Hi I am from Europe (Germany). I would check if there is a "DM" market anywhere. It is kinda like a Walgreens.

I recommend:

ALVERDE Birke-Salbei Conditioner as co-wash
BALEA Aprikose Conditioner als Conditioner or leave in.

Have fun in Europe!

Oh and basically in Europe, the cheap stuff is without cones, the more expensive, the worse the ingredients...
