Been using the Vichy Decros Oil Control Shampoo for 5–7 years, and I honestly wouldn't switch to anything else. It's hands down the best shampoo I've used for oily hair. It keeps my scalp feeling clean, balanced, and fresh throughout the day without drying it out. If you're looking for an effective shampoo to help control excess oil, I highly recommend giving this one a try!

There is no information about how many times or the frequency of using it . Also one site says leave on for 1 minute and another 2 ... ?

Great for oil control and also hair loss, 2 pumps for each hair wash is already enough

Très bon pour les cheveux à tendance grasse, ma fille l'utilise régulièrement

It is the only shampoo I use, makes my hair look and feel clean. Love the smell!

Perfect shampoo for my oily scalp. With this I can skip a day without shampooing.

I did not find this shampoo was any different than any other much less expensive shampoo I've used. My hair still felt like it needed to be washed again after 24 hours. Not only would it feel oily, but my scalp also felt itchy. So in short, this shampoo is not worth the cost.

Vmt bien après une utilisation fini les démangeaisons et les cheveux viennent beaux

Works well, keep my scalp clean and less oily and almost never doing pimples anymore

Since I started using this shampoo, my scalp has never been better!! It gives volume without over drying. It soothed my itchy scalp and my hair loss has considerably decreased.
