Fast delivery without any problem. I have experienced this in my hairdresser who does unfortunately. I have normal hair and I wash 2 times a week. This shampoo makes hair soft and shiny and is very pleasant to use (odor-structure). With the amount, I advance it's perfect. A small flat, the closure system, I had hoped that the cap fits that of the small vial with the plunger but not so damage. I am left to keep my piston and pour bottle as soon as it is empty. Quantity / price very well.
