily and creates a super foam with a small amount. We have been buying it for almost 4 months now and we are completely satisfied. At around 9 euros, it is one of the best choices (and it lasts a long time too)! I highly recommend it. (It came to us with a label attached that says it is ideal for children for frequent washing)

I used it on my child. It doesn't have a particularly nice smell (the classic shampoo scent), but my child didn't show any signs of dryness (itchiness, etc.). It leaves the hair soft and easy to comb (very important!).

In my own hair, it didn't work as I expected... it left me with the feeling of a very mild children's shampoo (the packaging says it's suitable for children)...
