Davines Alchemic Shampoo Silver - 250ml

I have been using this silver shampoo for nearly one week now and I think that it really works on my hair, leaving it a little bit "powder white" which is one of the popular looks at the catwalk right now, I must say, though, that it is quite expensive on the long run compared to other shampoos, as I have to wash my hair twice before it really feels clean. First time I wash it, it is impossible to lather up and work with the shampoo; it is first possible to work the shampoo into my hair the second time I wash it.
