Shampoo fine for colored hair, too pricey

On the advice of my hairdresser, I have been using this shampoo for my colored hair for a year now. It is a fine shampoo that gently cleanses the hair with a wonderful scent. The shampoo is also paraben-free. I have the 250 ml package and therefore find the shampoo too pricey (about €22), you will take it for a long time. The shampoo does not foam very much and for my sometimes greasy hair type it cleanses too gently. I also don't experience that my dry hair is very cared for by this shampoo, it does retain the color in my hair nicely. All in all, a nice shampoo but too pricey for what it is.
