I bought it as my last hope against my daughter's excessive scalp oiliness, who has long and thick hair. It is the only shampoo out of all the ones she has tried that keeps her hair non-greasy for two days without making the roots shiny!!! Of course, a hair mask is needed, definitely, because it dries out the ends!!! The downside is, of course, its price, although with a small amount, it lathers well!! However, it does what it promises!!!!!!

Very nice shampoo, makes the hair very light, resulting in a richer appearance. It significantly reduces oiliness, allowing the hair to stay unwashed for an extra day. I wish it had a conditioner!

I have been using it for a month now. In the first few days, I noticed a slight difference, but ultimately my hair still needs to be washed every day. Not effective at all

I have been using it for about 2 months, every other day. It had some effect in reducing oiliness, but to a small extent (my hair would get oily within 24 hours after washing, and with this product, it would last about half a day longer, not that significant though, but there was some difference). The downside is that it caused dryness, red marks, and itching, so I stopped using it. I had to switch to a shampoo for dry skin.

It did not help at all with oiliness. The only thing it actually did was dehydrate the hair and make it look damaged. No removal of impurities and no lightweight feeling. Do not prefer it.

Many promising according to the advertisement but not as effective. The previous Dercos shampoo for oily hair, the sebo-correcteur, was exceptional and much better, it gave more volume and shine to the hair. I wonder why they changed it.

Although the advertisement seems promising, unfortunately, this specific product did nothing for me. After washing, a conditioner must be used because the hair does not untangle. Also, the hair remains fresh and lightweight for only a few hours after washing. It has a nice, subtle scent, but it does not deliver on its promises.
