Hi , I am pretty sure it did not contain Itchyol, that ingredient is only in their shampoos for Psoriazis.
The shampoo that I used in the past is now called Squanorm, but I am not sure if they changed the recipe. http://www.ducray.com/en-gb/node/66917
Now I am using a new one called Kelual DS for Seborrheic Dermatitis which is quite expensive but really effective.
I also started to use the Kelual DS cream (http://www.ducray.com/en-gb/node/66915) for face and ears combined with Biom8.
The combination is really good: Kelual DS cream stops the flaking but sometimes the itchiness comes back, and Biom8 reduces the itchiness and increases the effectiveness of the treatment. I am not cured completely but my skin looks and feels quite normal when I apply this combination.
